Thank you. How on earth am I going to get a look at his/her anal vent? Is there a way to do this without stressing the fish out or taking them on a date?Gonna be hard !
Differential characteristics do not develop before it reaches 4 inches or about 10 cm long on this stage of its life fully.
By checking properly the part of the anal pore you should be able to note : a "U" shape if it is a female and a "V" shape if it's a male. Obviously, when aging males develop big hump.
Hope it helps
