1 looks like a starberry peacock
2 some kind of mbuna i think
3 looks like a mixed yellow lab

would you know how to tell the sex

(1) is strawberry male for sure
(2) & (3) need better pictures to tell the sex

how can you tell he is a male

2 and 3 maybe females but really cant tell by the pictures

how can you tell i have heard that males have thouse spots on fin but someone else told me that that is not tru

im not 100% sure. but i believe females dorsal and pelvic fins are rounded. and males are pointy. and i think males do have alot more spots than females. female will have like 2-3 and a male will have 4+

I like the peacock!

thank you

ilicurtisili you are correct on how to sex africans.
