I am not familiar with this group. Belonoglanis tenuis is the best guess fm me.
Anyone can advise ?
Thanks. ben

Using Seegers I came to the same conclusion. That said, we may wait for others to chime in as I really do not have a great eye for distinguishing between the various genera of African twig catfishes (Belonoglanis, Phractura, Trachyglanis, Andersonia) of Amphiliidae.
Seegers points out, as I am sure you are aware, that they never live long in captivity.

What is the length of this fish?

Is this it's usual color /pattern so far...B.tenuis should be more uniform in coloration, mind you this fish is quite possibly stressed from being in the photo tank.

Another post on what I believed to be a B.tenuis from a few months ago http://www.planetcatfish.com/forum/view ... 13&t=27539

I would say there is two option which genus it belongs, either it is Belonoglanis or Phractura.
With Phractura dorsal fin is sited little bit more back than Belonoglanis. To find out the site of dorsal we have to see pelvic fin at same photo. From your photos I would say Belonoglanis. Also bony plates each side of the body looks more similar with Belonoglanis than Phractura. But on the other hand tail looks quite short and caudal fin looks a bit large for Belonoglanis.

At the moment I don't have better opinion about this. Do you have any photos from different angle?

This is a reason I was asking the size...these details fit to B.breini when compared to B.tenuis

Thanks for all the info/inputs.

Here are some other images.

btw, I noticed those tiny lump on the whiskers. Anyone know what is that for ?

cool fish but the ID will be near impossible i feel - are the lumps on the whiskers taste receptors?

I am going with

The sprinkled pigmentation on the body, dark on the fins, small size, the slender more delicate looking head.

I think the overhead shots such as what has been taken will be important in the future when it comes to telling apart the different genus.

Thanks for the input, Birger.

Any second opinion guys ? Thanks.

Trachyglanis Minutus might be a possibility but i think a belonoglanis species is more likely

In aqualog the head of what they id as B tenuis is very different - from above it is more rounded & from the side it is far less pointed - however who is to say their id is correct?

jippo · Post by **jippo** » 31 Dec 2009, 15:26

I would say B. brieni as well.

I was looking at Trachyglanis as well...the overhead drawing of a Trachyglanis ineac is very different looking than the overhead pic of this particular fish, this fish being more triangular and slimmer, the trachyglanis being more rounded forward of the pectoral fins. Mind you this is the only overhead drawing or picture in the book(Seegers) of any species from the family Amphiliidae.
