Scientific Name Corydoras blochi  Nijssen, 1971
Common Names C032, Spotback Corydoras
Type Locality Moco Creek near Lethem, 3°18'N, 59°46'W, tributary of Río Tacutú, Río Branco system, Essequibo, Guyana.
Pronunciation Kory DOOR ass - BLOCK ee

Size 60mm or 2.4" SL. Find near, nearer or same sized spp.
Identification Corydoras are identified by their twin rows of armour plates along the flanks and by having fewer than 10 dorsal fin rays. They are most commonly confused with the other genera in the sub-family, namely Brochis, Scleromystax and Aspidoras.
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.

Feeding Will accept a wide range of commercial foods including tablets, granules and flakes. Live (or frozen) foods such as bloodworm, white worm, grindal worm, Daphnia and tubifex are readily accepted.
Furniture Shade provided by overhanging rock work, arching bogwood, tall or floating plants are all that is required. 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.
Compatibility A peaceful, shoaling, community fish.
Suggested Tankmates All Corydoras should be kept in groups of at least 6 of the same species. Otherwise compatible with most other types of fish that are reasonably peaceful, as long as they don't see a Corydoras as a snack.
Breeding Unreported.
Breeding Reports There is no breeding report.
