[beak41]

hi there
i'm new here. i just started my tank (37 gal. ) about a month ago and everything was going good til today. i got home from work and had to do some tank work. everyone was fine, i had to melafix a mono and feed my anemone (a pink tip ). about a 1/2 hour later the anemone started to turn black/green and looked like it was starting to decay. a friend of mine said they do this sometime. did i do something wrong? is it the melafix? or do they do this?
let me know.
thanks beak

Hey Beak, I have a pink tip H. Malu, does the same thing. I am told the color change is actually the anemone getting rid of its poisons and excretions. I freaked the first time this too. I have not seen Melafix cause a problem with this anemone but my hard corals were adversly affected. I stopped the treatments and did a water change. It helped to bring back my open brain coral.
