Spotted raphael catfish (Agamyxis pectinifrons ) – bottom, interestingly colored aquarium fish from the Kirysowatych family.


South America. Range of occurrence in nature not very clear, probably limited to the Amazon basin in Bolivia, Colombia and Peru. Found in a variety of environments, but most often in slow-flowing or stagnant waters, with lots of vegetation and sunken roots. During the rainy season, they migrate to flooded forest areas.

Characteristics and disposition

They can be up to 15 cm in length. The body is cylindrical, sagittal, with a flat lower abdomen. Large head with small eyes. The muzzle is broad, with three pairs of whiskers, one pair on the upper jaw, two on the lower jaw. As in related species, it is armored with bone plates along the body line.

The first ray of the dorsal fin is hard and sharp. Dark brown or bluish black in color, with an irregular pattern of small bright points. Fins dark, with spots and stripes that may run together or intersect. Light underbelly with a similar pattern. Coloration becomes more and more uniform with age.

The species can easily be confused with the identical looking Agamyxis albomaculatus. Without knowing the origin, these fish are indistinguishable. A. albomaculatuscomes from the runoff of the Rio Orinoco River in Venezuela. Interestingly, they are called talking catfish.

Even in the aquarium, they make screeching sounds (by rubbing their pectoral fins). They lead a nocturnal lifestyle, in heavily lit aquariums they may not be visible to the aquarist’s eyes. Females are more massive and rounder. They live up to 15-20 years in good conditions.

Nutrition and feeding

It is omnivorous and will accept most commonly available dry and frozen foods in the aquarium.

A balanced diet is recommended . Every day, you can give good-quality dry food that sinks to the bottom, regularly supplemented with live or frozen, e.g. bloodworm, tubifex, mosquito larvae. Occasionally, chopped earthworms can be given.


The combs will feel best in a spacious reservoir, with a soft, sandy ground, not too brightly lit, with a lot of hiding places and shaded places.

For decoration, you can use, for example, dry roots, artificial ceramic caves. They are not aggressive , but adults can eat smaller fish that fit into their mouths. They will be a good complement to the aquarium of the Amazon biotope with, for example, mild tetras, cichlids and other catfish. They are gregarious fish, kept in large numbers (4 or more) will exhibit more natural behavior. They also group with related species Platydoras armatulus, Acanthodoras spinosissimus , and Amblydoras hancockii .


There was no reproduction under aquarium conditions . For commercial purposes, they are bred on livestock farms using hormones
