Hi I have a 30 gallon biocube and 2 weeks ago I added a lizard blenny. That and the yellow wrasse were the only fish in the tank. The wrasse has been there for about a year, when I added the blenny a couple weeks ago they started fighting a bit. Just pecks here and there. Now it seems like they are always poking at each other more blenny on the wrasse than the other way around. Should I get rid of the blenny my instincts are telling me they aren't working out. Any suggestions?
