it seems to me that euphyllia are a coral that would pretty well beat the crap out of anything but other euphyllia, and the hammer coral is the one that i "need", so i am gonna go with the rest of the genus for tankmates. my lfs has just about all of them in the frag tank, so i can get them locally. the concern is not necessarily to establish a biotope tank, just things that will coexist and "look pretty" with each other. in my minds eye, this already looks like a beautiful tank. just gotta get my projector working
