Female angle fish are smaller and have a round body shape where as the males are larger and more arrow shaped...they will pare off when they mature making it super easy to spot a breeding pare...they do not like to share the tank with anything once the eggs are laid they are very protective of them!
You're welcome. They kinda pare off on there own lol. They like to lay there eggs on a vertical surface like a piece of slate or broad leaves. When they become stressed they will eat the eggs to keep others from them. so it's best to separate the breeding pare once they pare off if you want fryOk that's very much will see what I can do to get them to pair off
