I am getting tired of seeing post after post after post, of anemone after anemone being killed by powerheads, melting away, etc. Lately it seems to have increased. Anemones do not do well in MOST aquariums. Even the most experienced aquarists that keep them a few years, shorten their life considerably. Leave them in the sea. I read an article on this forum about a year ago. I tried to pull it up to post the link. I did not find it, however, I want you to type anemone in the search box on the upper right of the home page, and look at the rediculous number of posts relating to anemone failures. If you want that look in your tank, buy a Torch coral. Clowns will even host them sometimes. STOP KILLING NEMS!!!! Ok, I'm done. Any debate is welcome respectfully!
