Holotype

Cat-eLog Data Sheet
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.
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.
Habitat Information
Distribution	South America: Corantijn River basin in Suriname. Guyana Waters, Coastal Rivers of Guyanas, Suriname Coastal Rivers, Corintijns (click on these areas to find other species found there) Log in to view data on a map.
IUCN Red List Category	Not Evaluated
pH	6.0 - 8.0
Temperature	22.0-26.0°C or 71.6-78.8°F (Show species within this range)
Other Parameters	dH 2-25.
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.
