My tank has just about cycled through. Currently I have 6 Damsels, but once the tank is cycled I am going to get rid of them and get some nicer fish. I am considering getting a Lion Fish and I was just Wondering if someone could give me some advice. Should I get one? What fish would get along well with it? Do I have to worry about other fish being stung and killed? I have a 55 gallon tank. No live Rock. Thanks!
