What's the sex?

[jamesfoad]

I have a zebra danio and I can't quite tell if it's a male or female. It is slim but looks like it has small silver highlights

Hehe that's hard to tell. Looks slim like a male, but more silver like a female. If you keep more you will more then likely have males and females. Males are thinner with more brilliant colours and females get chubby when they are ready to release eggs.
Not my image but the male is on top and the female on bottom.
