BTA Shrinking Up

[jmc1024]

Hello all,
I introduced a BTA into my tank 2 1/2 weeks ago. Seems to be doing well, has nice color eating well and settled into a rock nicely. Over the last few days I've notice it shrink up twice, once on Sat and then again today. I've read that it does do this from time to time especially when expelling waste. It seemed to be doing so on Sat but didn't notice that today (could have missed it). Additionally, I have to clowns that haven't been hosted yet.

My question is, is this normal? How often do BTA's usually close up? Do we think that it's expelling wast, could the clowns be attempting to be hosted? Should I be worried?
Thanks,
Jay

It's totally normal, my three BTA's do it daily.

Since you have BTA's the only clown that will basically dive in them is a Maroon clown. With Ocellaris or Percula they may never go in. The BTA isn't a natural host for them.

My BTA anemone acts hella funny like that as well.

Totally normal usually at least one of my three closed up every night
