Short-snouted Corydoras

Adults typically reach 5–6 cm in length. Their coloration is predominantly gray, with noticeable yellow hues. The catfish's body is dotted with black speckles, and its head and the base of its dorsal fin are adorned with dark vertical stripes. Outwardly, Corydoras brevirostris is almost identical to its closest relative, the Spotted Corydoras. The main difference lies in a more intense spotted pattern on the tail and a characteristic shortened snout, which gave this species its name.

The species was described from the Orinoco drainage in Venezuela; its range is only vaguely defined and is usually given as the Orinoco system plus unnamed coastal rivers in Suriname. It has not been recorded from the Amazon. In nature, it lives in slow-flowing rivers, tributaries, and streams with sandy or silty bottoms. Typical biotopes are characterized by fallen leaves, snags, and dense vegetation, which provide shelter. The water in its habitat is usually soft, with an acidic or neutral pH.

This is a peaceful, schooling fish that is active during the day. The catfish constantly explore the substrate in search of food, moving along the bottom of the aquarium. Due to their strong schooling instinct, it is recommended to keep a group of 6–8 individuals, which reduces stress levels in the fish and promotes natural behavior. They are well compatible with most non-aggressive fish species inhabiting the middle and upper water layers.

This hardy and unpretentious fish will not pose great difficulties even for a beginner aquarist. It is important to ensure and maintain a stable hydrochemical composition of the water, an optimal temperature regime, and timely feeding, while avoiding overfeeding. The key to biological balance will be preventing the accumulation of waste, such as food residues and excrement, which is achieved through the uninterrupted operation of equipment, primarily the filtration system, and regular aquarium maintenance. No specific care procedures are required for it. In terms of nutrition, Corydoras brevirostris is undemanding. It readily accepts a variety of popular aquarium foods, including dry, live, and frozen. It is advisable to use small sinking products so that the catfish can easily swallow them. Behavior and compatibility: The peaceful nature of the Short-snouted Corydoras and its ability to adapt to various conditions allow for a wide range of tank mates. Excellent choices would be equally calm and non-aggressive fish of comparable size. It is recommended to purchase these catfish in groups of 4–6 individuals.

An omnivorous species, in nature it feeds on small invertebrates, insect larvae, and organic detritus. In the aquarium, they accept specialized dry foods in the form of sinking tablets or granules, as well as frozen foods such as Artemia, Daphnia, or bloodworms. For maintaining health, a varied diet including both animal and plant components is recommended.

Breeding is similar to other members of the genus. Spawning is paired or communal, stimulated by frequent water changes with cooler water and an increased proportion of protein food in the diet. Eggs are laid on the substrate: broad plant leaves, decorations, or aquarium glass. Parents may eat the eggs, so it is recommended to remove the adults after spawning is complete. Fry hatch after 3–5 days and begin to feed independently.

Fish are sensitive to water quality and substrate condition. When kept on sharp or coarse gravel, their delicate barbels are often damaged, opening the way for bacterial infections. It is important to keep the substrate clean, siphon it regularly, and avoid the accumulation of organic waste. With proper water parameters and feeding, they have good immunity.

When choosing, pay attention to the fish's activity: healthy individuals are constantly moving and actively exploring the bottom. The body should be clean, without ulcers, film, or fin damage. An important sign of health is intact, undamaged barbels around the mouth. Avoid purchasing fish that appear emaciated, apathetic, or show signs of rapid breathing.
