I got a Melanaurus wrasse that is picking on my ornate leopard wrasse. For some reason he doesn't like that fish, but he's cool with all the other fish in my tank (no other wrasses). The melanaurus is slightly bigger and I have since then moved the Leopard to the refugium in my sump for safety. I'm trying to catch the melanaurus but he seems to be smart enough not to enter the trap I've put in the tank. Any suggestions that could reduce aggression or will i need to get rid of the melanaurus?
