Taxonomy & naming
This is an undescribed form: no scientific name, authority or type material stands behind it, and its identity and range are not documented in the sources the atlas uses. CW220 is a Corydoras World code, and the form is listed by Imperial Tropicals as Brochis sp. CW220. Brochis is a genus of corydoradine catfishes of tropical South America.
Morphology
Imperial Tropicals says the fish has the slanted black band of Hoplisoma melini, running from below the dorsal fin to the base of the tail, and the same black mask. The seller adds that the dorsal fin is clear rather than black and that the body is yellow rather than silver.
Habitat
Imperial Tropicals states that it was found in lagoons in the headwaters of the Rio Vaupés and was first collected in 2026. No habitat measurements are recorded.
Feeding
Corydoradines are bottom-feeding omnivores that sift sand with their barbels (genus-level); no diet is documented for this form.
Mating
Like other corydoradines, the genus spawns in the T-position, the female carrying eggs in her pelvic fins before sticking them to a surface. Spawning of this form is not documented.
Breeding
No captive-breeding record for this form is held by the atlas.
In the aquarium
Only one seller lists it, and the atlas holds no care figures for it. Treat it as a wild-caught corydoradine: soft sand, clean water and a group of its own kind suit the group as a whole.
Conservation
No IUCN assessment exists for this undescribed form. Its range and numbers are not documented, so its conservation status cannot be stated.
