Do they start to get ornery or they get older and hit puberty? I'm starting to be able to pretty much tell gender on mine. They are about close to 6 inches now. And they have been having some scuffles.
The two (looks like a male and a female) get along great.
However they both don't like the third one (a male)much. They ostracize him.
