i have them separated right now because one of them had taken a chunk out of the others tail. they are both about 4.5 " and can already see them getting wider by the day. they are both eating raw market shrimp only, they wont even touch a feeder even when i do give them some
nice rtc's. you can also try earth worms. they are like seriods for fish. i have 2 8inchers that i have to keep seperated also. they will calm down when they get bigger.
