Hi guys and gals, today i got my 8 baby red terrors, i am so excited, but i was wondering if anyone can tell me, how big do they have to grow, before you can tell if they are male or female? they are about 1-1.5 inches at the moment. I am only new to this, but became obsessed with these fish from the moment i first saw them! if anyone has some advice to share, it would be greatly appreciated! cheers, Kel
