Could be. I'm wrong as often as I'm correct. That would be my second choice. We have no way of knowing if the original fish you saw were properly ID'd. A label on a tank can say anything. Just ask any of the people that have been buying a form of C. aeneus as C. eques, lately.Frank, if I may -- two more questions. Are you sure they are not C. brevirostrus instead? I see patterning in the caudal fin and the dot shape matches brevirostrus photos better (and they don't feel like melanistius that I've seen at the stores before).
That's a question that can't be answered as different folks have different success with different species. Both species have been bred in the hobby. There are no guarantees when it comest to spawning Corys. I have never kept either of these species, although I have imported both for commercial sales. Because there are so many spotted Corys and they can be so incredibly variable, I tend to keep only the most rare types. I'm a stickler for having all of my fish properly ID'd.The other question: How difficult are these to breed? Treat-them-well-and-they-might type or more complicated?
What does their caudal fin look like?
Differs from Corydoras melanistius by having patterning in the caudal fin. Was elevated out of subspecies status (then known as Corydoras melanistius brevirostris) in 2001.
Always happy to try to help. Cheers. - FrankHopefully you would not mind, but I may ask for one more ID in a couple of days... again a spotted species seen in a lfs, something toward trilineatus/julii/leopardus, but none of these. I'll try to get there with a camera.
