New BTA, shrimp encounter, struggling clownfish

[sharkodile]

I have a tank which I thought mature enough to give an anemone a shot, so I came home with the smallest BTA at the LFS. Unfortunately I had not considered that my peppermint shrimp may not be good tankmates, and immediately after the BTA got settled and started to open, the biggest peppermint shrimp went to town on it, digging into it.

If that fracas wasn't enough, my big problem is that one of my clownfish is now apparently sick. I think it might have eaten a fleck of anemone? But it's now weak, see video below: it got pulled into the flow head and after I freed it, it is just laboring on the bottom. It has to be connected.

Here's a video:

Please give me any tips you have. Thanks.
