Spotted Raphael Catfish Care Guide - Tank Setup, Diet & Breeding

The Spotted Raphael Catfish is a striking, heavily armoured catfish with a dark brown to nearly black body covered in pale cream spots and broken markings. Its bold pattern helps it disappear among shadowed roots, leaves and woody debris, while the broad head and rows of protective plates give it the rugged appearance typical of doradid catfish. The pectoral and dorsal spines can lock into place, so this fish should be handled with particular care.

Spotted Raphael Catfish are native to tropical South America, particularly parts of the Amazon and Orinoco drainage regions, including Brazil, Colombia, Peru and Bolivia. They inhabit slow-moving tributaries, flooded forest margins and other sheltered freshwater environments.

A single Spotted Raphael Catfish should have an aquarium of at least 200 litres, with a footprint around 120 by 45 cm; a larger tank is preferable for adults or groups. Use smooth sand or fine rounded gravel so its sensitive barbels are not damaged, and provide caves, hollow wood, rockwork and dense areas of cover. Dim lighting, shaded retreats, gentle to moderate flow and open swimming space around the decor create a natural, secure environment. A tightly fitting lid is advisable because catfish can escape through gaps.

Up to about 15 cm (6 in) in standard length. Females are often slightly larger and fuller-bodied than males, although individual size varies.

These omnivorous bottom feeders accept sinking carnivore pellets, catfish tablets and wafers, supplemented with foods such as bloodworm, brine shrimp, chopped earthworms, mussel and other meaty frozen or live offerings. They may also take softened vegetables and fallen foods, but their diet should be centred on varied, protein-rich sinking foods. Feed after the aquarium lights dim, when they are naturally most active, and remove uneaten food promptly.

Spotted Raphael Catfish are peaceful community fish and can live with similarly peaceful South American species such as larger tetras, peaceful barbs, angelfish, gouramis, peaceful cichlids and other suitably sized catfish. They generally ignore tankmates and spend much of the day concealed. Avoid very small fish that could fit in their mouths, aggressive species that may harass them, and tankmates likely to compete aggressively for caves or food.

Spotted Raphael Catfish are rarely bred in ordinary home aquariums. In nature they are cave-spawning fish, and a compatible pair may use a sheltered tube or cave to deposit eggs. Commercial breeding generally relies on specialist facilities and hormonal induction, so home keepers should regard successful spawning as unusual rather than an expected project. Any fry would require very small, nutritious foods and excellent water quality.

Females are usually broader and more robust through the abdomen, particularly when mature, while males tend to be slimmer. The differences are subtle, and sexing young Spotted Raphael Catfish reliably can be difficult.
