i have a few(about 12) Geophagus Brasiliensis' and i need to figure out which one's are males and which ones are females. is there an easy way to tell the difference. right now they are about 2-4" in length. if someone can either tell me how to tell the difference or if they can give me pics i would really apprecite it. thanks.
 
The sex is hard to tell as they are similarly colored. The male has a more pointed genital papillae while the female's is blunt and more rounded. The male is larger as an adult and it may also have a longer dorsal fin and show a hint of a bump on its forehead.
