Corydoras septentrionalis

Common Names: Longnosed Cory
Northern Longnosed Cory
Family: Callichthyidae
Category: Catfish_Bottom_Feeders
Distribution: America - South; America - South
Main Ecosystem: River; The Rio Guarapiche
Temperament: Peaceful; Though these usually peaceful fish do not harm most tankmates, they can become aggressive towards their own species and similar ones. As with many other longnosed cories, C. septentrionalis may fight with each other, tearing the opponent with their pectoral fin spines.
Diet: Ominvore; They will eat just about anything that fits in their mouths, but particularly relish frozen and live worms, devouring them with gusto.
Care: A hardy catfish, these cories don't require a lot of care. If they have a few hiding places (clumps of plants and driftwood logs are favored) and several friends (there should be at least six of each species of Corydoras in a tank, as they are shoaling fish), they will not be timid and hide all day. If they are not provided with the above, then the cories may well spend a lot of time in hiding. Keep in mind though, open swimming space is needed as well. These fish are active, and appreciate room

Potential Size: Male: 6cm (2.4")
Female: 6.5cm (2.6")
Water Region: Bottom; They usually only venture above the substrate to take in a gulp of atmospheric air.
Activity: Diurnal; Though they are normally daytime fish, they are somewhat active at night.
Gender: Females are larger and broader than males. This is especially apparent when these fish are looked at from above.
Breeding: This species has not been frequently bred, but spawning is most likely accomplished in the same manner as other Corydoras species. Slowly raise the breeding tank's temperature and begin doing water changes less frequently. The higher temp and dirtier water simulate the dry season in the wild. During this period, also feed the fish a little less, skipping a couple of days each week. After about a month of this, start feeding a lot more, giving these fish frozen or live foods. Once they have been
Comments: A wonderful fish species for a community tank. They are fun to watch, and will entertain with their antics. These catfish also help clean up leftover food that has sunken to the substrate. They are well-suited to the beginning catfish enthusiast, and to hardened veterans alike. These cories are set apart from most other species by their long snout, which gives them their name.
