Great. Thanks for the confirmations. Always wanted one but was running out of space, except right next to my Frogspawn. I have an excellent coral specialist in town and they get some very nice hammers and now I'll be hunting for one. I like that 4th of July idea. May try that on a smaller scale.
-I assume their lighting & flow needs are the same as a Frogspawn? Is that accurate?
-I plan on mounting it on the vertical face of live rock, not the top? OK?
-I've read on this forum that the "branching"' variety is not hardy, even difficult to keep alive. Is this really the case? If so I want to avoid them and hope the manager can distinguish them. Comments appreciated.
