Polyp Bailout - Last Ditch Effort by Stony Corals to Survive
HTML-код
- Опубликовано: 14 ноя 2018
- When it comes to reproductive methods, corals have a diverse skill set. There is however a much less common method: Polyp Bailout. Polyp bailout is a stress response to unfavorable tank conditions that certain stony corals can activate as a last ditch effort to save themselves. During polyp bailout, polyps are killing off their own connective tissue through apoptosis. I hope you never have to experience it happen in your aquarium, but it is something to be aware of none the less.

Polyp bailout isn't my favorite topic to cover, but it is good to be aware of these types of things when caring for corals. Hopefully you never have to deal with this in your tank, but if you do there is a chance the corals survive.
Than where do you get your your detailed coral information?
I'm putting together care information along with more indepth information that's searchable and sortable.
Tidal Gardens Well made. Very informative. Thank you for sharing your wisdom with us. 🙏🙏
Thanks for covering the polyp bailout. I have this happen to a hammer coral. This happened about 6 months ago. It has survived in my sump for this long. The light level is very low in there. My question would be will the grow an new skeleton?
Tidal, about a month I purchased 3 beautiful frags of torches for my nano reef, and I did aclimation for about an hour and coral bug dip. They looked fantastic for about a week, then one by one started to first lose color, getting into palid look, then polyps started to die. They will contract at night, but during lights they will come out a little, but definitely they’re not good. I started to do water changes in order to bring down nitrates I read they were present. After that, all my corals decided to get bad, and shrinked. I just have stop doing any to my tank. And after 3 days some Zoas started to reopen, not fully, but they’re half awake. I don’t know what else to do. Any suggestion?
John Holmes were u able to save the hammer?
Thank you so much for making these videos!!! Greatly appreciate all the insight and experiences you are sharing.
I just want to thank you for your videos! The care and time put into your videos is amazing. The clarity and focus of coral shots is nothing short of phenomenal!
Thanks for passing on valuable information & always in a professional , informed ,insightful manner. I’ve been following you for years. Listening to your knowledge which has help avoiding serious issues &lower the mortality rate and increase the time enjoying the aquarium thanks again Cheers
Blessed to live a time where we can zoom this close, excited to get to see the day where we can zoom in to the textures
I love your new and improved intro. . Top notch camera skills
Good video Than. I didn’t know this was a thing. Super informative, learned a ton.
Really like the intro.
Beautiful shot of the elegance
had no idea this existed. solid filming and production as usual.
Amazing video as always. Love it
Really really really good video Than.
Thanks Billy
I get the whole point clearly, very well analysis 👍
Hit the nail on the head. I had this happen due to salinity and it was because I had not calibrated my salinity checker for a couple of months. It simply escaped my busy mind and I payed the price for that. It took over a month for me to get the tank back to it's thriving self. I will never make that mistake again.
I had this thing happened to me about two years ago on my elegance. The entire polyp was swimming around my tank, no clue why that was happening. Thank you Than for the answer!
I like the new mini into, great touch, great info
Great video, thank you for the info!
Always very educational
I love your videos, so full of easy to understand useful information. You are a rare gem in our minefield of a hobby!!
Awesome video; very informative!
Fantastic video!
Great info. Thanks!
I’m sitting here multitasking reading an article about Acropora in Coral Magazine and listening to this video - I just realized you are the writer. I’m going to read the article again with that smooth voice. 😂
I'm everywhere!
another amazing informative video
thank you so much for educating us
Awesome video
Great video and lots of information. This happened to my current elegance coral . But now I know what happened and what to do to avoid it. Many Thanks, SUBSCIBED
I have had a lot of Euphyllias polyp bailout in me within one month. One wave op bailout happened right after changing the light (higher intensity) and the other wave happened after messing with the flow.
All the hammer coral I've had had polyp bail out. Conditions were stable. My frogspawn may be on the way to doing that too. I just don't know why I can't keep Euphyllia coral happy. All my other lps and sps are doing great. I'm at the point where I'm ready to give up on Euphyllia and focus on Acan lords and Blastomusa. Both LPS that have been growing new heads reliably.
Great video!!! I have to at least watch one a day lol. Would love to know the name of the LPS that is purple with the lime green inside? Keep up the good work love your online sales!!
Great video as always!
Legendary voice!!!
My dude!! your intro beat is so pimp and imagery even more so! Love you channel Than!!! Also love your dress for success look #coralboss
Excellent constructed video and videography. But you demonstrated polyp bailout as a stress event but it can be a means of positive reproduction. Would you be able to provide a video that demonstrates both forms of polyp bailout? One with and without stress events.
Your Videos are so nice.
Like RTN and STN is also a form of migration I think.
But more on a cellular level.
I had a sps go RTN a year ago, completely vanished.
Now a year later, I have sprouts of it growing everywhere.
Weird.
Awesome video :)
My alk spiked and my elegance polyp bailed out in the middle , redid my tank due to many issues it’s been around 4 months now and is still attached barely in the middle but is super happy .
I was just changing water and didn't get temperature right and saw Justin's ultra green Goniopora bail out. Temp of tanks was 79 before changing 8 gallons and went to 75. 1 polyp was in current and settled. May be one other.
Nice video enjoyed watching :)
I have had two of my euphyllia bailout and had no idea what was going on till now. I thought it was RTN. Checked my salinity reader and it’s out of wack 😩 thank you for this
While servicing a clients tank back in the 90's , I retrieved a "dead" bubble coral out of her garbage can and decided to bring it home and give it a go. Within a week the now healthy coral started spitting out baby's. In the end I got about 10 small corals over a 2 month period .A few months later I purchased a silver dollar sized plate coral from a hobbyist whose damaged "mother"" plate had been spitting out these baby plates at the rate of 1 a day for several months.
I am currently facing this issue, lost a few frog-spawns and hammers, I checked salinity, temp and nutrient no issue there only problem I see is low calcium at 380ppm. Which there was more information on this problem. Thank you for the video much appreciated.
Very nice vid👊👍
Thanks! Let me know when you guys want to go to Korean again.
Am having polyp bail out from my frougspawn it's been doing it now for a few months but all parameters are steady
The frogspawn you showed that ripped off from the Skeleton is the exact frogspawn I have giving me the same issue..
I have a colony of mushrooms and a couple of them are doing that but the other ones who are much bigger look very healthy so I don’t really know if I should move them or what. Also I don’t know what to think because I’ve never heard of mushrooms going through polyp bailout.
that happened to one of my hammer corals and not knowing that this was a thing I grabbed the head put it in a cup with some water and acclimated it for 15 minutes and then put it in my new aquarium and is doing just fine which is good but it is just shrunken up from being really stressed.
Made a good point about calibrating refractometers, I was off by a lot at one point. I thought it was at 1.025, after calibration it was now at 1.034! Every coral i put in my tank was ditching out and die. Luckily my fishes were ok.
This happened to me... Really disappointed. It was my first coral. A small hammer frag that was beautiful. I'm under the impression that it was getting too much flow and by the time I tried moving it to a low flow area it was too late... I might try again with something easier. Any recommendations?
had all my corals do this when my return bulkhead shit itself and the ammonia climbed to 1.0 fixed the problem and did what i could to remove all the anmmonia only to find all my greentips and other orals in the process of bailout any tips to save the frags would be great
I've got a mixed reef and keep having minor bailout with some of my *phora frags. My tank conditions seem to be spot on for hardness, alk, mag, havw awesome lighting, do regular changes with seawater and supplement. For some reason I keep getting these guys like to thin out. I also have slow to no growth with my other sps and lps. Do you think this could be chemical warfare with sofites (zoas/gsp/Xenia/couple of Kenya trees) in the tank?
None of my hard corals ever want to grow, and it's been going on a year.
It's a 50/50 mix of sofites and lps/sps
It is possible that they are experiencing some chemical warfare, but having said that I have a tank that is half SPS and half leathers and the SPS continue to grow. Is it possible there is a pest or harassment issue that is keeping the stony corals from growing?
@@tidalgardens hey thanks, I just now got the notification of your reply... freaking RUclips :)
I added carbon and upped my temperature from 78 to 81 to up the metabolism of everything and between the cleaner conditions and higher metabolic rate, that seems to be helping quite bit.
Thanks for the follow-up!
Just got a gold torch and on the 2nd day it started doing a polyp bailout
However now I see little baby polyps around the tank so I’m hoping for the best
Oh my god, I saw that 1 little polyp came off my hammer and i was soooooooo worried :(
I just saw one of my hammers come off too, did it get worse for you?? My whole tank seems happy but just this morning I saw a little hammer drift around my tank. And I was freaking out too
Do eyuphila do this when splitting? I habe a one frogspawn tgat seems to be doing this, but seems to be more concentrated towards the center of the head, not around the base. I've caught it doing it once before and thought it was too much flow but then upon further inspection realize it was just splitting.
Not when just splitting normally.
what is the white stringiness? my mushroom sometimes expels that but not sure what it is
Any recommendations what shall I do with my elegance and it has bail-out
Than did the frog spawn in this video live?
could feeding a elegance coral that's in bail-out help its chances?
@tidal gardens, what is the organism at 6:28?
Detailing with bailout now sadly.
I have an elegance doing this right now. I did catch the polyp and I have placed it on a rock where the flow is not real strong. Does anybody have any advice. I know the odds are against me but I be damned if I give up.
Thanks for the info, Than! So beneficial to new reefers. Question on budding for euphyllia: is that positive asexual reproduction? As an average, how long would it take a bud to actually grow into a decent sized head with extending polyps?
Budding is a very good sign of health in euphyllia. Particularly because it means the flesh extends down the stalk which is usually the first thing to die back if there are problems. It takes a few months for a bud to become a full sized head
Do fox coral do this?
Yeah, it has happened in my tank before. I have some new colonies that popped all around my tank... I taught it was normal.
I've had this happen recently to my candy cane coral. I suspect it had too much flow. One of the heads got caught in a recess in one of the rocks and is still there after a few weeks. Do you think it will survive and grow a new skeleton?
Any update? Did it survive?
@@MontysWall I guess not, after a while it disappeared (I guess got blown away by flow) and now it's gone
What type of fish at 2:01? I've been wondering what they are for awhile
Mandarin dragonette
I have a neon hammer doing this now! Half is hanging out. Is there anyway I can save it? Or just cut the losses?
I don't know. I just let it run its course and try to do things better next time.
@@tidalgardens Can the polyp regrow a skeleton when it falls off??? I saw the one in the video growing on the frag plug. Maybe just high hopes
So theoretically polyp bailout could re colonize a dead hard coral skeleton??
I guess I'm a bad coral parent as this just happened to my frogspawn that was doing great for the past 2 months and today found it floating around the tank. I did increase the flow slighty over the last month, but it didn't looked stress or hurting during that time. Guess it wasn't happy and now I feel terrible :(
It happens. I have a beautiful elegance coral that bailed out and the entire time was fully extended and healthy looking. Even floating loose it looked fine.
@@tidalgardens As only 4 months into this hobby, it's proven to be very stressful, LOL. But good to know that it does happen and that I'm not alone here. I'm sure one day I'll look back and say "why did I stress so much about that"
Thanks again for providing amazing information along the way!
1:38 acropora name ?
I think I just got a bailout...
This is exactly happening in my tank with pocilopora
pocilopora reproduce that way normally.
Whats the coral at timestamp 6:45 with the purple tenticles?
Did you ever find out? I am searching the comments for the answer!
@@Pastronomer69 tube anemone
What was the coral or specimen at 6:34 ?
That is a tube anemone. It's not something that does polyp bailout, but I was illustrating food in that clip.
@@tidalgardens I had a feeling it was some sort of anemone....it is beautiful that is why I asked
Couldnt you place this a month ago 😭😭😭😭
DogOlly tube anemone i think
👍👍
If the polyps that bailed out only knew they have to experience going through a wave pump and getting shredded, poor polyps😂
6:28 Ummmmm..... what is that? 😲
I will find random zoanthids growing in different parts of my tank from large colonies that I own. Is this a similar thing?
I don't think so, I think Zoas and soft corals can just frag themselves sometimes by just releasing its grip on the substrate. Stony corals that do this are pulling themselves off of their own skeletons.
👀👀🧠👌👏👏👏👏👊
I threw my refractometer in the bin they are garbage all of them I use a deep six and my second test is my deltec hydrometer the old fashioned way
My elegance coral is bailing out 😢
Who is part of the early squad!
🐶 🌈
e
This has happened to me recently. I bought a single head Rasta torch,paid a good amount for it. :( Love your videos,the most informative in depth conversations and cant wait to buy corals from you. my Wishlist is huge lol. Congrats on the new Farm looks amazing. @tidalgardens
