Pangio is a widespread genus of small, eel- or worm-like loaches from Southeast Asia. Many similar species are traded under the banner of Pangio kuhlii; these are actually an as-of-yet unidentified species that resembles both P. cuneovirgata and P. piperata in various ways. Kuhli loaches are reclusive and nocturnal, although having a large group of them and plenty of hiding spaces make them more outgoing. You may not see your Kuhlis all day but they are known to go crazy when the aquarium is fed! Kuhlis prefer a soft substrate in which they can burrow completely, and act more comfortably and naturally in setup with such. They also appreciate thick leaf litter and sediment layers in blackwater-type aquaria.
This is an enimatic species of Pangio; thus far, it does not line up with any species we can find physical info on online. The closest match appears to be P. piperata, however that species has a concave tail fin and is slender, versus the convex tail fin and robust build of this species. It also resembles a patternless version of P. cuneovirgata, but lacks nasal barbels. Currently, we are not confident enough to even assign is as P. cf. piperata, so we are selling it simply as Pangio sp..
These are young specimens around 1.5" long.
