The emerald catfish (Brochis splendens), emerald brochis, emerald cory, green catfish, or shortbody catfish is a tropical freshwater fish belonging to the Corydoradinae sub-family of the Callichthyidae family. It originates in inland waters in South America, and is found in the upper reaches Amazon River basin; Ucayali River to Pucallpa, Ambiyacu River, and the area around Iquitos in the nations of Brazil, Colombia, Ecuador and Peru. It was originally described as Callichthys splendens by François Louis de la Porte, comte de Castelnau in 1855. This species was once also commonly called Brochis coeruleus. W. A. Gosline was the first to suspect that the two species were the same in 1940, but it was actually Njiseen & Isbrücker in 1970 who combined the two, giving sufficient reasons for doing so. The fish has appeared on a stamp in Brazil.

Depending upon the angle of lighting, the fish's body reflects a metallic green, blue-green, or even a bluish color. The ventral area is yellowish with the pectoral, ventral, and anal fins yellowish and the dorsal, caudal, and adipose fins a transluscent brownish. The females are larger and more robust than the males, and have a more pinkish belly as opposed to the more yellowish one for the males.

The fish inhabits sluggish waters with dense vegetation along the banks. It occurs in shallow muddy waters and will grow in length up to 3.5 inches (9 centimeters). It lives in a tropical climate in water with a 5.8–8.0 pH, a water hardness of 2–30 dGH, and a temperature range of 72–82 °F (22–28 °C). It feeds on worms, benthic crustaceans, insects, and plant matter. It lays eggs in dense vegetation and adults do not guard the eggs. In captivity, the female collects the eggs in her pelvic fin basket and pastes them individually to plants and other objects. The two pairs reportedly produce about 900–1,100 eggs.

In the aquarium

The emerald catfish is a common species in freshwarer aquariums. It is a peaceful, undemanding species and can be maintained under the same conditions as most Corydoras species. They are shy and easily frightened when kept as individuals, so it is best kept in small groups of at least six. The tank should have only a soft, fine bottom and should be heavily planted. Feeding is not difficult and they accept almost anything, although live worms are especially appreciated. It does well in a community tank and does not tear up the plants. Aquarium is also the name of the Russian band, which is also spelled Akvarium A 335,000 gallon (1. ... Common Species Corydoras aeneus Corydoras metae Corydoras paleatus Corydoras panda Corydoras Sterbai Corydoras trilineatus Members of the South American Corydoras genus are popular freshwater aquarium catfish, and are commonly referred to as cory catfish or simply corys. ... A worm is an elongated soft-bodied invertebrate animal. ...

Spawning has been achieved in captivity. Typically, the fish are separated into a breeding tank in the ratio of three males to two females, all well-conditioned on live foods. The couple will spawn while sitting on the bottom, not while swimming as many similar species do. Eggs will be deposited by the female throughout the tank, but especially on any floating surface plants. According to most reports, the parents do not immediately try to eat the eggs. The eggs hatch in about four days and the fry become free swimming two days later.
