All Fishes Data Sheet
Scientific Name	**Hoplisoma granti** (Tencatt, Lima & Britto, 2019)
Common Names	C020, Skunk Cory Arched Cory, Grants Buepansermalle (Denmark), Grants Cory, Stromlinienpanzerwelse (Germany)
Type Locality	Igarapé Ya-Mirim (= Iazinho), a tributary to the Rio Cauaburi, itself a tributary to the Rio Negro, São Gabriel da Cachoeira, Amazonas, Brazil, 0° 16'19"N, 66°38'21"W.
Pronunciation	hop lee so mah - GRANT aye.
Etymology	Named in honor of Steven Grant, who previously analyzed the differences among the arc-striped corys and recognized C020 as a distinct species (published in the Journal of the Catfish Study Group).
Species Information
Size	55mm or 2.2" SL. Find near, nearer or same sized spp.
Identification	The colour pattern forms an even arch of dark stripe from the snout to the lower back. Sometimes the cleithrum will have an iridescent gold or bronze color. Corydoras granti is very similar to Corydoras arcuatus. C. granti can be distinguished by having a shorter, more rounded snout, whereas C. arcuatus has a longer straight snout. Also, the posterior margin of the pectoral fin spine of C. granti has serrations pointing toward the spine tip, whereas these serrations point toward the origin of the spine (toward the body) on C. arcuatus. Finally, when full grown, C. granti is a smaller species than C. arcuatus.
Sexing	Females larger and fuller bodied.
General Remarks	Corydoras granti is very similar to C. arcuatus , and specimens of C. granti are often sold by pet stores under the name C. arcuatus. A key to the arc-striped corys can be found in this forum thread. See also Grant, S. 2014. Journal of the Catfish Study Group (UK), 15(4), 24-29. The name C. granti was first published in a description of a Corydoras similar to C. nattereri. See Grant, S. 1996. New Species of Corydoras or hybrid/variation? Northern Area Catfish Group. The usage was later described, again by Grant, as tongue -in-cheek ("jokey") and so presumably not evaluated as a nomen nudem.
Habitat Information
Distribution	Widespread throughout the Upper Amazon region. Amazon, Upper Amazon (click on these areas to find other species found there) Login to view the map.
IUCN Red List Category	Not Evaluated
Temperature	22.0-26.0°C or 71.6-78.8°F (Show species within this range)
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, and close to mandatory, substrate should be sand, but rounded gravel is an imperfect alternative. Avoid keeping over rough edged (chipped) gravel or sharp sand. This will increase the risk of damage to 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 a group of these fishes.
Compatibility	A peaceful, shoaling, community fish.
Breeding	Has been bred in captivity.
Breeding Reports	There is no breeding report.
