Identification - C. agassizii & C. leucomelas

Post by snowball »

I recently got a group of corys from an online fish shop, they were listed and as C. punctatus but clearly are not. Upon raising this with the seller they conceded they were not the right ones and sent me another four which included one more of the same (C. agassizii?) plus three different (C. leucomelas?). That is the species I suspect they are but would value anyone else's opinion.

Looks like you might have either two Corydoras(ln8sc4) agassizii or one Corydoras(ln8sc4) agassizii and a Corydoras(ln8sc4) ambiacus, then two Corydoras(ln9) leucomelas.

Cheers, Eric

Cheers, I also wondered if one of the former might be delphax, I will try to get a photo of that one.

The possible leucomelas had me stumped due to the amount of black in the dorsal fins.

Hi @snowball,

I see no delphax there. Definitely not.

As to the leucomelas, yes there is some difference there, but the snub nose places both of those fish squarely in lineage 9, whereas the first two fish are definitely lineage 8, subgroup 4.

There are leucomelas-like c- and cw-numbers e.g., cw001, but they are likely all closely related.

Looking again at the first two fish, I think they are one Corydoras(ln8sc4) agassizii and a Corydoras(ln8sc4) ambiacus.

Cheers, Eric

Hi Eric, thank you for your help. I just remembered there is a proper forum for identification so I will post up photos of the individual fish there.
Cheers, Andrew
