Not the best pics can get more this weekend, any assistance on sexing, i have had fry from the group but never found the parents. Two always cave, two never cave and two some times do/don't hide away in there caves.... I'm thinking 2M,2F & 2???
Any thoughts?? Thanks!!

Mostly all females I think. In L134 it is rare for the females to have any roughness to the tail at all. Smoothies are girlies.
