Hello!
I am having problems sexing my S. petrii, not easy to lift him/her/it up and look on the underside... Is there any other way to determine the sex?
If you keep a group of S. petrii, is it possible to keep more than one male in the group (if keept in a large tank)? Or will the males fight? (Only asking because i have heard of people keeping several males in one tank... but i want more opinions.)
