Peter – you wrote that it could be interesting to find out at what age its possible to distinquish sex in growing young ?
I took these photoes tonight of the small parvulus, – 🙂 .. well, they are really young but its quite clear to distinguish this one. I leave the whole photo unedited, because you can compare with the other fish in the tank beside (which by the way is also a young fish, not mature size)
They are so cute – the tiny parvulus.
Unfortunately its difficult to say the age, I wish I knew but I dont.
