Species profile
Hoplisoma habrosum
Common names: Salt and Pepper Corydoras, Dwarf Corydoras, Habrosus Cory

Salt and Pepper Corydoras is a peaceful South American callichthyid catfish recognised by a tiny cream-grey body with salt-and-pepper mottling and broken dark lateral blotches. It should be kept in a same-species group over fine sand in clean, oxygen-rich freshwater.
This dwarf cory has a compact body patterned with irregular grey-brown speckles, blotches and broken bars over a pale background. It is stockier and more bottom-oriented than the similarly small Pygmy Corydoras.
Identify this profile by the combination of a tiny cream-grey body with salt-and-pepper mottling and broken dark lateral blotches. Older sources commonly list this fish as Corydoras habrosus; the current profile follows the accepted or revised placement Hoplisoma habrosum. Colour alone can be unreliable in stressed, juvenile, or poorly conditioned fish, so body shape, snout length, fin pattern, and provenance should also be checked.
Mature females become larger, rounder through the abdomen and broader when viewed from above. Males remain smaller and slimmer, but young specimens can be difficult to sex.
Use a mature aquarium with fine sand, low cover from plants or wood and open areas for bottom foraging. Stable water and gentle filtration with good oxygenation are important because its small size leaves little tolerance for poor conditions.
Salt and Pepper Corydoras are peaceful, social dwarf catfish that spend most of their time on or close to the substrate. They become noticeably bolder and more active when kept in a substantial same-species group.
Keep at least 10 of the same species or coded population, with 12 or more preferred where space permits. A mixed collection of single corys does not fully replace a proper same-species group.
It is not territorial. Males may briefly chase one another or follow females during courtship, but sustained aggression is unusual when the group has adequate floor space.
Choose calm nano fish and other peaceful species that will not swallow or outcompete them. Avoid large fish, aggressive bottom dwellers and vigorous feeders that cause the group to hide or miss meals.
Soft to moderately hard, slightly acidic to neutral water is suitable. Provide good oxygenation and keep ammonia and nitrite at zero.

Manual aquarium siphon and gravel cleanerA manual siphon for routine aquarium water changes and accessible waste removal. The seller lists a hose approximately 1.6 m long.
Control the flow and keep the intake clear of fish and delicate planting. Clean the areas appropriate for your substrate and layout rather than disturbing the entire planted bed.
Offer small sinking granules, crushed tablets, gel foods and suitably sized frozen or live foods. Large wafers should be broken up, and food must be distributed so timid individuals can reach it.
Feed after faster surface and midwater fish have taken their share, and confirm that every individual reaches food. Use small portions once or twice daily, remove persistent leftovers, and vary prepared and frozen or live foods.
Breeding is achievable with well-conditioned adults. The female attaches adhesive eggs to plants, glass or spawning material, while the adults offer no care and may eat them; the small fry need clean water and fine first foods.
