Why do BTA bubble

[Daniel62]

I know that no one knows the reason, but I was wondering if you would post a picture of your BTA if it stays mostly in a bubble state and post your temp and lighting that you are using. Par reading if you have them. I am working on a little project and could use some extra data. Thanks

I can post a picture later from home but unfortunately what you will see is some nems bubbling and some not within the same tank. I have 4 T5s on the tank and temp is normally 79 - 80

Allen & Fautin state that the presence of clownfish caused the change but I'm not sure about that since I have seen BTAs both ways with and without clownfish.

I would rather assume it is due to light and water flow conditions and maybe also if it is looking to catch prey or not.

In photo you can see that 1 is bubbled and 2 are not

Irishdolphin, is the one bubbling, furthest from the flow, and does it stay bubbled the most. Do the clowns live in the other nem?

Thanks

I have several BTA..

1 bubbles.. all his splits would bubble.. then one day he moved and stopped bubbling for 5 months.. then he started bubbling again..

the others don't bubble at all..

4 t12 vho and temp is around 85 due to increasing warmth along the ocean due to spring and get the perfect temp for breeding clowns

I read some where that the bubbling is related to optimal light absorbtion

I think flow has something to with it. My bta split a few weeks ago, and the one that split moved in the path of my wavemaker, and keeps it tentacles shorter and bubbly. The original nem is near the bottom where there is a light and constant current, its tentacles are long and thin

It probably is furthest from the flow. The tank is a peninsula tank and is against the wall on the left hand side of the picture. There are 2 hydor magnum wavemakers on that side. One is one for 3 hours and then the other one. The flow travels across the top and side and then hits nems on the way back. Yep, it stays bubbled all of the time. The female clown lives in the top right nem and the male clown actually lives in the bubbled one

Best of luck with the investigation

I also think it has more to do with flow and lighting, in my 46bowfront the flow was a little higher and lighting a little lower compared to when I moved the BTA to my new 110 and they are a tiny bit closer to the light and a little less flow and they bubble like crazy now compared to the long thin stringy look it had in the smaller tank. Had the same clowns paired with the nem in both tanks.

Come on BTA people help me out please if nothing else, you get to show off your Nems

110g tank, LED lighting(40% white channel, 80% blue) about 3-4" above water surface and the nems are about 8" below the surface. Medium flow from two RW8's and the returns. Dont direct feed too often, but the clowns push bigger pieces of frozen food into the nems so they end up feeding pretty often. This pic is after the second split, the one on the right split again last night. They almost bubble twice, one at the base and one at the tip.

same nems but with different settings on my camera phone, thats the little male occ leaving the pic on the left and the female mocha top right

You can see sometimes the small bubbles at the tips go away and the ones at the base get bigger.

One of my main guys I order from has experienced that the smaller they are the more they bubble up. Same goes for when they get split. So far mind hadn't really bubbled up at all.

I have one rbta in a 28 jbj under a radion gen3 pro running at 35% .The rbta has bubble tips,but when it splits,the split gets moved to my 75 which is under 2 250 watt mhs.The rbtas have long stringy tentecles.So like everyone else it's a mystery.Maybe flow or light causes this.
