Taxonomy
- Family: Callichthyidae
- Genus: Corydoras
- Scientific name: Corydoras kanei
- Author: Grant, 1998
- Current placement: Hoplisoma kanei (FishBase)
Habitat
FishBase records the species from the Negro River basin. Seriously Fish reports it from the rio Negro basin, possibly restricted to the rio Branco drainage, with the type material said to originate from Roraima State near Boa Vista, Brazil.
Tank requirements
- Minimum tank volume: 80 L
- Temperature: 22-26 °C (72-79 °F)
- pH: 6.0-7.5
- GH: 2-12 °dGH
- Substrate: soft sand
- School size: 6 or more individuals
- Lifespan: 5-10 years
Diet
The species is an omnivorous forager. Seriously Fish notes that it accepts sinking dried foods plus live and frozen items such as bloodworm and Tubifex, and that a varied diet maintains health rather than relying on leftover food or expecting the fish to clean the tank.
Compatibility
Corydoras kanei is described by Seriously Fish as peaceful and gregarious, requiring groups of at least 4-6 individuals. Seriously Fish notes it is easily confused with C. atropersonatus, distinguished by dark anal and caudal fin markings, numerous smaller body spots and a darker base colour. It suits calm community aquaria.
Breeding
Seriously Fish recommends a ratio of two or more males per female and triggering spawning with large (50-70%) cooler water changes and increased oxygenation. Eggs are laid on the glass or vegetation and hatch in roughly 3-4 days; fry accept microworm and Artemia nauplii.
Conservation status
IUCN Red List: Least Concern (assessed 2020). FishBase rates the species as having high resilience.
