Catch the fish give by their bum a GENTLE squeeze and look at the holes, females will have 1 big one small, males will have 2 small. If the fish are immature and have not bred it is very difficult to tell unless you are good at it, good luck How big are the fish?

[Matto]

the biggest would be around 10cm and the others are around 5-8cm at a guess

Probably borderline for being very easy to sex at those sizes but you can always give it a go, when I am transferring fish I always have a look at a few vents of fish that I know the sexes of to try and get an eye in for it but it is still pretty hit and miss.

[Matto]

so should i leave it then and try when they are bigger?

[ryanjury]

I would give it a go if I was going to catch them or had a very good reason for it.. But probably not worth the effort of hauling a big tank down and chasing fish around to catch them stressing them out etc when you may not see an awful lot when they are that young.

ok thanks ryan
