Here are two of my Haits that my wife said are pairing up. i cant tell which one is male or female. the first pic is fish 1 and last pic is fish 2. im thinking fish 1 is female but thats a big hump for a girl. and fish 2 is male. they are about 4.5". i wont be home til friday so i wont know for sure. the pics she sent me arent the best.
