Introduction
The Salt and Pepper Pygmy Corydoras (Hoplisoma habrosum, widely known as Corydoras habrosus) is a charming nano catfish with a big personality. These peaceful, social fish reward a carefully maintained aquarium with plenty of foraging and interaction.

Species Overview
- Common names: Salt and Pepper Corydoras, Dainty Corydoras
- Scientific name: Hoplisoma habrosum (formerly Corydoras habrosus; also sold as Hoplisoma habrosus)
- Origin: Orinoco drainage in Colombia and Venezuela
- Adult size: Approximately 1–1.5 inches
- Temperament: Peaceful and social
Tank Requirements
Choose an established, fully cycled aquarium with generous floor space. A 15–20 gallon aquarium is a practical choice for a group and provides more room and water stability than a very small nano tank. Account for all tank mates when planning stocking.
- Substrate: Fine sand is ideal for foraging. Smooth, rounded gravel can work if kept very clean; avoid sharp substrate.
- Filtration: Provide effective biological filtration and good oxygenation, with gentle areas to rest. Protect filter intakes.
- Plants and cover: Use plants, driftwood, and hiding places while leaving open feeding areas.
- Lighting: Include shaded areas to help fish feel secure.
Water Parameters
- Temperature: 68–79°F (20–26°C)
- pH: 5.5–7.5
- Hardness: 2–10 dGH
- Ammonia and nitrite: 0 ppm
Prioritize stable conditions rather than making sudden adjustments to chase a number. Test regularly and use partial water changes matched for temperature and conditioned appropriately. Adjust maintenance to stocking and test results. Occasional trips to the surface for air are normal for corys; frequent gasping or sudden changes in behavior warrant checking water quality and oxygenation.
Feeding
Offer a varied diet of appropriately sized sinking pellets or wafers and small live or frozen foods such as baby brine shrimp and daphnia. Make sure food reaches the bottom and that each fish can feed without being outcompeted.
Feed small portions once or twice daily and remove uneaten food. These fish are not aquarium cleaners and cannot live on leftovers, algae, or fish waste.
Social Behavior and Group Size
Keep at least six of the same species, ideally ten or more when space and filtration allow. Other cory species do not replace a proper group of habrosus. Provide cover and observe feeding and behavior as the group settles in.
Tank Mates
Choose small, peaceful companions with overlapping water requirements, such as ember tetras or suitable small rasboras. Avoid aggressive fish, large predators, and fish that monopolize food. Shrimp may be suitable, but tiny shrimplets can be eaten.
Other Corydoras from Corydorables
These species are worth exploring for an appropriately sized community aquarium. Maintain a suitable same-species group for each and check adult size, temperature, and floor-space needs before combining them:
- Pygmy Corydoras Gastrodermus Pygmaeus — another small cory species.
- Tail Spot Pygmy Corydoras Hastatus — a small species with a distinctive tail marking.
- Albino Bronze Corydoras — a larger species for a more spacious setup, not a direct nano-tank substitute.
Breeding
Well-conditioned adults may lay adhesive eggs on aquarium surfaces or plants. Provide a varied diet and excellent water quality rather than using abrupt temperature changes to force spawning. A separate rearing setup can protect eggs and fry from predation. Prepare appropriately tiny fry foods and maintain gentle filtration and clean water.
Common Health Concerns
- Barbel damage: Check substrate cleanliness, sharp surfaces, and water quality.
- Red patches or sores: These signs can have several causes. Check water quality promptly and seek an aquatic veterinarian's help for diagnosis.
- White spots or suspected parasites: Confirm the problem and use a treatment labeled as appropriate for the fish, following the manufacturer's instructions or veterinary guidance. Do not automatically halve medication doses or raise the temperature beyond the species' comfortable range.
Quarantine new arrivals separately and monitor them before introducing them to an established community. Read our Quarantine Information guide for our recommended protocol.
