Species Information
Size	49mm or 1.9" SL. Find near, nearer or same sized spp.
Identification	This species was described in 1872 with no picture or drawing and a couple of paragraphs of text. The author notes, "Straw color, with numerous indefinite brown spots on the sides. Dorsal fin with a large black spot covering anterior half, which also expands on the dorsal region round the base of the fin. Four vertical brown bands on caudal fin; anal spotted. Cheeks with blue reflections". In short, it should have no black marking in the top half of the dorsal fin and in particular the dorsal fin spine. Otherwise very similar to Corydoras agassizi.
Sexing	Females grow larger and are more full-bodied, this is best observed from above the fish. Males will typically have more pointed as opposed to more rounded fin tips as they mature.

Husbandry Information
Feeding	Will readily accepted all prepared foods that reach the bottom of the aquarium such as tablets, granules and larger flakes. Live (or frozen) foods such as bloodworm, white worm, grindal worm (Enchytraeus), Daphnia and Tubifex are readily accepted and good for conditioning groups of fishes for spawning. User data.
Furniture	Ideally substrate should be sand, but rounded gravel is an imperfect alternative. Avoid keeping over rough edged (chipped) gravel, this will increase this risk of damage the fishes barbels when it tries to dig. Substrate should be bordered with driftwood and aquatic plants leaving an open area for them to search for food and swim. The shade provided by overhanging rock work, arching bogwood, tall or floating plants are all that is required to settle these fishes.
Compatibility	A peaceful, shoaling, community fish.
Breeding	Unreported.
Breeding Reports	There is no breeding report.
