channa punctata

[agra113]

Hey guys i have 5 channa punctata fish. But the biggest ones are fighting the hell out of them. Any one know how to id male or female fish

I don't believe there is a distinction to be made on whether they will fight or not. If they are literally trying to kill eachother, one of the males might have found a female, in which case, he'll try to kill every other fish. (Also works the other way around, with females fighting cause they found a male)
