Brochis splendens
A deep-bodied relative of the corydoras whose flanks shine metallic emerald green. A higher dorsal-fin ray count separates it from Corydoras proper. It is hardy and easy to keep long term.
Brochis splendens is a callichthyid bottom dweller found widely through the Amazon basin. Seriously Fish gives a standard length of 8cm and FishBase 9.9cm, making it large for a corydoras-type fish in the trade. The body is deep and thick, and the flanks shine metallic emerald to blue-green depending on the angle of light. A high dorsal-fin ray count is the morphological hallmark of Brochis; after Britto merged the genus into Corydoras in 2003, FishBase again treats Brochis splendens as the valid name. It tolerates 20-28C, pH 5.0-8.0 and 2-15dGH. Its size demands floor area, and a 120 x 45cm base of about 243 litres is the minimum. Peaceful and strongly gregarious, it is best kept in groups of six to eight or more. Like other callichthyids it rises to the surface to gulp air for intestinal respiration. IUCN status is Least Concern.

A 120 x 45cm base of about 243 litres is the minimum. It is large and active, so prioritise floor area over volume.
20-28C, pH 5.0-8.0 and 2-15dGH. Tolerance is broad but it suffers in low oxygen and high nitrate.
Peaceful and gregarious; keep six to eight or more. It suits community tanks of similarly sized peaceful fish.
A foraging omnivore. Base the diet on sinking dried food with frozen bloodworm and Tubifex; its size means larger rations.
Eggs are laid close to the water surface and are easy to move elsewhere for rearing.
It surfaces regularly to gulp air for intestinal respiration, so never block its route to the surface. IUCN status is Least Concern.
Beginner. This is a beginner-friendly species. No special equipment or experience is required, and it can be kept successfully with basic care setup.
The ideal temperature for Emerald Catfish is 20〜28℃. Avoid sudden temperature changes and maintain a stable environment.
The average lifespan of Emerald Catfish is 5-7 years. With proper care and nutrition, they can live a long and healthy life.
Emerald Catfish typically reaches 8-10cm as an adult. Size may vary depending on care conditions and individual genetics.
Emerald Catfish feeds on: Sinking dried foods, frozen bloodworm, Tubifex. Aim for a balanced diet with appropriate feeding frequency.
