Uhh, not many anomonies are filter feeders. They will eat lumps of beef-heart or guppies. They DO eat fish in the wild, right ? >>I'm told that when adding trace elements and using the polyfilter > >I haven't heard about adding trace elements, I find this a tad surprising. Cobalt, Molybdenum, etc. all toxic in small ppm, but absolutely mandatory for life. In the right concentrations.

Yeah, specifically, it binds the ions and they sit in the substrate and *may* just stay there. But if the pH ever gets a tad more acid, all those copper ions are back in solution. Copper is best used in a BARE tank. -- Richard J.

I have not kept anemonies but intend to try in the future so I have been trying to ask questions. I've been told 2 things: 1) they are difficult to keep alive for more than 3 or 4 months in a non-reef tank system where you are using standard filters. 2) they are BOTH filter feeders and accept lumps of food and should be given both. Anemonies are a broad class of invertebrates so I guess Ill say I'd like to keep the kind that clowns love to cuddle up in (carpet anemonies?).
