Love the videos! Nice job
Hello Dr. Loh and others, today I’ve been searching the internet for any information on a certain physical feature that I’ve seen on a couple of koi. A little background information first: My town has a local park and in this park there is a spring that’s about 40-45 yards x 25-30 yards, with a waterfall outlet at one end of the spring. The spring/Park is also home to approximately 25-30 ducks.
I visit the park on a regular basis, especially after I bought a camcorder. During my time at the park, I’ve noticed two different fish (one a grass carp and the other some type of koi) that have sizable bulges on one side of their body, right in the middle. There are approximately 50 koi/carp in the spring. I’m pretty sure that the same grass carp has had a bulge for over a year. I noticed the koi with the bulge just a couple of days ago.
I wish I could say with certainty that a veterinarian makes regular visits to the spring, but I can’t. As far as I can tell, the koi seem to be healthy and happy. I certainly enjoy sitting by the water and observing these creatures. Any information about the big bulges, not lumps or bumps, would be greatly appreciated. Thank you.
very educational video. i will try to check body surface of koi.

Sir - I just want to know some ways to make my 4 King Kong parrot fish grow faster and healthier
(If it's possible plz make any video on how to do proper care of parrot fish )
Thank you for sharing. We don't have a fish Vet in the area. When my fish got sick, I was out of the element. Does API Melafix and Pimafix cover most of bacterial infection and parasitic/fungal infection?
Potentially they may work. The majority of my clients would have used these without efficacy, and called me to help.
This is so informative video which may relate to my situation. I have a small koi pond and I frequently have kois die-ing through illness and I am not sure why to do. I have tried so many things like frequently cleaning the pond and water change but there seem be parasites in my pond where the fish body has been eaten out, redness in their skins and a slimy residue around my fish face, what can I do?
I am now even trying to create a bigger pond with better ecosystem bczu I love fish but don't know what to do to keep them living longer and healthy, can you advise please?
You'll need to employ the services of a fish veterinarian.
Can you recommend good brands of freshwater parameter tests? I'm having issues of accuracy with the big name OTC tests; one will say my nitrates are close to 40 ppm, while the other says 5 ppm. There are similar problems with my tests for ammonia, nitrite, phosphate, ect. Thanks

Hi thanks for helping last time it's work a treat but now treated me pond for white spot 3 days now how long does it take for the white spot to go altogether
It depends on water temperature and how you're treating. Watch ruclips.net/video/xn2EbgxDiZk/видео.html
Hi Fish Doctor. I have lost a number of fish over the last week. Sleeping fish sickness is what I am seeing the symptoms called. I have done large water changes daily, with Salting the pond. Salt dosage has been one table spoon to about ten gallons of water. I have been adding a wide spectrum Microbe lift as well. I took a sick fish to my local Koi expert. A sample was taken and put under a microscope. They did not find any parasites with 3 samples. I would greatly appreciate some helpful advise.
Hi, I have these same exact symptoms. What can I do for their fin rotting and gills?

Hello. I just got 2 20inch koi fish from someone elses pond for free. I have done some research and found that they definitely have anchor worms, but what else, i do not know.they are not as active and stay near the bottom. I wanted to treat the anchor worms and anything else they may have, but I do not know if I have to do the treatment for anchorworms seperate from any other treatments, and then In what order should I treat withmedications. If someone could offer a bit of experience that would be greatly appreciated.

Large in ground outside covered open air koi pond. Population count 28 buttererfly Koi majority 20 yr. Plus. Found large adult floating dead tonight.

Dear Dr Log. I have ten goldfish in a 100 litre tank. Nine of them are thriving but there's one little one who hasn't grown since I bought hir. The tank has had several water changes, has an abundance of plants and good filtration and airation. There are no signs of disease or parasites on this or any other of the fish. I'm considering checking hir mouth for one of those little shrimp looking things as one of them killed a fish of mine 35 odd years ago when I didn't know such a thing existed.
Other than that I guess it's parasite treatment, a salt bath and physical inspection with very fine needle nose tweezers.
It's quite odd. All the others are doing really well except for this little one.
100 liters is WAY too small for 10 goldfish. You're overstocked!
Well, perhaps you were right. The tenth died and the others are all now as big as my hand.
Sorry to hear about the 10th! If you intend for them to grow to their fullest potential, the general rule of thumb is about 40 liters per goldfish. I suggest checking out multiple sources online to find out more!
Okay I need some help here. I've had a koi and a goldfish co habitating for sometime now and out of the blue the koi has started flashing and scraping itself against things in the tank (been trying to handle this situation for about a week almost two now). I've quarantined the koi away from the gold fish in a separate tank in order to properly treat him. I've attempted to salt bathe my fish and use fish amoxicillin to treat any potential bacterial infections he may have since he scratched off a scale or two now. I mean I am not sure what kind of parasites/diseases he has at this point because he doesn't present any of the prominent symptoms to any one specific illness. Under his neck on one side it is a little swollen and he may have a very slight opaque coloration to his slime coat in one or two small areas. I've dealt with fish my whole life and I clean my tanks on a regular basis, keeping an eye on the ph and build up of fecal matter. I know it is not ick, swim bladder, anchor worm, dropsy, mouth rot, fin rot, or fish lice. Please help me out here, everything I've done up to this point has kept him alive so far but he doesn't seem to be improving.
Dino Rawr you'll need to get proper diagnostics to know how to handle this situation, and before it gets worse. This is because many clinical signs of illness presented by fish are not specific to any particular disease. I'd also refrain from unnecessary use of antimicrobial drugs. There is a global concerted effort in preventing antimicrobial resistance.
The Fish Doctor Thank you for the quick response and advice, I appreciate it.

Hi Doc, My fish are behaving really strangely. I keep finding them in the morning in the skimmer basket. I first thought they were hiding for safety, but now I think they are going in there and cannot find their way out. The bigger one goes and sits on the bottom of the pond when I get him out. I worry he won't make it if he keeps getting "stuck" in the basket. This is new behavior for the group of them. What do you think? Thanks.
Check they're not hiding from predators. May be safer to replace basket with something they can't get stuck in. Or perhaps they're too weak from some kind of illness, that they get drawn into the basket by the water current. If it's the latter, best get them vet-checked.

hi Dr! just a question, i recently set up a koi pond. about a week old. my kois were doing fine until i added some bio filter media. it was a mix of 12 diferent kinds of media. After that, my kois started flicking and have bouts of flashing. any idea how what happened? i have removed the media and did a 20% water change. do u know that the media affected the kois? im afraid they die

It may be due to what's known as "new tank syndrome". Please include water chemistry results particularly for ammonia, nitrite, nitrate, pH and KH when posting.
Hello Dr Loh & everyone. What concentration of formalin was used? Is it left in water for a week or do you treat daily with formalin? I appreciate your response ❤️🤗
Hi is there a way I can get in touch with you?
Hi! A few weeks ago weve introduced 2 kois to our fairly new pond. There were already some goldfish and a few gold ides in there, but in a 8000litres pond we thought we could definitly introduce some more fish.
Theyve been doing great so far, eating and growing a lot, although still a little shy.
However today inoticed both of them flashing, ive only caught each of them doing it once, and the water levels seem fine. Should I be concerned? The other fish are also doing good, and itd be a pain to get those little fish out of there to examen them, what should I do?
llama lady you should definately look further into that... They could have a parasite... Ask your local pet store for some pond medication and you can consult a fish vet like this guy... Also.. Do you add rock salt to your pond every now and then? It helps to some extent..
I already lost 20 kois... T_T also.. You may want to redo your filter...
Mark Aparri thanks for the response! Theyre still alive, And ive only caught them doing it a few times since, im afraid to throw of the biosystem with medication... especially since its an outdoor pond with plants in it (for both oxygen and filtration)
Also our filter is fine, it filters 8000l/hour, and all the values are great, pond is clear, no amonia buildup, no algae buildup, all other fish are fine as well...
Asking a local specialist might be my best bet :) thanks!
I wanna make sure the koi can live their lives to the fullest, theyre still small right now but I hope to care for them many years to come :)
llama lady you mentioned that you have an outside pond? Ahm... I've been consulting with a lot of koi breeders that the pond should not be rained on... As they said rain could contiain harmful bacteria.. Glad to know your kois are doing fine... Btw... Since im from the ph, we usually have DIYs as an alternative. For instance... Instead of carbon.. We put charcoal inside a net bag in our filter. We washed it first though until it does not darken the water. Also a friend of mine helped me setup the filter and even put oyster shells. Just thought you might need some diy tips.. Happy fish keeping
@@MarkyPlaysPH strange that it wouldnt be allowed to be rained on, where kois are bred (in japan) they live in mudpools that are definitely outside. Also I know many places where they are outside, including where we bought them (they are specialized in kois, travel to japan yearly to go buy them), so that seems strange.
Thanks for recomending your diy channel :)
Update on the koi: theyve completely stopped flashing, theyve about doubled in size, have great vibrant colours, eat well and are nice and active :) theyre also getting really used to humans and come eat out of my hand :)
Wer can we buy this meds
Good day sir., can i ask about the red spot solution for my ranchu gold fish., its still coming back.,

How to treat a discus fish having internal parasite and not eating food.
My koi where flashing. I treated with aqua prazi first. Now I am finishing out with Malachite Green and Formalin made my aqua meds called Terminate. I am hoping this stops the flashing and poor behavior.
Hope it's turned out well. If the condition persists, please seek help from a fish veterinarian.
The Fish Doctor It did the job. Koi are back to full health and looking like the show quality they are.
I am facing fish argulus problem in my pond can you give suggestion to me
I have been seeing a lot of "home remedies" to clear up some types of problems, i.e. minced garlic. So is there any truth to this?
I got young kioy fishes in my tank. My tank is 110cm length and 90cm high. But I need good advice to take care of them well and stay healthy. But I wondering why water in the tank not being clear? No matter if I use clear liquid but still not clear.
Try using a finer grade filter wool.
You need biological filtration (lava rock, porous ceramic tubes, bio home media) this enables (good) bacteria to form and keep a clear tank, although not fully essential as ive not always used bio media only sponge filter once and had crystal water, but its normal for new or recently cleaned out tanks to become cloudy for a short while, no matter how many water changes, mine has basically taken two weeks to become fully clear thats with two water changes, don’t over feed as this can result in cloudy water, also any rocks,stones,gravel will need to be thoroughly cleaned before putting in tank, use tank water in a bucket to clean anything out of the tank as straight tap water kills the healthy bacteria, only take around half water out max each water change hope some of this is helpful 👍

Hello, I have a 500 gallon pond with many goldfish and 2 Koi. The goldfish have started dying (so far 25), they look like they can't breathe, they stop eating and eventually swim irregularly, like they pass out and come to. We have treated the pond, isolated the sick fish and treating them only to have them die. The gills look swollen and red, but i dont know if that is normal. We have changed the water, and included salt and beneficial bacteria. Any ideas before we lose all of our fish?

Hello dr Loh
Can a koi recover from a serious aeromonas infection without an injection? It’s being treated with bath salt and iodine only. No aquatic vet nearby and no medication available at koi store.
Thanks
How much formalin do you use my pond is 1500 gallons
There are several factors to consider when using formalin such as the fish species, severity of illness, the dissolved oxygen level, water temperature, the presence of organics, salt concentration and the parasites you're treating against. For a 5678L pond, the dose rate would range between 70-140ml. Remember this has to be pre-diluted and them distributed evenly over the entire pond. For more detailed information, we have provided in our newly developed and launched Fish Vet Masterclass available at fishvetmasterclass.mykajabi.com

Hello, doc! Good evening. I am owning 3 kois in my reftub. 1 blue skin, 1 kohako, and 1 doitsu. My doitsu has reds on his "skin" (coz he has no scales), and it's making an opening wound on it. I'm suspecting it as a parasite. I tried removing it but I couldn't coz doitsu's skin is so slippery and he keeps on moving whenever i try to remove it. He swims fine. He eats fine, too. But these red spots on his skin bothers me. I'm afraid it would infect my other 2 kois coz i'm trying to treat it for 2weeks already and still no improvement at all. What should I do? I badly need your help to cure my koi, Doc. I hope you notice this. Thank you!

Hi We have koi and gold fish and have been treating them with salt and Flavine. It’s two weeks now and their still flashing and some scales have fallen due to scratching them selves . The place that did a scrape said they have Costia . What should we do now.l?
Costia tends to attack the most debilitated fish, and so difficult to treat. A salt bath of affected individuals, followed by prolonged immersion of formalin of the entire system may work.
