Hasbrosus Corydoras Care Guide - Aquarium Setup, Diet & Breeding

Hasbrosus Corydoras are among the smallest members of the Corydoras genus, with a compact body, rounded snout and distinctive dark markings. Their pale silver-grey base colour is crossed by a dark lateral stripe and complemented by darker patches around the dorsal fin and tail, giving them an attractive salt-and-pepper appearance.

These tiny bottom-dwelling catfish are peaceful, active and sociable. They spend much of their time exploring the substrate in short bursts, resting among plants and investigating the surroundings with their sensitive barbels. Unlike many larger Corydoras, they may also swim in the lower and middle areas of the aquarium.

In nature, Hasbrosus Corydoras live in shallow waterways where soft sediments, submerged vegetation and fallen leaves provide cover. Their underside is adapted for life close to the bottom, while their barbels help them locate food among the substrate.

This species is often sold as the salt-and-pepper pygmy cory or dwarf cory. Although diminutive, it has the characteristic peaceful group behaviour and charming foraging habits that make Corydoras popular in community aquariums.

Hasbrosus Corydoras originate from the upper Orinoco basin in northern South America, particularly the Llanos region of Venezuela and neighbouring areas of Colombia. They inhabit shallow, slow-moving streams and quiet margins with sandy or muddy bottoms, leaf litter and scattered vegetation.

A group of Hasbrosus Corydoras should have at least 40 litres, with a footprint of approximately 60 × 30 cm or larger. Prioritise floor space over height, using smooth fine sand or rounded, small-grained substrate that will not damage their barbels. Add dense planting, fine-leaved plants, leaf litter, driftwood and small sheltered areas, while leaving open patches for foraging. Gentle water movement, good oxygenation and clean, stable water suit their natural shallow-stream lifestyle.

Around 3.5 cm (1.4 inches) maximum adult length. Females are typically slightly larger and broader-bodied than males.

Hasbrosus Corydoras are omnivorous micro-predators and should be offered a varied diet of quality sinking micro-pellets, small catfish tablets, frozen bloodworm, daphnia, baby brine shrimp and other suitably sized foods. Occasional live foods encourage natural foraging and breeding behaviour. They do not live on algae or leftover food alone, so make sure food reaches the bottom and that every fish gets a share.

Hasbrosus Corydoras are suitable for peaceful nano-community aquariums. Good tankmates include small tetras, ember tetras, celestial pearl danios, chili rasboras, small pencilfish, otocinclus and other gentle dwarf species. They can also be kept with peaceful shrimp, although newly hatched shrimp may be eaten opportunistically. Avoid large cichlids, predatory fish, boisterous barbs, fin-nippers and other species likely to compete aggressively for food or view the corydoras as prey.

Hasbrosus Corydoras are egg scatterers that can be bred in a mature species or community aquarium. Condition a group with varied, protein-rich foods, then encourage spawning with a series of cooler, clean-water changes. Females usually carry a few adhesive eggs between their pelvic fins before placing them on plant leaves, glass or other smooth surfaces. Adults may eat the eggs, so remove the eggs or protect them in a separate breeding setup. The fry can be raised on infusoria or commercial fry food initially, progressing to freshly hatched brine shrimp as they grow.

Females are usually larger, deeper-bodied and noticeably broader when viewed from above. Males are smaller and slimmer, with a more streamlined profile; the difference is most apparent when the fish are mature or carrying eggs.
