Crabs said:Thanks TT. Yeah I'm kinda afraid of the males going at it. I've been trying to breed my Regals for over a year. Today I got a deal on a breeding pair. So I was going to give my old male away if necessary. Sadly, they're identical in size and color. I would probably give the new 1 away by mistake (my luck). Mostly worried about stressing them with too many fish. So you answered my question. And I'll monitor the aggression between the males. Thanks again
