about gumbo being a daddy that is (the fish in my av)... he never did build nests, but a couple of times.
i conditioned for 2 weeks on quality foods (no live though, i don't have any available except fry size) and daily water changes yadda yadda... ya know the right way to do it...
it's still way early in the game, i just released the female after about 30 hours, she is light bodied so i can't see bars or what not ... he has no nest and no intrest in her really. he's rubbed against her a couple times and flared a couple times but there is nothing going on besides that.
hopefully he'll get it... it is his first time, and hers too...
eta: she seems to get it - definitely showing submisseviness around him. clamped fins and head down. he just flared and nipped her, but doesn't seem to want to get to the nest yet. yeah, i know, i'm impatient! lol
