So a month ago I purchased a BTA for my tank. Being ignorant of lighting requirements ( had the 20w bulb that came with the 20g tank). Not surprisingly the anemone isn't doing well. I just upgraded to a t5 ho 24wx4 system and have it on a 12 hour timer. The anemone has been shriveling up on a daily basis before I got the new light and was exposing it's mouth and other white 'guts'? The anemone still looks bad and is likely on his way out. I purchases a blue decorator crab (with the big triangle back) and found him on top of the anemone yesterday eating it's 'guts'! Did the crab just take advantage of a dying tank mate or will they attack a healthy BTA as well? I don't want to try another BTA if the crab won't let it live. I've been feeding the crab pieces of shrimp and he's been hanging out in one spot ever since so maybe I should just make sure he's full! Thoughts? Thanks!
