I wasn't sure because I have the two 8 inch Electric Blue's and one is def female (laid eggs with the blue male but of course not gonna amount to anything) but it has pointed fins and I couldn't tell it was female till it laid eggs... I just put them with 3 other regular jacks that are right at 3inches and one has already started quarreling with the blue female over the cave the blue male resides in so... anyway glad its female! Blue gene Jacks!
