- In this video Fish Veterinarian Dr Loh investigates a Lake Malawi cichlid tank to find out what is causing newly introduced fish to die within 12 hours of introduction.
It's important to realise that just because your resident fish are doing OK, if you do not monitor your water conditions closely, it could over time shift to a point outside of the normal comfort zone for most fish, and beyond the normal tolerance levels of what newly introduced fish can handle. So it's critical that before adding new fish, you careful check all water parameters including the temperature to ensure your newly introduced fish are entering a hospitable environment.
Dr Loh also shares with you a simple way on how to check if your thermometer is working accurately.

Always great to see you! This poor owner was doing all the right things but technology failed him and those poor fish. I hope all will be well now . Great detective work!
Hi Dr. Could you please make a video giving tips to quarantine fish before putting them in the main aquarium? There is no good information about a procedure done by a vet.
Salamander Fangskin i am today u can watch
There's plenty of info all over the internet. You do not need a vet to show you. SMH
@@mikedavis8026 Pure ambiguous information from people without knowledge or license. Dr Loh is an authority on the subject of fish diseases and how to treat them.
Salamander Fangskin I agree.😀🐠
@@SalamanderFangskin true. Really want to hear professional opinion on thi matter.
Love your videos, I'm a Brazilian clínical pathologist veterinarian who loves fish medicine and unfortunately the sources about fish medicine is so hard to find here, you share great informations and tips, looking forward to seeing new videos showing stuff under the microscope hehe
0:56 that dog is giving Dr Loh the stare down of the century
Good one Doc! Hey I've always been curious. What kinds of fish are you keeping, Doc?
I like the technique you use to measure accuracy of thermometer probes.
An expensive house call for a broken thermometer lol.
Some people lol
Thank you for another very informative video.
As soon as I saw the thermometer in the video.. Yep. I had the same one. It broke after only about a month. It slowly over time kept reading lower and lower. Luckily, my Fluval heater has it's own temp display so I knew one was off.
Geez...even when I had a 25gal tank I always kept two temp sensors in the tank (one passive, one active) just to make sure if one was reading off I'd know right away. Not doing that for a tank this size is like buying a Ferrari but skipping the insurance.
Who would've thought, right? Makes me want to purchase another heater for my tank!
Elisa Milan I was told by some knowledgeable fish keepers on RUclips to keep an extra heater in case one malfunctions you won’t panic because you will have been prepared.🐠😀
God to see you back Doctor. Stay safe and stay strong 💪
Goldfish Corner I found this video helpful.
Great vids mr. Dr. Loh
Eheim heaters are also not reliable at the set temperature. Even after much calibration, it wouldn't run at the set temperature. For my 680L tank, I set the heater at 28c but the actual temperature ( measured with two separate thermometers) was at 30c. So it's best to have two thermometer to counter check each other and the heater.
Good on you Dr.Loh. Kee it up. Thank you for the info. 👍
I have the same problem with that exact digital thermometer I bought from eBay. They all seem to be faulty since I bought 2 more from a different seller and tested it with a glass thermometer; they all read 10 degrees off. Avoid these digital thermometers online everyone. I bought the same model at my local Petco that works and is accurate.
change the battery.
SlickChick How would changing the battery resolve it if it turns on just fine and shows the incorrect temp?
your vids r always appreciated man
This helps thank you
I use an Inkbird temperature controller (About £25 on Amazon) on all my tanks for that reason. Then just set the heaters a couple of degrees higher, but still within a safe range for double protection. They have a high or low temp alarm as well so you'll get a warning if your heater fails.
Would appreciate if you can make a video how to treat fish diseases (norm diseases) step by step ? Thank you!
Great video. Well I learned to not trust me heater or thermometer. After my incident too I have two thermometers + my heater
If owners tap water is that low of a pH, he should keep discus instead of battle his pH at every water change.
Or use something to raise ph like cichlid salts
Buffer is easy to use and very stable for Africans
Tim G I keep discus and I still have to use alkaline buffer just to bring up the 7.4 ph that the discus were raised in. It’s not hard to do. Just measure and add. Happy fish keeping.🐠😀
Marty Borst holy cow, what is your pH out of the tap! Well water?
My water measures 6.0 out of the tap. Even with my discus I have to use alkaline buffer to bring the ph up to 7.4 ph which they were raised in as I already mentioned. It really isn’t a big deal. I have to use alkaline buffer with all of my aquariums. I love my fish so I deal with it.
Hi Dr Lou, just a suggestion on a video or a series of videos discussing subjects like live feeder fish are bad, how to properly set up QT, fish diets etc. I know you are busy but people listen and to hear your advice
That Back Tank is heaven to fishes
Hi Doctor! can you make a video about the growth of the flatworm planaria, the cause and effect to the fish and also how to get rid with it. thank you so much and keep making good videos. HAPPY FISH KEEPING!.
Hi doc. I'm a fan of your videos. Very informative. Will you be able to post a video about neon tetra disease and why there is no cure for this neon tetra disease
Superb Sir. Please put videos about Flowerhorn diseases and treatment sir
Hi Doctor Loh, I was wondering if you would be interested in making a video about fish obesity? I was watching one of your past videos where you dissected a goldfish and showed the fat deposits. I think overfeeding is very common in pet fish and was curious about the direct effects it could have on fish health (not in terms of water quality) and if overweight fish can have heart problems and decreased fitness like we do. I know goldfish and koi will eat forever and can get huge but do they get obese? And does excess fat increase their morbidity? Kinda weird question but it's stuck with me.
Your video is very helpful for studying.
I want to study more deeply. Please recommend the book you used to study.
I saw your video on parasites Dr. Loh. I have a figure 8 puffer who had a long white string on both his fins I haven’t seen him poop white stringy feces. I noticed he’s not really eating and surfing the top of my tank but my other puffer has normal behavior and healthy.

Ok for sure my fish died unfortunately before I saw this I tried API general cure it didn’t work though. Thank you
Your awesome
I had an Angel Fish start to swim nose up..it got to the point it was nearly vertical. After one vid of yours I tried deflating the swim bladder...didn't hurt the fish...but did not cure it. I did notice doctor that this male Angel only ate only one food- flakes. Ignored all others. As last resort I bought dried krill at the local Asian market. After soaking them soft..I put them in. Both he and the mate seemed to slowly get used to the taste..then took them in regularly. That male seems to have 90% recovered. Malnutrition might have been the cause. I feed a wide variety to various fish in a 240 gallon aquarium..but no live foods. Only that male Angel would only eat one food exclusively. " Angelfish nose up" might be caused by several problems,malnutrition just one?
Malnutrition might make for a video?
Hi Dr Loh, I have a new pond setup without a proper nitrogen cycle established and I have to put 20 of my Koi fish. I have 1 pressurized pond filter pump and 1 canister filter running and yet I still have Ammonia and Nitrite record at 0.25ppm with pH8.5. My pond is running for 3 weeks now and I have reduce feeding to once every 2 days and perform water change daily at 20%. I have also added beneficial bacteria on every water change as well stress coats for Koi fish. Is there anyway to increase the nitrogen cycle for bacteria to take care of these Ammonia and Nitrite? Many Thanks
One of my iridescent shark seems to form a tummy and also started having bubbly eyes. What should i do?
Is it sick???
I love the dog in the background 😂
I think my flowerhorn is sick... its not eating now for three days its pink coloration is fading turning white. and its staying only at the one side bottom of the tank...
I had 3 of those same cheap ebay thermometers only one of them was anywhere close to accurate
I also request what Salamander requested. I specifically have an 8 inch Comet goldfish and he has lived alone for 8 years. Friends keep bugging me that he is lonely so I decided to get him one or two buddies. He has a 55 gal now but will live in a 125 with any buddy. I will need to quarantine his new friend and I would love your quarantine advice also. Thanks! Always wait impatiently for your videos. Cape Cod, Ma. USA
There IS some controversy over whether or not you ACTUALLY need a heater, but you certainly do if you live in in cold climates. I personally, don't trust heaters even one that is proved working if i don't actually need or it or the benefit isn't significant enough for me. I live in a very hot area, and room temp is fine. You are of course setting something up that is electronic with heat inside you tank, this can be an obvious nightmare, for one it relies on electricity so fluctuations could be deadly if it somehow malfunctioned or didn't work as intended/ fried/overheat your fish. Fish def prefer certain temps though.. it's more ideal but again it's a trade off, as you are relying on this device to not function as if it ever did could be catastrophic. Another time I'd certainly use a heater is if fish is sick, to help boost it's immune system while also helping any digestion problems that may be present. While filters, box filters, and alike rely on electricity, if they ever failed they would not harm your fish provided that the power doesn't stay off for a prolonged period. It's for this reason, I am cautious and hesitant with heaters. If you do get one, make sure it is reliable, accurate, and have more than one way of measuring the temperature, at least a stick on thermometer, and ideally have a way of alerting you if things go wrong, cause it definitely is possibility. proactive approach is the best way.
Sir please make a video on how to make a under water filter,which i mainly notice in your several videos like flowerhorn's swiming fin white spot video treating one... thanks a lot....
If those eheim heaters are not calibrated right they may not turn off at the set temp,. I had mine also overheat my aquarium. Then i switched to a fluval digital one.
Hello, my 4 months old sone gold fishes are not well , no swimming and no eating. What should I do please? Thank you.
The entire reason I don't use digital. My thermostat and analogue thermometer read the same. As long as that happens, then I am ok.
Thank you for the video. This is the reason I dislike heaters so much. I wanted to ask why did you not test nitrate? I assume you knew for a fact the tank had cycled.
It was a water temp issue.
Can you make a video talking about stunted fish? How their organs might grow if kept in a smaller tank.
What is the most humane way to kill a fish that is suffering ?
Poor fish...this is very sad. They were almost cooking inside the tank.
The fish tank (and thermometer) is right under the air conditioning . Probably why it was cooler on the one side .
With the extent of filtration, tank had a very high water movement, it shouldn't have affected the thermometer function. The ice pointing trick confirmed a faulty thermometer
The dog in the background looks misrable 😂😂😂
WOW I have never even seen fish survive at that temp. Also you just reduced their temp by 9C - that is a MASSIVE drop.
no. he reduced it by 3 degrees C. from 34 to 31. hoping to reduce it down to 27-28 over the next few days.
Can you please also make a video on the effects of hydrogen peroxide on fish health?
Invest in a good, calibrated thermometer guys, your fish will thank you
Hi,
Want to share my oscar fish photos with u, its been with me from 2 years but now no movement only gasping, zero movement lying,

Needed your help, my arowana is not eating for 11 days.
At day 2 tried Metrogyl first , but didn't work.
At day 4 we tried to deworm the arowana with the medicine called "worm-out" and still didn't work out. We provided the arowana with its favourite food also.
At day 8 we tried using Tetracycline for the arowana but still it didn't work.
Conditions are worsening day by day.
My arowana is free floating over the water and swimming.
It is also becoming like a arch and not swimming sometimes.
It has become very weak .
Sir, please help.
It is a request please help and respond to us as fast as possible sir.
Tank size: 36inch length/18inch length
The fish tank needs more 🌱 plants.. it’s just as the sad decoration of the house… plain, brown, white.. fish and dog are sad

Could u plz guide
Hello doctor, I'm Khanh and me', from Vietnam. Next year I want to entrance exam to the university of medicine and pharmacy(they do training in veterinary medicine), and my score of Molecular Biology (we study Molecular Biology in High School in Vietnam) is not very good. And I wonder does Molecular Biology is necessary for a vet?
Veterinarians draw from a lot of different sciences, and molecular biology is one of them. You're best checking with your universities, their requirements. During my time here, subjects that were helpful were chemistry, physics, biology, mathematics and English. Good luck!
I have that Eheim heater and had the same issue with it!! The dial on the heater is almost 10 degrees off.
The heater and its thermostat worked perfectly. The problem was the thermometer.
You can re calibrate those heaters. Also they can be taken out the water while on as they stop heating up.i have 3 of those heaters.
You said 50g of something. Was it a commercial carbonate hardness buffer or just sodium bicarbonate?
sorry to bother u again so i didnt do a creek pond i have a good bio filter but my question is once in a while ill see a couple fish flash i did a scrape and found nothing im getting aggervated please help also there fins are flicking

You said 50g per day but not what to use
Hi dr. My betta fish has a problem and I dont know how to help him. Hes up on the top water and throwing air bubbles out of his mouth. Can you please help. Thank you!
His skin is doing well.
Key bases for not killing your fish:
1) correct liters + companionship (or none) depending on the FULL GROWN fish and it's needs
2) water conditioner + filter + heater/cooler (if necessary)
3) CYCLING the tank
4) nitrates, nitrates and ammonia: keep them in check!! Nitrites should ALWAYS be at 0 AFTER the tank cycles
5) the water surface needs to be moved by the pump to oxygenate the tank
6) QUARANTINE EVERY ADDITION!
If you have any questions, fellow viewers, just ask :)
I have a discus swimming erratically. He is literally doing laps around the tanks so fast. I need help please. All of my parameters are good so I'm thinking he's sick.

Wow, it's interesting that the owner never thought to check that the thermometer was right. I keep in mind that both the heater or thermometer could be malfunctioning and my biggest tank is only 70L.
I just set up a 36L planted tank and none of my plants want to stay planted, they keep floating. I'm using plant and shrimp formulated substrate. Anyone know what I could do to fix this problem?
It was a fully automated system for water changes and with the highly efficient filtration, you needn't have to ever stick your hand in the tank. This is how it was missed.
@@thefishdoctor8746 I guess that makes sense in such a large tank.

Those thermometers are about 5 bucks. I have one. I wouldn't be trusting them with that tank.
doc maybe u can help i have koi ponds and i wanted to make them creek fed and make them all natural if i do that would i have a parasite problem please help
you need a step filter bed. pump the water from the creek into progressively finer filters, pouring down from one to the next.
at the end, before it goes into your tank, you can have it pass through a diatom filter or a heavy UV irradiated box if you really want to make sure nothing gets through.
of course, this is hardly "all natural", but it's the only way to avoid microbial contamination, if that is something you are concerned about. You would still have the advantage of a well balanced mineral content in the creek water supply. probably. make sure you also source the creek water so you know what it passes through before it gets to where you want to pump the water from. just because it's natural, doesn't mean it's really good for fish.
That said, I have had many flow through aquarium systems both fresh and salt water, and have never had a problem with parasites. just basic rough filtration (water is pumped through standard filter materials like "aquarium wool" to make sure any debris is removed while it is heated/cooled to the proper temp before entering the aquarium proper.
I have a question for anyone who’s had this experience. In the past, whenever I added new fish to an established tank, my fish die. Not the new fish, but my older ones. It’s been years since I tried, but it always happened despite my being careful where I bought the new fish. My fish will usually die within 3-7 days. Here’s the big issue. I currently have a Cosmo goldfish. I’ve had him for almost 10 years now. I would love to add 1-2 goldfish to his 20 gallon tank, but am so scared to lose him, yet it makes me sad to have him spend his life alone. Especially since he can live for many more years. He’s been alone now for about 5 years. Has anyone experienced this or have any advice I can try. Thank you in advance. I asked my local pet store and they said they never heard of this happening.
I've noticed that too. New fish..somehow seem never these days to be 100% healthy..and its only days later years old fish come down with something. Didn't used to be like that. Modern times. Keep some kind of all purpose medications on hand. Like Kordon Ich gone...with formaldehyde and methylene blue seems to help a great deal. Wont harm plants also is a big plus.
@Cunning Stunts I only have one aquarium set up. I'm usually good at spotting an unhealthy dealer tank. But,when you do go weeks or months with no new fish? All it takes is for one new fish to sneeze...ugh.
If you were to inject a koi carp with antibiotics, were is the best place to give this

How to reduce or increase pH?
check you tube on how to reduce and increase pH.
What I do to maintain a stable ph in my guppy tank I added a big snail shell it doesn't let the ph drop even if I add soft/acidic water it keeps it stable. I'm not an expert and only have a few month of experience keeping fish but I do a lot of research and it helped me my guppies looked off and didn't know what was wrong then I tested the water and kh, gh and ph were low. You have to add buffer to the water or something like cuttlebone crushed coral in my case I added a big snail shell and it made such a big difference it only took a few days for my guppies to recover they were more active and looked much healthier.
I'll pay you to come here and cycle my tank so my fish can live because i am getting sad about my tank now my tank has ammonia and yeah i am Cycling my tank! And its harder then shit
We have mobile fish vets in Perth (WA), Melbourne/Brunswick (Victoria), Sydney/Bankstown (NSW) and Duffy (ACT). Internationally, we have fish veterinarians in London (UK).
That thermometer was made in China.
