We purchased a long tentacle anemone about 5 days ago, and it is now dead. After we purchased it and brought it home, I did some research on anemones to make sure we acclimated them correctly and to make sure our water was in good condition to introduce him to the tank. We left it in the bag overnight because our nitrate level was WAY too high to put it in and I think this didn't help anything. But anyhow, he was fine in the tank for several days now, he crawled to the back corner behind a rock and hid. He was seeming to do ok, he was puffed up and all of his tentacles were full of air and he was looking good. Today, we went to check on him and he was all shriveled up and was like a quater of the size that he was earlier today :*( We have a Zoo-Med Light fixture with two T5 HO bulbs. 1 blue, 1 white light. We have a 56g tank, that is about 25" deep I would say. The odd thing is, this anemone went from looking great to like completely decomposed in a matter of hours and I figured he would slowly decay if he was going to die but it was like insanely fast. Any help or advice on anemones would be great. Thank you!
