Male or female?

[J19Reynolds]

One of mine is all yellow with small black line in her top fin and my other has black there but more and on his 2 bottom fins and light strips on his sides

the yellow fish is a lab im surprised we are even debating this look at the shape and colour guys. some have pale stripes.

the sex we cannot tell for either fish by the pics, sorry. the 2nd id assume female, however that's by the blue and it may be an immature male kenyi. the lab looks female to me but ur gonna have to trust your own venting x

Definitely a yellow lab, probably female but the second is for sure a female kenyi.

From trying to vent them there's only one that look female to me and Thats the biggest blue one... Others are smaller and harder for me to tell
