I found this catfish (only one in the tank) at the LFS, but it was marked only as corydoras. Not sure if it is even really a cory. All pictures are of the same fish. I have noticed that the dorsal fin is much higher/longer than my other cories and you can see that in the 4th picture (sorry for the blur, I just took these and this fella is a fast one). TIA

Hi!

Looks like C. paleatus "Highfin" to me...should be some forum posts about it here...

That is a peppered cory (Corydoras paleatus). Possibly a male at that, given the size of the dorsal fin.

I've looked over the internet and at the info linked to peppered corydora, and I don't think this guy is a peppered. All the pictures I have seen are small black spots and this guy has small and large spots on the dorsal and tail fins as well as the body. Also, all the peppered cories I have seen have large spots down the back and then another group of large spots running laterally down the midsection on each side of the body. The spots on the cory in the picture are not in any specific pattern, they don't run in straight lines at all.

What about a garbei.....link

I don't think your fish is C. garbei as this species appears to have a more rounded snout than your fish (plus much smaller spots). The color pattern is a little unusual for C. paleatus, but is not really that far off (the size and approximate placement of the spots are about right).

Your fish is possibly a Hi fin variation of C. paleatus, they are a distinct natural strain. The problem with C. paleatus is that until fairly recently almost all the C. paleatus comming into the hobby were fish farm bred and over the years the high dorsal fin has deminished through possible in breeding.

There are however two very similar species that have yet to be classified and your fish may turn out to be one of these.

The picture below is one of the possible new species.

I'm going to try and get some better pictures today. I went searching yesterday and found some "hi-fin" peppered cories (at least labeled that) yesterday for 8.99 a piece and got what they had, which was 4. I'll get some pictures of those in the Q-tank also, but from looking, the original doesn't appear to be a hi-fin (doesn't have the long-fins on the side) - Would they also need the side fins to be longer than normal to be considered a hi-fin or just the dorsal fin?

Thanks, TracyB

There are several different long-finned varieties of C. paleatus. I covered this in an earlier thread.
