To those interested in the fine, but admittedly boring details of taxonomy, the genus Crossocheilus differs from Epalzeorhynchus by rhynal lobes (nasal lobes).
Description ...
While there are some other fish (for instance many of the cyprinids) that have them, all catfish have barbels on the head: normally up to four pairs - one nasal, one maxillary, and two on the chin or lower jaw (mandible).
Pom-poms are a type of goldfish that have fleshy nasal lobes (enlargements of the nasal septa) that are greatly enlarged into pom-pom like tufts.
This catfish has 4 pairs of barbels; one pair nasal, one pair maxillary and two pairs mandibular. The jaws are described as having teeth arranged in bands. The teeth are described as being 'palatine'.
The pathway of the fish olfactory organ bears little resemblance to that of humans, for they do not have a nasal cavity imbedded in the middle of their skulls like we do.
Short rounded body, no dorsal fin, large, frilly nasal septa.
