It would help if they had been numbered on the picture so we all knows which ones are are looking at...but ok here goes:

I'm just looking at the first picture only:

The one of the far right looks male

Then the ones on the left, from top to bottom:

Female
Male
Male

That's my judegement anyway

Thanks i thougt that (photo 1) the middle a female too was.
Sorry for my bad english.

I would guess the middle one a female too, the rest i confirm according to plastic mac's opinion.
Plastic could you point out why you think the middle one would be male?

Looks lite female the one on the top to left.How big are they ?

They are 7 a 8 cm and the little one 5 or so.

Now i have numbered the picture.

I believe I agree with Plastic, all four are the same fish in each pic, correct?

I was looking at Foto 2, from the first post, and the one on the top left (in Foto 2) appears to be the same as the one Plastic picked as female. It looks to have a shorter snout than the others (for size).

She looks to be No 2 in the pic with the numbers (which appears to be Foto 1 in first post), looks wider in the body near the ventral fins than the others as well. As well as the ventral fins being not as developed (males use them to fan eggs/fry)

Ok, but i thought number two is a female too, because she lay higher
in the glass it looks like her her snout looks longer

Ok, females, tend to have shorter snouts. As having been explained to me and checking mine, maybe I'm not explaining it well to you. Harder to do in typing, but the eyes are further back from the tip of the snout on a male, and this is probably due to males battling for territory - to protect themselves. My thought was that '2' snout seemed shorter - not a whole lot, and I like side pics better. Look at the Home/Species info (scroll down that page) of this web site and check those pics. The female's nose rounds down faster than the male's. My female's look that way.

I would not be able to detemine why she is raised above the glass, or if it means anything. Just giving my opinion with what I can see. Hope that helps.

Ok fine. I will have a look and maybe i take some pictures of the side

nr2 is female, nr3 might pass as a female at first glance, but the pelvic fin looks too large for a female....

It might still show as a female though. You'll know for sure when they spawn

nr1 male
nr2 female
nr3 male
nr4 male

what numbers live in caves?

Females tend not to take possesion of caves. Males will fight over them if they find one they like.

1. Male.
2. Female.
3. Female.
4. Not sure but looks more male than female.
