So my strategy was just to pull out the males for my bigger tanks where there’s a lot of space. But when I took out all the juvies I can see:
Pudgy bodies
Little iridescence (all their spines clearly showing)
Very little colour
What looks like a clear gravid spot on some of them
Rounded anal fin
In my last batch we had one obvious male who started to colour up by this stage. He is in the boy tank and he’s very clearly a male at 2 months.
This batch I have 12 females - is that even possible or am I missing something obvious?
For reference:
Photo 1: all the females in the ID box look like this
Photo 2: one of the females from the last batch of fry who jumped into the alien ship while I was abducting the juvies
Photo 3: the boy from the previous batch who looked totally different to the girls at 5 weeks.
