He hasnt been, but he he's definatly in the pecking oder in the tank. He's the second to largest fish and he's second in line, above the two 5-6" Dats. He does not nip or tear fins, but he will get his food first.
It looks like a female. I might be interested. I have three that are slightly bigger now. I was about to get rid of mine as well though.. I'll let you know in a couple of days, that's if it's still available by then.
