What is attacking my BTA?

[pat_ask08]

I've had my BTA for a month now and last week, something started attacking it. I have 2 clowns, yellow tang, 2 skunk cleaner shrimp, 2 peppermint shrimp, an emerald crab and a couple scarlet hermit crabs. I've tried watching to see if anything attacks it but it must be at night. Has anybody had experience with any of these attacking a BTA?

I'd suspect a stressful demise rather than attacking...what is the lighting over the tank and parameters?

[pat_ask08]

All parameters are good. Lighting is a 4 bulb t5

There are pieces of the tentacles all over the rocks so I just figured something was attacking it

When they die they melt. I'd remove it from the tank.
Good isn't really an exact to help your issue.
How large of a tank?

[pat_ask08]

I'm not at home so I cant tell u exactly what everything is but I checked everything yesterday and it was all good. I have a 55 gallon

Well anemone are sensitive creatures. They need pristine, stable waters. It can take from 6 months to a year for a tank to mature enough to prevent these swings. This and a 4 bulb might not be enough light over a 55 for an anemone. What has it been doing? It couldn't have done this over night...
