synodontis

does anyone know how to sex them? is the male longer in the body and has longer feelers? and the female shorter and fatter?

just curious as i have just discovered that apparently they are now illegal to import to aus and i have a few of them in one of my tanks.. and its not illegal to breed and sell within aust ;)

A well conditioned female Synodontis will tend to be thicker and more rounded than a male, especially when viewed from above. Another way and especially Synodontis multipunctatus, is checking for the genital papilla. Many male Synodontis will show a well developed genital papilla anterior to the anal fin. When present, it is usually well developed, pointed and usually tipped somewhat to the rear. It is very similar to that seen on many male cichlids. Females of many species will usually show only a slight rounded protrusion in this area.

Cheers
