I bought a RBTA the other day and everything was going well. it was big and happy. this morning i wake up to the rbta in a top corner of my tank next to one of my powerheads and i see little bits of tentacles everywhere in my tank. the rbta clearly got stuck to the powerhead, getting its arms ripped off. half of it is still there. will it survive? do i attempt to take all the little bits out? or is it safe to just leave it? i'm skimming and i just did a water change last night.
