what kind of cory is this?
I've had these fella's for about eight months now. I own a pair of them and they are doing great, always swimming about together and very lively. So no issues there. However at the pet shop I got them from they told me they were Emerald Corys/Catfish. So I always thought that was what I owned, however I recently saw a pic of a Bronze Cory and realized it looked exactly like my two corys. So I was wondering if anyone here could tell me what I actually own from these pics I managed to get of them:

I'd go with either bronze or emerald cory. But leaning more towards bronze.

That is indeed Corydoras Aeneus (a.k.a. Bronze cory).

I think is a emerald cory!!!!!!!

Emerald Catfish is described well under the Tropical Fish Profiles. You may be able to find out by comparing the descriptions for the bronze cory and the emerald catfish in the profiles.

They are nice looking fish.

Emerald cory. Note the high dorsal fin.
They do look a lot alike though.

This confusion is widespread. All due to using common names. Both fish appear under both common names here and there. But as noted in the respective profiles, they are different.

Judging by the dorsal fin I still think it's C. Aeneus. The dorsal on the Brochis has 10-12 rays while corydoras has 6-8.

thanks for the help guys. I re-read both fish profiles and I am leaning towards Bronze now. I did my best to count the rays on the dorsal fin, both seem to be 7 or 8 which would make them Bronze Corys instead of Emerald Catfish, which is what I thought I owned.

My previous post only mentioned the confusion. Guess I should have said that jeaninel is correct, this is without question Corydoras anaeus. All Corydoras species and all Brochis species are very distinctive with respect to the dorsal fin, you cannot possibly confuse them. The body pattern/colouring is near-identical which is what many look at, but it is the dorsal that distinguishes them. The Brochis dorsal extends farther along the dorsal ridge almost to the adipose fin, but on Corydoras it is much smaller in length along the ridge.
