Hi everyone! This is my first post on the forum; I'm hoping someone can help me out. I bought a group of cories from my lfs last week that were sold to me as corydoras brochi but I suspect they might be something else. I thought they might be corydoras gomezi but I'm not sure. Thanks much!

Looks like Corydoras Trilineatus http://www.planetcatfish.com/common/spe ... ies_id=508

leopardus?

Hi EmilyC I just bought these myself. They are C102... No name that I'm aware of. I paid £25 for my three.

They are so striking.

Here are my three.

Unless you happen to know that they came from Peru it is more likely they are Corydoras leopardus than C102. C. leopardus are fairly common in pet stores in the U.S. C.leopardus come from Brazil though.

Hi,

C 102 is not really seldom in the hobby, it is usually exported labeled as C. leopardus.
The corys of Stefan could also be C. gomezi, to me they do not really look like typical C 102.
The snout seems to be a bit too short.
However, this is more than difficult to say if you don't know their origin.

The only thing that's absolutely sure: it's not C. trilineatus.

Cheers,

Thanks so much for the help. I've looked up the various suggestions. The spots on leopardus look smaller and the images I found seem to lack the horizontal line. This is the photo I found- is this accurate? Are there obvious physical differences between c102 and gomezi? They look almost identical to me.
Thanks again so much!

Hi,

C and CW numbers are issued for corydoradine catfish which cannot safely be assigned to any described species or already existing number.
This can be because there are some significant visible differences or the origin doesn't match to the species that optically match.

C. gomezi is said to have a circular spot in the dorsal fin. But there are also some doubts if this is perhaps just a variant of C. leopardus.
According to the genetic analysis published by Alexandrou et al. it seems that we have different species whereas C 102 is very closely related to C. leopardus.
As C. leopardus or similar forms are very wide spread in this area (Peru, Brazil, Colombia, Ecuador) and you can never exclude for 100% that part of the museum material labeled with C. leopardus contains also C numbers like C 102.
It wouldn't surprise me that within what could be named the leopardus complex we have more species than just two. But finally ichthyologists have the last word, I'm just a hobbyist...

C 102 seems to have a longer and more acute snout and a more slender profile whereas C. gomezi and C. leopardus are stockier.
C 102 seems to have a more worm lined pattern like C. trilineatus.

I would say that the picture (by the way do you have the right to post it here?) shows a cory that is well within the variability of what is currently regarded as C. leopardus, but they also can also have a pattern similar to Stefan's corys.

Cheers,
