Hey guys my LFS just got some of these in they are labeled as batrochoglanis raninus
yellowcat wrote: 12 Feb 2025, 18:49 They're definitely a Batrochoglanis species but probably not Raninus, more likely to be B. Villosus at a glance. A side view would be most helpful as caudal fin markings are distinctly different between the two species. B. Raninus tail markings are commonly clear with a dark black vertical band where B. Villosus one's are more evenly pigmented and with a less distinct pattern. B. Villosus are rarely imported compared to the B. Raninus being more commonly available and as a result bring much higher prices. Anyway, more photos please..
I agree. I see hints of the spotty colors of villosus on some. But is this a mixed group?yellowcat wrote: 12 Feb 2025, 18:49 They're definitely a Batrochoglanis species but probably not Raninus, more likely to be B. Villosus at a glance.

If the color pattern is more like a bunch of small brown or black spots that overlap to form the bands, they might be villosus or cf. villosus.

From looking at the bucket shot there appears to be a mix of males and females to my eye. The one's with big heads are likely males and smaller headed ones in proportion inclined to be females. Then much depends on condition as a recently imported fish such as an underfed female may have a larger head in overall proportion so not always an obvious indication as to gender but an initial generalization until either become a well fed specimen. If they showed up at my LFS and I had the room for 'em, I would buy just two, one of each gender based on sexual dimorphism as to overall appearance even if it's just a guess at the time, eh? One problem exists when keeping this species as they often won't get along with each other and aggressively fight, gender may or not be a factor, I don't really know. If you were to get two and find that they need to be separated, at least you would have one of each sex in different tanks and be able to observe the differences as they grow..

Do you think he would be fine with my striped Raphael?yellowcat wrote: 12 Feb 2025, 23:59 Country, region or river system would of course be most helpful.

Batrochoglanis cf villosus then.
