ID Apistogramma sp. colombia

[Zeufel]

Hi,

can someone say what this could be?
It's sold as A. sp. colombia. Unfortunately I only have this picture.

A. alacrina?

From what I can see of the fish in the picture, yes, A. alacrina. But a full body shot would confirm or deny that.

The photo is not good enough for any kind of identification. The best that I can say is that the fish belong in the regani-lineage, which includes the regani-, alacrina, and macmasteri-groups. That reduces the number of possible species to somewhere over 100.

I bought a pair(?) of these fish and here are some photos

No.1


No.2


Both

 

[Mike Wise]

Yes, they look like A. cf. alacrina Rotpunkt.

Hi guys, what do you think about the sex of this fish? It's the bigger one of the "pair", but I think its also a female. The fish are still juvenil.

Hi Zeufel,

I think the fish are too small to say for sure. I see signs of male and female. The second photo looks like a male to me, but on the other photo's I think it looks like a female.. How big is this fish?

Hi Mark,

i guess the bigger one (the one of the pics) is about 4cm.
Is the black/darker border in the dorsal fin a sign for a male?

Is the black/darker border in the dorsal fin a sign for a male?

No, on A. cf. alacrina, but sexes show black pigment on the first 2-3 dorsal spines. The same is true for the top of the dorsal fins on many populations of this species.
