Orange Laser Corydoras Care Guide - Aquarium Tips, Diet & Breeding

Orange Laser Corydoras are small, attractive armoured catfish named for the vivid orange-gold stripe that runs along the back and catches the light as they move. Their bodies are patterned in silver, bronze and dark markings, while their pale barbels and rounded fins give them the familiar, endearing appearance of a Corydoras.

These sociable bottom dwellers spend much of their time exploring the substrate with their sensitive barbels. They regularly pause to investigate objects, sift through fine material and make quick visits to the surface, a normal behaviour that allows them to gulp atmospheric air through a specialised section of the intestine.

In nature, they inhabit shallow Amazonian waterways, including calm margins, flooded forest channels and clear or tea-coloured tributaries. The habitat typically contains leaf litter, submerged roots and scattered vegetation, with soft sediments where the fish can search for small food organisms.

Orange Laser Corydoras are peaceful, active and highly engaging in a group. Like other Corydoras, they have rows of bony plates for protection and sharp fin spines that can cause painful punctures, so they should be handled carefully. Their exact scientific identity remains unresolved in the hobby, and the Orange Laser name is used for a recognised colour form within the aquarium trade.

Orange Laser Corydoras are a selectively identified aquarium trade form from the upper Amazon region of South America, associated with the Rio Nanay area of Peru. They are generally traded under a Corydoras sp. designation rather than a formally established species name.

A group of Orange Laser Corydoras should be kept in an aquarium of at least 60 litres, with a footprint around 60 x 30 cm or larger. Use smooth fine sand or another rounded, non-abrasive substrate so their barbels are not damaged, along with driftwood, smooth stones, leaf litter and hardy plants that provide cover while leaving open areas for foraging. Gentle to moderate filtration, good oxygenation and clean, stable water are important, with a secure lid recommended because Corydoras may occasionally leap.

Females can reach approximately 5 cm (2 inches) in adult length, while males are usually smaller at around 4–4.5 cm (1.6–1.8 inches).

Offer a varied diet of quality sinking catfish pellets and wafers supplemented with frozen or live foods such as bloodworm, brine shrimp, daphnia and blackworms. Their barbels are used to locate food, but they should not be expected to survive on leftover food alone; distribute sinking foods after the other fish have settled, and vary the diet to support condition and breeding.

Orange Laser Corydoras are peaceful community fish and can live with small tetras, rasboras, pencilfish, peaceful livebearers, small gouramis and other calm South American species. They also mix well with other gentle Corydoras when sufficient space and food are available. Avoid large or predatory fish, fin-nippers, boisterous bottom dwellers and aggressive cichlids, which may injure them or prevent them from feeding naturally.

Orange Laser Corydoras are egg-scattering catfish that can be encouraged to spawn with plentiful feeding and a series of partial water changes using slightly cooler, clean water. Males chase females, which collect fertilised eggs between their pelvic fins before placing them on aquarium glass, plants or other smooth surfaces. Remove the adults or protect the eggs from predation, and raise the hatchlings on infusoria or a suitably fine fry food before moving to larger foods.

Females are generally broader-bodied and slightly larger, particularly when viewed from above. Males tend to be slimmer and shorter, while mature females may show a noticeably fuller abdomen when carrying eggs.
