Nice! How big are they? The one is already developing a hump on his head. Looks like you could have a pair forming. Does the other one chase him around at all?

they all get along great one cut themselves on the driftwood but thats healing nicely they are good eaters aswell literly will eat anything i put in from feeders to pellets to even eating algae wafer same as my leis lol
