Sexing Eretmodus cyanostictus Kasanga

[amiidae]

Hello, I am new here.

Back to the question.

May I ask apart fm venting, is there other external diff I may look to sex this Goby ?

I have 2 and they seem swim side by side fm time to time yet I can't really say they are 'paired'.

Thanks

If they don't harass each other they are a pair.

[amiidae]

Thanks.

Anyway, here's the fish.

[amiidae]

Well, no further guessing required.

[Klaus Steinhaus]

Eretmodus will share in care of the eggs. This could be the male doing his turn.
The only 100% sure way to find out which is the female is to actually see her laying the eggs

[amiidae]

Thanks.

What is important to me is to know that I have a confirmed pair.

[Lisachromis]

Don't forget, some fish will have females spawn together. Once you see the fish holding beyond 5 days, then you have a pair.

[amiidae]

Day 8 of the fry. 18 in total.

[Piotr Koba]

Photos of the parent fish are more than ok, but I can see no reason for stripping them.

[amiidae]

Thats because I have quite a few other species of fish sharing the same tank with the new pair. so reckon it will be safer to strip her fm the eggs earlier than later.
