Silutichthys sp. & Pseudopimelodid(?) ID

[Fallen_Leaves16]

Managed to find a Silurichthys sp. at my LFS; been searching for some time and was rather happy to finally get one. Very small, but healthy and active; it's currently in quarantine with a few Badis badis. Not entirely too sure what the exact species is, though; was first supposedly labeled S. hasselti and later re-labeled as S. phaiosoma. Anyone able to provide a definitive ID?


The second catfish was an alleged South American import without any form of ID; I (along with a few others) had believed it to be a Pseudopimelodus species, but its distinctively odd body shape (almost akin to rheophilic catfishes of Southeastern Asia) and unusual traits (extremely reduced/absent swim bladder, abrasive patch of skin on the belly region, distinct midlateral line, tendency to "cling" to surfaces, low tolerance for anoxic conditions) has made me suspect that the fish is a Glyptothorax species. The fish was only sold under the name "Red Marbled Catfish" and no collection point was provided. Any ID would be extremely helpful; I currently have the fish in a 10G quarantine with a large sponge filter and a decently strong powerhead for water movement, and would gladly appreciate any information that would allow me to better accommodate the needs of the fish.

Sounds like the Planet Catfish kinds of questions to me.

Completely forgot about PC for a hot minute, thanks!

I would agree with the glyptothorax call and probably go with honghensis. As for the other I would have stuck with the first choice of hasseltii
PC should be able to confirm both though.

It looks like Glyptothorax rugimentum, real slope on that guy's head. These have flooded Malay markets recently, was labelled as Goonch. They were misidentified by the supplier. A lot of people have been fooled thinking it was truly a gooch catfish. Luckily the fish kinda cheap, but in my experiences Glyptothorax are harder to maintained than a goonch.

I've linked the PCF thread in post #5.

Considering how useless "common" names are...and how easily created by sellers and collectors...I think they are completely missing the boat if they don't try to sell these as False Goonch. Very cool-looking fish, and perhaps a worthy challenge for aspiring "Goonch-wannabe-keepers" like myself.

As long as we're at it...that first catfish would probably sell like hotcakes...to a certain type of keeper...if labelled as a "Candiru X Wels" hybrid cat...

Sad update: The Glyptothorax rugimentum has recently passed, most likely due to import stress and something that I did wrong regarding its care. I was unable to really get it to eat much; the fish would occasionally suck up a couple bloodworms but that was it; the fish was apparently very skinny to begin with when compared to other images of the species. I moved the fish to a 20G long with a thin layer of sand and some rounded stones; the tank was filtered with an Aquaclear 30 and had a strong powerhead affixed to the far right end. Gradually lowering the water temp to ~70 seemed to help with labored and rapid breathing. Honestly, the fish never really moved much at all and would sit at the base of a rock for most of the day. Not sure if that's atypical of the species, though. Parameters were 0,0, and 5 (ammonia, nitrite, nitrate) with a pH of ~7. Interestingly enough, none of the fish (a handful of white cloud minnows) actively attempted to eat the corpse or showed any interest in it, and the body did not seem to degrade at all for several hours. I ended up freezing the body in a plastic bag with some water; what should I do with the body? Probably won't try sisorids again unless I can source a good chiller.

On a side note, the silurichthys is ~99% hasselti and the fish is doing very well in a 5g with tons of leaf litter.
