Lacerda's Cory Care Guide - Aquarium Setup, Diet & Breeding

Lacerda's Cory is a compact, armoured bottom-dwelling catfish with a broad head, short barbels and a dark, subtly patterned body. Its base colour ranges from grey-brown to olive, often with darker markings across the back and flanks that help it blend into sand, leaf litter and shaded streambeds.

Like other members of the callichthyid family, it has rows of bony plates rather than conventional scales. The pectoral and dorsal spines can lock into place, giving the fish useful protection from predators and making it important to handle this species carefully.

These catfish spend much of their time investigating the substrate with their barbels, searching for small invertebrates and other edible material. They are generally peaceful, but mature males can become noticeably territorial, especially when competing for access to females or favoured resting places.

In the aquarium, Lacerda's Cory is most active during the day and around dusk, particularly when kept with others of its kind. It is a less commonly encountered relative of the familiar Corydoras species and is valued for its natural appearance, interesting behaviour and distinctive adult males.

Lacerda's Cory is endemic to southeastern Brazil in South America. It is associated with Atlantic Forest waterways, particularly clear, shallow streams and tributaries in the coastal region of Espírito Santo and neighbouring areas.

A group should have at least a 80-litre aquarium, with a footprint of approximately 90 by 30 cm or larger to provide useful bottom area. Use soft sand or very smooth fine gravel so the barbels are not damaged, together with shaded areas formed by driftwood, rounded stones, leaf litter and hardy plants. Provide open feeding space as well as caves or woodwork that create separate territories, and maintain good oxygenation with gentle-to-moderate water movement. Secure filtration and regular maintenance are especially important because this species forages directly across the substrate.

Males can reach about 8 cm (3.1 inches), while females are usually slightly shorter at around 6–7 cm (2.4–2.8 inches).

Offer a varied sinking diet of quality catfish pellets, wafers and granules supplemented with frozen or live bloodworm, daphnia, brine shrimp and other small aquatic foods. Occasional blanched vegetables can add variety, although this species is primarily a small invertebrate and detritus feeder rather than an algae specialist. Feed after other fish have settled so that food reaches the bottom, and do not rely on leftover food to sustain it.

Lacerda's Cory is suitable for peaceful community aquariums with small tetras, rasboras, pencilfish, peaceful danios, small livebearers and other calm South American species. It can also be kept with peaceful dwarf cichlids and non-aggressive bottom dwellers, provided there is enough floor space. Avoid large predatory fish, fin-nippers, boisterous feeders and aggressive cichlids, as well as other territorial bottom fish that may compete for shelter. Several males may display and spar without serious harm, but cramped conditions should be avoided.

Lacerda's Cory can be bred in a mature, well-conditioned aquarium. Keep a small group with several males and females, feed them generously with meaty foods, and trigger spawning with a partial water change using slightly cooler, clean water. The female carries a few adhesive eggs between her pelvic fins before placing them on glass, plants or other smooth surfaces. Remove the adults or protect the eggs from predation, and raise the fry on powdered foods and newly hatched brine shrimp once they become free-swimming.

Males are generally larger and more heavily built, with a broader, more elongated snout and stronger bristles or odontodes on the cheeks and sides of the head. Females are typically shorter-bodied, fuller through the abdomen and less ornamented around the head.
