Corydoras Amandajanea & Corydoras Sp C143 the SAME species?

[bunthid tumnontigoon]

Hello! Again Everyone

I am really confused between Corydoras Amandajanea and Corydoras Sp C143. Are they the same species? Can someone really help me out? I have seen some information of Corydoras and they mention that they are the same species, but in my opinion I think they should NOT be the same species because of different patterns on their dorsal fins and also the tiny spots on their bodies. Can someone really help or Mr. Ian Fuller, can you really help me out? It will be greatly appreciated very much.

I have some in my fishroom, but I REALLY don't know exactly what species they are.

C. amandajaneae is from a tributary to Rio Negro and C143 is from Rio Tapajos, so they are not exactly neighbours...I'd say they are probably not the same species.

In my opinion they are totally different and as Kim says they come from the opposite side of the River Amazon and from totally different water systems.

If you are just looking at the colour patterns then there are several that are actually closer to C143 than C. amandajanea. C. ephippifer and C melanistius to name but two.

There are many many instances of theis kind of identification confusion and this is why it is important to have location details of the fish being compared, otherwise all that happens is even more confusion is created.

Thank you very much Kim and Mr. Ian

I am really appreciated that very much for all your information, but I really want to know what species I have right now or the most possible species that I have for my researches if it is possible. Can you please help? I also post some images in here. Thank you so much again. Oh! I almost forget. I got this species from state of Amapa, Brazil as the fish importer mentioned, but I have been researched all over from the internet and also from the books, those Corydoras species that I have, does NOT look like any Corydoras from that area. They look like Corydoras Sp C143 the most. Can anyone please help? It will be greatly appreciated that. I will wait for any information from everyone. Thank you so much again.

I would say my guess was spot on and you fish are C. ephippifer

Thank you very much Mr. Ian I really appreciated that very much, but Mr. Ian, I thought Corydoras Ephippifer from my study and my researches, its head shape should be elongated and slope down with short snout, but my Corydoras look like longer snout. And also on the dorsal fin, the black patch of the Corydoras Ephippifer extends ONLY onto the top of the body, but the black patch of my Corydoras extends through the middle of the body and also a little yellow line between the head and the dorsal fin or Corydoras Ephippifer has two different patterns as some Corydoras species have? I am still confused about that. Could you please help? I will be very happy if I know all my Corydoras are exactly Corydoras Ephippifer, so I do not need to think about this thing anymore. Thank you very much again Mr. Ian and I will wait for your reply.

One thing to remember with all fish is their patterns will vary from one to another, with some species it may be minimal and far greater variation in others.

And the head shap is also right.

I would still say C. ephippifer.
