Ok, it would not be a problem for me to have 7 females..

A breeder suggested 4 to be a female and 1 to be a male with 90% confidence, while the others are still to young (or the picture does not give sufficient information).

Any comment?

Hi,
My H.zebra are now 5.5-6cm.
Any idea about the sex (and what makes you tell so)?
Thanks,

Hello,

Thanks for your reply! In my present tank, I have ~15 tubes for 7 L46.

The question is: Would such a tank (60*40*35) be ok for 3-4 fish? And additional question: Is it ok to have "only" 3-4 adults in a tank?

Thanks,

Hi, I have 7 H. zebra which are ~6cm. They start to fight sometimes, and I was wondering whether two tanks with dimensions 60*40*35(height)cm so with a ground surface of 0.24 m2 would be sufficient for 3-4 L46 adults. I would split the 7 L46 in two groups to avoid too many fights. Thanks in advanc ...
