Identification This species has not been imported or photographed - it's something of a mystery. The holotype was supposed to have been lost but it appears it is in the Philadelphia Academy of Science collection. There's not much that can be gleened from it save for the fact that there would appear to be a band across the back like C. rabauti and C. zygatus, but like C. zygatus there looks to be a break in the band just below the dorsal spine. Also the holotype measures just 27.4 mm SL making it either a small species or perhaps a juvenile fish. The short chunky body shape also points towards being a juvenile.
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.

Hop to next section 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.
