The characteristics of CW28 are: Round snout; two broad, parallel longitudinal bands on the bony plates, one above and one below the midline; the dorsal fin spine has a conspicuous cream color. The maximum length is 6-6.5 cm (standard length without caudal fin).
CW28 has been known in the hobby since the 1960s. A specimen of CW28 was already depicted in the original description of Corydoras schwartzi (today: Hoplisoma schwartzi). At that time it was assumed that the animals with the broad bands could be a variant of C. schwartzi.
Later, this round snout was classified as a variant of Corydoras pulcher (today: Brochis pulcher), which is doubly confusing, as B. pulcher is clearly a long-snouted species, whereas CW28 is a round-snouted species. Nevertheless, the term “cf. pulcher”, i.e. “similar to pulcher”, was used for a long time (also in our stocklist). The coloration of CW28 is fairly constant, but there are occasional specimens with narrow bands that cannot be reliably distinguished from Hoplisoma sp. “Super Schwartzi Hifin”. CW28 is occasionally exported mixed with Brochis pulcher and Hoplisoma sp. “Super Schwartzi Hifin”.
