Sexing S. Multipuntatus

[DragonKeeper]

Anyone have experience sexing these guys. I have about 10 that are between a inch and 2in. Is it to early to tell? How big do they have to be to tell?

Any help is appreciated

It's pretty hard to tell.

I just did a search and it is suggested that males have higher dorsal fins and females may appear "rounder" at the belly.
