I have three cool fish but when I try to keep them together they beet the blank out of each other. The one in the community tank doesn't seem to bother any of the other fish.
its a probable (sp?) pair females on average grow faster than males. so there is no 100% accuracy but they come from the same clutch and therfore are the same age and one is about half the size of the other. Again this is not a guarantee.
