Psuedopimelodus sp. (1) ?

[goldcook]

Got this fish from an exporter, labelled as Cephalosilurus fowleri "Peru"
wrong ID I think

and than I search at pseudopimelodidae page
found that this fish really similar to

Pseudopimelodus sp(1)

, but i'm not really sure

btw, here are the photos






what do you think guys....

thanks

[Silurus]

I'm more inclined to think it's some kind of

Batrochoglanis

.

[goldcook]

ya... first time I check
I think its a

Batrochoglanis mathisoni

but my fish size is already 22 cm +

From a geographic perspective, I would expect that a fish with 'Peru' in the name wouldn't have arrived from the Caribean coast of Venezuela, which is the location given for B. mathisoni.

I've had B. villosus in the past that is similar, but different caudal. Fish exported from peru are not always from Peru,so mathisoni might not be ruled out. B. melanurus is also similar but comes from a place where I would doubt is being exploited by Peruvian exporters.I'd go for mathisoni.

Agree that Peru in the name doesn't prevent it from being from Venezuela - but it's a long way from the coastal rivers to anywhere in Peru, which makes me think it's more likely that the fish is from closer to Peru.

The other part is of course that there are another 2 species in Catalog of fishes. One of them is from the Maracaibo basin, where fish is very rarely in the trade, so it's a less likely candidate.
But Batrochoglanis transmontanus is listed from "Baudó, San Juan, Patia and Durango River basins: Colombia and Ecuador" could be a better candidate - but I have no idea what this fish looks like.

transmontanus is banded

hmm... Batrochoglanis family really similar to my fish
but, their max size are only 5"-6"
and my fish already 9"
so, I think its not from Batrochoglanis family

"

What may make a difference is the measurements in the Cat-eLog are in SL instead of TL which is total length.
SL is from the tip of the snout to the base of the caudal(tail) fin.

It sure looks like a species of

Batrochoglanis

to me.

[goldcook]

ya the one that I post is already 9" SL

from the shape and coloration
really look alike

Batrochoglanis villosus

and

Batrochoglanis mathisoni

but their max size is too tiny

[Birger]

The measurements we have are largest known...not necessarily the largest it could go.

More likely...it would not surprise me that there would be more undescribed/unknown species of

Batrochoglanis

.

ooww ic ic

would be nice if its really an undescribed species haha

My B. villosus was about 8 inches SL.

This pic is one of those random shots of misidentified pseudopimelodids you find on the 'net, if I recall it too was called c. fowleri-Peru but looks very much like the fish in question.

Here's a pic of a rare batrochoglanis I once had:

Your's is a very rare find, I've seen photo's of similar batrochoglanis and have been seeking one for years. I kept this unidentified species a few years ago and it is similar but mine lacked the large caudal fin and was more brightly banded although the banding at times would almost disappear depending on lighting/background and mood of the fish, common to some pseudopimelodid species. As much as the fish also resembles c. nigricaudus it is not due the different shape of of the mouth, much flatter as with batrochoglanis species as opposed to the inverted 'V' shape found in cephalosilurus. It is also very similar to the pic shown of the unidentified juvenile specimen collected by Dr. Sabaj in Venezuela. In any case with fish as rare as these, adult sizes are hard to determine as so few have been sampled in the wild. If it did come from Peru, I've found and kept some from there that are uber-rare and in recent years several new genus and species within pseudopimelodidae have been discovered and described by Dr. Shibatta in several countries so there's still some rather rare varieties that show up in the hobby such as yours. A fortunate find indeed!

yellowcat, the fish you had looks like transmontanus to me.

[grokefish]

I had one, there is a topic somewhere very similar to yours which I did maybe 2-3 yrs ago.

Here is video:


Please note the specimen was only in that tank for videoing he lived in a tank full o bogwood and plants.

Another point to note this fish was the most boring fish I have ever kept.it did nothing unless the lights were out, ever, even with moon lights it did nothing.
