i think marmoratas but the color is sorta resembling a perruno with its Small marbles..

thanks guys.

It's not P. perruno, there are too many dorsal rays. So, you have a young marmoratus.

k thats what i thaought.. just wanted more opinions..

i have 2 L. marmoratas.

After a fair amount of research I stil think these two species are the same. Certainly we do not commonly see perruno in the hobby. Nothing I saw in Venezuela convinced me otherwise...

Can someone show me a picture of a perruno then? Where the dorsal is not that big?

The few specimens that appeared at BAS a couple of years ago when they were getting Venezuelan fish were definitely different from the marmoratus we see usually from Peru.
Head shape, dorsal rays, everything about the fish shouted different species. I just wish I'd got some pics now. I did have a copy of Schultz that had information on Perrunichthys, but I haven't seen it for quite some time now...

OK, this is from the description that Pete gave me a loan of..

I only put the pics inline, the text you can read by clicking the links as I guess everyone doesn't want to download all this!

I also believe that these fish maybe the same species although my lfs has two catfish at around 20" they call perruno they have similar markings to the picture at the bottom of your original post.
i have never seen jevinile perruno only l. mamoratus and i think that your fish is mamoratus.

A lot of the confusion is down to TFH consistently labelling pics of marmoratus at perruno, and most dealers just used this name. It certainly sounds like this particular puzzle is something worth getting to the bottom of. I still think separate species based on the juveniles I saw at BAS, but I'd be delighted to be shown that these were just a population of a more widely distributed species.

im with Ceo on this one.. i have seen pics of perruno and they do look different then Marmoratas

Mike Littmann and John Lundberg will present a paper entitled "Review of the validity of <i>Leiarius marmoratus</i>" at the ASIH meeting in Manaus next week, which might shed light on the argument.
Be sure to watch for my running log of the Manaus meetings for coverage of this and other talks in the Taxonomy forum.

The correct name for the fish often identified as <i>L. marmoratus</i> in the aquarium trade is <i>L. longibarbis</i>. <i>Perrunichthys</i> is a completely different fish with a much more triangular dorsal fin.
