I was wondering about Jags and there sex again. At the petstore there are inch to inch and a half jags and some are dark almost black and the other are slightly bigger but faded with a black stripe. Are the bigger ones males or are the darker ones? If it doesnt matter what do you think causes such a difference? I dont think that some were stressed and some werent. I was hoping i could have a better chance of finding a male with your help?
