I would get them sexed again at 7-8cm.

Thanks kak.I can't sex them mate but you certainly are building a nice collection. Keep us updated on how all your plecs go.
Thanks mate, fish 1 is constantly caving and has done some strange things, the other 2 just sits under rocks.By head size/shape and the slightly hairy pectoral rays on the first 2 i would agree with those above.
Not really sure how old they are but I'd estimate them to be 1.5 years+very nice. I am hopeless with sexing but I can see the middle one is a male from triangle head and spiky fins. how old are they do you know?
I do notice that with my other hypans, so there is still hope for a trio but I would be over the moon with a pair.sitting in a cave does not mean its a male.
she might just want to hide. the males may take territory or even fight each other over a choice cave.
