Origin

Brochis britskii, commonly known as the Giant brochis, originates from slow-moving waters in South America, especially within the upper Amazon Basin in Brazil. These fish inhabit soft-bottomed rivers and floodplains with sandy or muddy substrates, often surrounded by aquatic vegetation and leaf litter.

Short description

Giant brochis are peaceful, bottom-dwelling catfish that belong to the Callichthyidae family. They resemble larger Corydoras species but are distinguished by their size and the number of rays in their dorsal fin. These sociable fish thrive in groups of 5 or more and are excellent choices for community aquariums with calm tankmates. Provide soft sand or fine gravel to protect their delicate barbels and ensure the tank has shaded areas and hiding spots made of driftwood or plants.

Feeding

These catfish are omnivores that will readily accept a variety of foods. Offer sinking pellets, quality flakes, algae wafers, and frozen or live foods such as bloodworms, blackworms, and brine shrimp. Feed them in the evening when they are most active near the bottom of the tank. Occasional feedings of crushed vegetables like blanched zucchini or spinach can also be beneficial.

Sexing

Females are generally larger and rounder than males, especially when viewed from above during the breeding season due to the presence of eggs.

Breeding

Breeding Brochis britskii is similar to other Corydoras-like catfish. Provide a larger tank with plenty of plants, caves, and hiding spots. Spawning may be encouraged by slightly cooler water changes and simulating rainy season conditions. Eggs are typically laid on plant leaves or the aquarium glass. Once eggs are laid, it's best to move them to a separate hatching tank to avoid predation. Fry hatch in about 4–5 days and should be fed infusoria or newly hatched brine shrimp.

Lifespan

The expected lifespan of Giant brochis is around 7–8 years, though with proper care, some individuals may live longer.

Tankmates and Setup

Due to their calm temperament, Giant brochis can be housed with other peaceful community fish such as rasboras, tetras, hatchetfish, or peaceful dwarf cichlids. Avoid aggressive or overly active species that may outcompete them during feeding. Maintain stable water parameters and perform regular water changes to keep the environment healthy. Gentle filtration and moderate lighting are recommended.
