Salt and pepper cory / dwarf cory
Corydoras habrosus
Also known as: salt and pepper cory, dwarf cory (habrosus. Not pygmaeus), Salt and pepper cory, Dwarf cory (Habrosus. Not Pygmaeus)
Fishori provides conservative planning guidance, not guarantees.
Based on multiple reputable aquarium care sources with strong agreement. Use the numbers here as planning defaults — your room, water, and routine still shape real-world outcomes.
The smallest cory at 3.5 cm with a black-and-white spot pattern. Needs a large school on fine sand and a quiet nano setup.
Best for
Planted nano tanks 60L or more with fine sand substrate and a school of ten in a low-activity community.
Avoid if
Active boisterous community fish, sharp substrate, or tanks under 40L.
Top things that go wrong
- Group welfare — not a solo display fish. Plan at least **8** together for normal behaviour; smaller groups often mean stress, colour loss, or nipping depending on species.
- Shrimp & snails. Shrimp: compatible in most setups. Cherry shrimp and other dwarf species coexist with peaceful small fish, though baby shrimp are food for almost any fish that gets to them.
Common mistakeSalt-and-pepper cories with active danios or large fish at feeding time. They get outcompeted for food and lose condition slowly.
What most shops don't tell you
- 1.Confused with Corydoras pygmaeus in shops. Habrosus stays on the floor; pygmaeus shoals in midwater.
- 2.Housed with large cichlids in small tanks. A 3.5 cm cory is bite-sized for many cichlid mouths.
- 3.Sinks food quickly; target-feed if outcompeted by fast midwater fish. Avoid deep bare glass where barbels abrade on sharp grit.
About this species
Salt and pepper corys are 3.5 cm bottom-sifters with a short snout and pepper-speckled body. Needs fine sand, warm stable water, and a group of eight or more of their own kind. Not the same fish as the pygmy cory (Pygmaeus), which shoals in midwater. Check the label, not the bag colour, in the shop.

Common setup sketches
Conservative patterns from Fishori fields — still run the pair checker for every species you add; sketches are not a stocking guarantee.
Rough 90L+ layout: one calm centrepiece, 8–12 small tetras/rasboras, 6–8 corydoras-type bottom fish — verify every name in the pair checker before buying.
Safe directions on file include: Chili Rasbora, Ember Tetra, Pygmy Corydoras.
Prioritise 8+ of Salt and pepper cory / dwarf cory in 60L+ with filtration sized for messy feeding — add only mates that already pass pair checks with this species.
Tank mate intelligence
Use the "Often compatible" lists as a shortlist, not a stocking plan. Always run the pair tool and check the footprint of your actual tank first. Verify behaviour for Salt and pepper cory / dwarf cory against your own reading before you buy.

Behaviour, temperament, and what to watch
Prose and lists come from the same record: read temperament first, then glass-level signals so you are not surprised after day three.
Salt and pepper cory / dwarf cory is peaceful in mixed company.
Stress / aggression triggers on file
- Sudden crowding
- Poor water quality
Fin nipping: Not a habitual fin-nipper, but individuals can still test fins under stress or in a crowded tank.
Predation: Not a predator toward similarly-sized community fish. The usual community caveats about mouth size still apply for very small fry or shrimp.
Territory: Not strongly territorial, but still claims a working area in the tank. Give it room to settle without overlapping the next species' patch.
Planted tanks: excellent — easy plant ideas
In the glass: typical and warning signs
- Often calm on the glass — bursts of movement around food or tank disturbance.
- Shoaling/schooling: most colour and confidence show when the group meets **8+**.
- Clamped fins, gasping at the surface, hiding non-stop, or refusing food after the first week.
- Rapid breathing when parameters swing — fix ammonia/nitrite first, then reassess mates.
- Low listed risk — still watch new introductions.
- Separate or rehome if injuries appear, one fish is pinned, or feeding becomes a daily chase.
- If water is stable but behaviour worsens, reduce stocking or remove the highest-impact species first.
Fish behaviour can vary between individuals and tank setups. Always observe new fish closely after introduction.
Care parameters: water, food, inverts, grouping
Chemistry and group rules sit here so you are not re-reading the same line from tank mate or temperament blocks. Swim level is in the plan grid above.
Hardness
soft
Diet
omnivore
Mixed diet: a quality flake or pellet as the staple, with frozen or live foods two or three times a week.
Shrimp & snails
Shrimp: compatible in most setups. Cherry shrimp and other dwarf species coexist with peaceful small fish, though baby shrimp are food for almost any fish that gets to them.
Shoaling species. Buy 8 or more of one species together. Smaller schools sulk, lose colour, and redirect their schooling energy at whatever else is in the tank.
Egg scatterers and schoolers still spawn in stable tanks. Have a plan for the fry, or accept that the parents and tank mates will eat them in a community setup.
- Hold 22 to 26 °C steadily on a real thermometer, not the dial on the heater.
- Aim for pH 6 to 7.2 and a hardness you can re-test in two weeks. A one-time strip in the shop car park is not a water test.
- Schooling species. Buy 8 or more from the same tank on the same day before adding any centrepiece fish.
- Tank volume meets or exceeds 60L published minimum for adults.
- You can stock at least 8 individuals (group welfare).
- Heater can hold 22–26°C without cooking cooler-water tank mates.
Explore and stocking hubs
Same library as the rest of Fishori: tank-mate index for this species, category peers, guides, and litre-based stocking lists where min tank on file is within the hub volume.
Plan with tools
Pair-level rules and multi-fish stocking use the same conservative engine — add this fish in the tank builder only after mates pass pair checks.
Filtration & heating
A 60L minimum tank needs a filter rated for at least 240L/hr turnover and a heater to hold 22–26°C reliably.
Plant suggestions
Salt and pepper cory / dwarf cory does well in planted tanks. Plants compatible with 22–26°C and pH 6–7.2:

How Fishori evaluates compatibility (same logic as pair and tank tools).
- Seriously Fish. Corydoras habrosus
Primary: aquarium size, water chemistry, behaviour, and compatibility (URL verified in upgrade script; recheck if site content changes).
- FishBase. Corydoras habrosus
Secondary: taxonomy, distribution, and maximum length in nature; cross-check with aquarium import lines and measured tank parameters.
- Wikipedia. Corydoras habrosus
Secondary: general species context; verify all husbandry numbers against a dedicated aquarium care sheet and your test kit, not a single table row.
Evidence notes
- The Seriously Fish profile for the binomial in this record was successfully reached as the primary aquarium reference.
- FishBase contributes natural-range size and habitat context. Translate those numbers through your heater, your water report, and your tank footprint before stocking.
- Wikipedia is only cited if the article URL returned OK. Use it for orientation, not as the only care sheet for an import.
- All compatibility text reflects typical hobby experience and the Fishori model. Individual fish, shop stress, and the order tank mates are added in can still defy a single-paragraph label.
- Fishori profiles work from typical aquarium trade sizes and hobby care norms. Specialist site checks and literature review for this species are not yet recorded here, so the ranges on this page are planning numbers rather than guarantees.
