Pepper Corydoras (Corydoras paleatus) Care Guide
Hardy peaceful catfish from temperate South America, recognised by its mottled greenish-brown pattern. One of the easiest Corydoras species for beginners and breeders.
Overview
Corydoras paleatus is a small, peaceful armored catfish in the family Callichthyidae native to southeastern South America. It is one of the hardiest and most widely kept Corydoras species, tolerating a wide range of water conditions and breeding readily in home aquaria.
Taxonomy
- Family: Callichthyidae
- Genus: Corydoras
- Scientific name: Corydoras paleatus
Habitat
The species inhabits the lower Parana River basin in Paraguay, Argentina and Brazil, plus coastal rivers in Brazil and Uruguay. It occupies slow-flowing streams, tributaries and standing waters with soft, silty substrates, and tolerates cooler subtropical temperatures than most tropical congeners.
Tank requirements
- Minimum tank volume: 60 L
- Temperature: 18-26 °C
- pH: 6.0-8.0
- GH: 2-20 °dGH
- School size: at least 6 individuals
- Lifespan: 5-8 years
- Adult size: 5-7 cm
Diet
Corydoras paleatus is an opportunistic omnivore. In the wild it consumes worms, crustaceans, insect larvae and plant matter sifted from the substrate. In aquaria it readily takes sinking pellets, granules and frozen foods such as bloodworm and Daphnia. Sustained temperatures above 30 °C are poorly tolerated.
Compatibility
This is a peaceful, gregarious species best kept in groups of six or more. It coexists well with small tetras, livebearers, rasboras and dwarf cichlids. A fine sand substrate is recommended to protect the barbels. Large or aggressive cichlids should be avoided.
Breeding
Breeding is straightforward and a common first project for hobbyists. A 2:1 male-to-female ratio works well; spawning is triggered by feeding live or frozen food and performing a large water change with cooler water. Females deposit 50-150 adhesive eggs in batches, which hatch in roughly four days at 24 °C. Fry require microscopic foods such as infusoria before progressing to microworms and Artemia nauplii.
Conservation status
IUCN Red List: Least Concern. The species is widespread, abundant in much of its range and supported by extensive commercial breeding.
