Care and water
Behavior
Peaceful and sociable; keep in a group of 8 or more. Hides in plants when kept alone.
- sand
Food
Sinking micro-pellets, wafers, frozen bloodworms and daphnia, fed after lights-out.
Tap a food to see what it is.
Male or female
Females grow larger and, when mature, are noticeably rounder and broader-bodied than males, especially when full of eggs; easiest to see from above.
Health

Breeding
Egg-scatterer (sticky eggs) · Moderate
Can be bred like most corys: two or more males per female and a large soft, cool water change. Eggs go on glass, fine plants (often the underside of leaves near the bottom) or spawning mops. Fry are not the easiest to raise.
Keep a group with more males than females; condition with live and frozen foods. Males chase females in a 'T-position' before spawning.
40 L tank with a sponge filter, fine sand and java moss or spawning mops; a cool water change is often what sets them off.
A large cool (3-5 C) water change, lower barometric pressure feel, and heavy feeding of live foods.
Sticky eggs placed on glass, fine plants or mops; they hatch in 3-4 days and breeders add methylene blue or alder cones to stop fungus.
Move eggs to a hatching tub with an air stone and a pinch of methylene blue or alder cone. Feed microworms and newly hatched brine shrimp; keep water spotless.
- Dirty sand that causes barbel erosion
- Not removing eggs from hungry adults
- Skipping the cool water change trigger
Where it lives in the wild
The story of the salt-and-pepper cory
A tiny cory (about 3.5 cm) from the Llanos of Venezuela and Colombia, with a salt-and-pepper pattern and 2-3 dark blotches along the side. Despite its size Seriously Fish says it needs at least a 60 cm tank and is unsuitable for nano aquaria.
Stanley Weitzman, a specialist in small South American fishes, described this cory in 1960 from Venezuela. It is one of the dwarf cories, reaching only about 3.5 cm. Its fine salt-and-pepper speckling gave it its common name, and it has become a favourite for small planted tanks.
First described by Stanley H. Weitzman in 1960.
- It is one of the smallest Corydoras, at about 3.5 cm.
- Unlike some dwarf cories, it stays mostly on the bottom.
- It is best kept in a group, as it is a sociable shoaling fish.

Moved from Corydoras to the resurrected genus Hoplisoma, and the ending changed from habrosus to habrosum to agree with the neuter genus name. Dias et al. (2024, Zool. J. Linn. Soc.) split Corydoras into five genera. Described as Corydoras habrosus Weitzman, 1960; keep that as an other name.

Agrees with legacy. 'Males often more colourful' is not stated by the sources.
Seriously Fish: Hoplisoma habrosum - Breeding
No source says it is especially easy to spawn; 'easy' is unverified.
Seriously Fish: Hoplisoma habrosum · FishBase: Hoplisoma habrosum summary - Eggs and young
Hatch time 3-4 days agrees with legacy 3-5. No source gives an egg count, so 'dozens' is unverified.
Seriously Fish: Hoplisoma habrosum - Storycorrected
Corrections: range includes Colombia; the 'good fit for nano tanks' claim is contradicted by Seriously Fish; 'dark bar through the tail' is not in the sources (the marks are 2-3 blotches on the flank). Often mixed up with H. cochui and with the 'pygmy corys' Gastrodermus pygmaeus and G. hastatus, which are all sold as 'dwarf/pygmy cory'.
