Thanks Paul,

The third one is definitely getting to the clarity I am after.

Now if only I can get a calvus yawn (pic 2) with that sort of clarity ..... wub.gif

Hi Andy,

Yeah, that's a good article. There's no real easy way.

It depends on the situation you're given.

If you are growing a whole bunch, then you can safely assume the larger ones are males and the smaller ones are females. Or just wait till they pair up.

If you are going out to buy 1 or 2, then it becomes more difficult.

I always look at the breeding tubes side on (profile). Basically, thicker tubes are females. That's probably over-generalising it, other factors include age/size of fish, even behavior.

fins - feel free
