Striped Raphael Catfish

Adults of this species can reach up to 20 cm in length. In appearance, it is almost indistinguishable from the common Raphael Catfish, but upon closer inspection, some morphological differences can be noted: its head is more pointed, its eyes are slightly smaller, and its adipose fin is longer. The coloration and characteristic body pattern are similar in both catfishes. Dark brown or black hues predominate, complemented by a white stripe running from head to tail. The edges of the fins also have a light border. The Orinoco Raphael Catfish is reliably protected from potential predators by its tough skin, which feels like sandpaper, and sharp spines—these are modified first rays of the fins.

The species is endemic to South America and inhabits exclusively the Orinoco River basin in Venezuela. In nature, it occupies the bottom areas of water bodies, preferring places with subdued lighting and natural shelters.

This fish is distinguished by its peaceful and calm disposition, showing a tendency to stay in groups of its own kind. It coexists well with other non-aggressive catfish species and other aquarium inhabitants. However, it should be noted that due to its omnivorous nature, this catfish can pose a threat to very small neighbors or fry, so their cohabitation is not recommended.

For a group of 2–3 such catfishes, an aquarium of at least 250 liters will be optimal. In terms of decor, special attention should be paid to the lower stratum, as the Orinoco Raphael Catfish spends a significant part of its life there. It is recommended to create both open areas and appropriately sized shelters, for example, from large snags. The catfish is safe for aquarium plants. Nevertheless, it is preferable to use hardy species with well-developed root systems, or those that can grow on the surfaces of snags or stones. In terms of care, it is relatively undemanding and adapts well to various conditions. Aquarium maintenance includes standard procedures: weekly partial water changes with fresh water, removal of organic waste, and regular equipment checks.

This species is omnivorous, actively eating everything it finds on the bottom of the water body. The basis of the daily diet can consist of popular dry sinking foods, which can be supplemented with live or frozen bloodworms, small earthworms, as well as pieces of shrimp or mussels. Unlike many catfishes, this species actively searches for food not only in the evening or at night but also during the day.

Breeding has not been described. Thorny catfishes spawn in aquaria only very rarely, and for this species there are no confirmed cases. No external differences between males and females are reported, and all fish in the trade are wild-caught.

Like other members of the thorny catfish family, this species possesses robust health and high resistance to diseases when kept under proper conditions. The main danger comes from mechanical damage to the skin when using unsuitable nets or sharp decorations, which can lead to the development of secondary bacterial infections. Prevention involves maintaining water cleanliness and regular partial water changes.

When purchasing, attention should be paid to the integrity of the skin, the absence of white spots, ulcers, or damage on the body. A healthy fish should show activity in searching for food, even during the day, despite its nocturnal lifestyle. It is important to note that due to the presence of sharp spines on its fins, the fish should be transported with caution, avoiding the use of mesh nets in which it can get entangled.
