Scientific Name Corydoras(ln1) filamentosus  Nijssen & Isbrücker, 1983
Common Name
Type Locality Tributary of Sisa Creek, flowing northwards, Río Corantijn basin, 3°42'N, 57°42'W, Nickerie District, Suriname, depth 0-1 meter.
Pronunciation kor ee doh rass (lineage one).
Etymology Cory = helmet, doras = skin. In this case it was incorrectly used to mean armour (cuirasse) instead of skin in allusion to the dual rows of plates that run along the flanks of this genus. This specific epithet refers to the thread-like (filamentosus=provided with thread) extended rays of the dorsal fin.
Down arrow Species Information
Size 50mm or 2" 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.

Down arrow Husbandry Information
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.
Breeding Unreported.
Breeding Reports There is no breeding report.
