Corydoras concolor

Corydoras concolor
Concolor Corycat
Corydoras concolor was described by Stanley Weitzman in 1961. It is one of the dwarf armoured catfish from South America that have become increasingly popular over the last few years. Small and peaceful it makes an ideal fish for a community tank or an excellent breeding challenge for an advanced hobbyist. C. concolor is found in the Orinoco river system in Venezuela and Colombia. It is available only occasionally in shops either as a wild caught import or as a product of some hobbyist’s breeding effort. It’s not that expensive being just slightly dearer than the common bronze and pepper corydoras. Males – a small catfish with typical corydoras profile of arched back and flat underside. Males will reach about 5.5cm only. Colour is slate blue (from which it derives the common name – slate cory) with an emerald-green sheen over the operculum (gill covers). Specimens in good condition develop a rusty orange wash over the rear half of their body and also on their unpaired fins. A dark eye mask can just about be made out in some lighting conditions. Males have a high dorsal fins which in mature animals can reach an impressive length. This is a stunning fish which in no way deserves the name given to it – concolor means “of one colour”.

Females – up to 6cm and similar to the male but fuller bodied. Does not develop the exaggerated dorsal finnage of the males. Easy to keep in most water conditions, just avoid extremes of pH and temperature. Suitable for a planted community tank of peaceful fish. Like most Corydoras species they are less shy and show more natural behaviour when kept as a group. Six or more is ideal.
