Is there a known high fin variety of Corydoras aenus?

Today I bought some interesting specimens of Corydoras aenus in a local fishstore. At first sight the tank was full of normal Corydoras Aenus, small ones. But at closer examination I discovered 2 fish in the tank which had an unusual and very high dorsal fin!

These fish were too intereseting to pass by, but the store manager looked very confused when I said I wanted two very specific individuals from that tank.... So he let me catch them myself:-) Because 2 is not enough for a happy Cory group, I added 4 "normal ones" too.

Anyone heard of or seen this kind of Corydoras aenus before?
I know there is a high fin variety of something that looks exactly like Corydoras paleatus (with a C-number I think?).

Is there any known variety of the same in this Aenus spec.?

See picture below. The fish is still in the plastic bag in the picture.

There is a type of long fin C. aenus available here, but it's the lower lobe of the tail fin that is elongated, not the dorsal fin. The specimen in your photo appears to have an elongated tail fin.

Since posting the question above, I've discovered that there are some known variety of these fish. I found some pictures on a japanese web site, and there was two types. One had both tail and dorsal fin long, and one that I thought looked just like mine; only the dorsal fin was long.

But....When I study mine a little bit closer, I can see that their tail fin also is a little bit longer. I didn't notice that at first, but compared to the normal ones there is a difference.(BTW: the "correct" name of the "tail fin"... is it caudal fin?)

This could be very interesting to watch while they are growing up .
Right now they are quite small, so their fins might not be fully develpoed yet.

Hi Mona,
That's correct. In case you're interested in more facts & names, go to the Help button in the upper toolbar and click Glossary and/or Catfish Anatomy
