it really depends on how much YOU like your corals.....you could put it in and nothing happens or it could wipe out everything. it is kind of like gambling. it is really up to you though, becuase if you know that you can catch it easily i would get it. another thing to take into consideration is that Pygoplites diacnthus can be wery difficult to keep in captivity. what size is your tank and how much LR do you have?
by the way, WELCOME TO REEF FRONTEIRS!!!!!!
