What is my Tatia?

[cory-ap2]

Is it really centromochlus macracanthus?
I perchaced with this name. But the clerk didn't know where it was captured.

How big is it? SL for

Centromochlus macracanthus

is listed at 2.8", which your fish looks bigger than (that's not to say the quoted size is right, it's just right for any fish seen.). Maybe

Centromochlus sp(1)

? Just the one fish?

[cory-ap2]

Thanks for the reply.
This is about 9cm and the body is gray with mixed yellow and not black. So I think it is not sp(1).Maybe Tatia nigra?https://www.planetcatfish.com/tatia_nigra　I think colors are similar.

Granted there is only one picture of

Tatia nigra

it appears the caudal peduncle is much thicker than your specimen as well as the actual caudal fin itself is a solid colour as opposed to transparent and molted like your fish.

From what I could see in the Catelog I agree with Martin, it looks closest to

Centromochlus macracanthus

Thanks catfishchaos.
As you said it has solid color tail. So this fish doesn't seem to be Tatia nigra.
I'm going to think it's a macracanthus. I wish I could see the type specimen.
