Once again I need to pick some Corydoras nut brain.
How rare are the C.Undulatus, especially in U.S?
Yesterday I went to the local store and ready to buy those after I saw them week ago or so, and did some research about them.
Although I didn't find much information but at least so the pictures. And I thought they are really similar looking to C.Elegans.
How can I be sure they are C.Undulatus and not C.Elegans?
They seems similar, perhaps same family? Both seem to have similar coloring/marking. And both female are more dull and grey. Only the thing I noticed about the fish in the store was. They have this yellow/goldish small little spot on the top of the head in front of the dorsal fin. It seems I see this on the picture of C.Undulatus at the Cat-eLog of this forum. But it seems not showing on the C.Elegans. Also C.Undulatus seem to have more clearer(less marking) on their dorsal fin than C.Elegans.
Anyway, I was about to buy them but the lady works there told me that they are not C.Undulatus but they are C.Blochi. That really confused me since I didn't know what C.Blochi look like. So I came home without them and do some research. And I look the picture of C.Blochi and they don't look anything like that. And they look like C.Undulatus.
I think she confused since those are the 2 Corydoras name written on the tank glass.
So I would be appreciate if anyone know about them or how to recognize them in any way. It would be great if there are some easy way to do but I kind of doubt that since there are just too many similar Corydoras out there.
when I go there again. Especially the body shape.
