In my rather limited experience, BTAs will only move around the tank so much. They tend to settle into any reasonable location. Careful not to confuse reasonable with optimal. I've had them hide out and start to shrink, requiring me to nearly force feed them to keep them alive. It may also be the case for your GBTA. Is it getting similar light and food to your other BTAs? So long as it still has color, things can't be too far out of wack.

how big of a tank are they in? the green one might be suffering from a little chemical warfare especially with it being outnumbered now. other than that: does it still take food? how often is it fed? is it shaded or out in the light? does anything host it? does it hide all day?

I have always read that the gbta are not as hardy as the rtba but I cant say from personal experience on this. Not sure why this would be since they are the same genus and species just different color morphs.

these are in a 40 breeder, i have 3 clowns in the tank so most of the time there is a clown in the anemone. I dont hand feed any of the anemones, it is in full light just not as high up in the tank as the others, it is on a rock that i can move, maybe i should try moving it? Would it be better to move it at night?

try shooting some frozen food in it when you feed your fish.

Is this true cyano - "chemical warfare"? For some reason I think I've seen these coexisting side by side with no ill effects...

Anemones can fight via alleopathy, but BTAs usually are happy with other BTAs because they are the same family. You can run carbon in a Phosban Reactor to help remove these toxins and help clarify the water, which then allows more light to penetrate to the corals and anemones.

@snakebyt do the clowns seem overly aggressive towards the anemone compared to the rose ones? and what are their sizes, typically you don't want a clown or a pair of clowns that is bigger than (I believe it is) 1/3 the size of the anemone just because they could stress it out with too much "love"

@blennyman in my own research on anemones when i was looking at getting one the last time I stumbled across several accounts of people stating that BTAs even though they are the same species they have slight differences in the "chemicals" they emit into the water column (I am assuming as a deterrent to keep other morph of BTAs away from their territory in the wild.) If you have two separate anemones in the same tank then I have read that there can be some warfare there, now if you have two anemones that split from one another they are the same anemone so they won't fight, so if you have two separate ones in the same tank and one of them split then the split anemones have the advantage of numbers.

Please keep in mind I am not claiming to know everything nor do I know this for a fact, I am just sharing information that I have stumbled across (I heavily read on every invert/fish/coral I even think about placing in my tank as to make an informed decision) I may try running some carbon if you don't already just in case and see if it helps assuming it isn't stressed from something else

well last night i moved the GBTA up closer to the light and near one of the RBTA, in this spot it will get more light and more flow as well. Ill give it a bit and see how it acts. Ill go tomorrow and get some carbon, i havent ran any in a while so it is due.
