Australian Dendrophyllia?
 

i saw a ad about these and by their look I'm assuming there a typ of zoa....my question is do these guys eat amphipods cause i have about a bagillion....hasent been a pop crash in 3 month....just steady growth....some are the size of cockroaches (exageration....but some are a pretty goodsize...better than a 1/4 inch easy)....need to get something other than a mandrin...

also....saw them advertised by Reef2go.....anyone heard of them?

Nope, Dendrophyllia are hard corals, not zoanthids.

Try to get a Chalk bass (Serranus tortugarum) for your amphipod problem.
