The "fat" fish in the middle (facing left) of the first image has the body shape of a female. Beyond that is hard to say, as the pictures aren't of a good enough quality to tell if the others are males or just immature females.

Actually, looking again on the second set of pictures, I'd say there's probably TWO females.

By the way, the ID of female is only 75% certain.

Thanks a lot!
I am happy as long as I have one male and female :)
But it is even better if I have 1 male and two females...
Now they will just have to grow a bit before trying to breed them.
Is it on the body shape you can see the sex? The females have a little more hip than the males?
Thanks

There are several keys that provide the determination of sex of the fish. Body shape ("more hip -> female") is one of those. Thick spine and odontodes on the pectoral fin, "hairy back" indicates male.

Do the females have just small odontodes on the pectoral finns? or do they not have any at all?

Small, often bordering on non-existant, whilst (dominant) males have long. And a sturdier pectoral hard ray too.

Thanks for your answer!
It is very diccult to see the diffence on mine. Maybe they are just to young. I believe i can see some small odontodes on two of them if i look closely on the picture. That could mean I have two males and one female...
Next comes the question if it is l201 or hyp. contradens :?:

Ones again - Thanks
