BTA question

[brode]

So my BTA likes to deflate since I got him 2 months ago usually around the evening other than that he seems to be doing good. He is only about 2” in diameter when fully inflated so I assume he is a recent split. He eats when I have fed him and the clown actually took to him unlike the other 2 anemones that I have. Is this something to be alarmed about my other two don’t do this at all. This is the rock he came on and hasn’t tried to move at all.

It looks ok to me.

My Ultra Rainbow BTA does the same thing almost every night, once the lights start to dim it starts to deflate/close up and as soon as the lights come on its back to normal, I wouldn't worry too much.

I have 2 Rainbows, different color morphs. 1 of them deflates every night the other doesn't. The one that doesn't deflate closes up totally though. They all have their own thing they do.
