Cat-eLog Data Sheet
Scientific Name	**Corydoras acutus** Cope, 1872
Common Names	Black Top Cory Blækpansermalle (Denmark), Panzerwels/Corydoras - Catfish (Germany)
Type Locality	Río Ambiyacu, Shansho Caño, Loreto, Peru.
Pronunciation	kor ee doh rass. - ah KEW tuss
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 its pointed (acutus = pointed or sharp) snout.
Species Information
Size	65mm or 2.6" 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.

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.
Suggested Tankmates	Keep in a shoal of at least 6 individuals.
Breeding	Unreported.
Breeding Reports	There is but a single breeding report, read it here.
