Standard (Adult)
The fully grown adult form. Very thick-bodied and heavily armored. While completely peaceful towards fish it cannot eat, it is an opportunistic nocturnal predator that will gladly consume sleeping Neon Tetras or similar small tank mates.
Differs in 1 trait from base species
Also known as: Adult Raphael Catfish
Juvenile (Grow-out)
Young specimens commonly sold in stores at around 4-6cm. They will establish hiding spots and emerge mostly at night to feed. Must be upgraded to a larger aquarium as they mature.

The Striped Raphael Catfish, scientifically known as Platydoras armatulus, belongs to the Catfish family group. Adults reach a maximum size of approximately 22 cm and have a depressed body shape with a slow growth rate. Classified as peaceful, this species primarily occupies the bottom zone of the aquarium and produces a high level of biological waste.
To thrive, the Striped Raphael Catfish requires a freshwater only aquarium with a minimum volume of 200 litres and a tank length of at least 120 cm. Water temperature should be maintained between 24°C and 30°C, with a pH range of 6–7.5 and a general hardness of 2–15 dGH. A moderate water flow is preferred. An aquarium test kit can help you monitor these values.
Due to its specialist needs, the Striped Raphael Catfish is best suited for fishkeepers who can provide a carefully planned setup. This species is available in 2 varieties: Standard (Adult) and Juvenile (Grow-out). Each may differ slightly in size, temperament, or care needs, so it is worth checking the specific requirements of the variety you plan to keep.
Striped Raphael Catfish Habitat Setup
When setting up an aquarium for the Striped Raphael Catfish, a moderate water flow best suits their natural preferences. Because this species occupies the bottom zone, the aquarium layout should prioritise sufficient floor space with hiding spots among rocks, wood, or dense planting. Useful additions include a sand substrate to accommodate their sifting behaviour and driftwood, which can serve as both a hiding place and a dietary supplement. Browse aquarium sand substrate options to find the best fit.
Striped Raphael Catfish Compatibility Notes
Classified as peaceful, the Striped Raphael Catfish is adaptable and can be kept singly or in a small group, offering flexibility when planning a community tank. When choosing tankmates, any fish small enough to fit in its mouth will likely be eaten, ornamental shrimp are not safe companions, and boisterous or fast-moving tankmates may cause this species undue stress. Selecting tankmates that favour different water layers from the bottom zone can help reduce competition and territorial overlap.

Striped Raphael Catfish Feeding & Diet Considerations
The Striped Raphael Catfish is a predatory species that will readily consume small fish, so nano or bite-sized tankmates should be avoided, will hunt and eat ornamental shrimp, making it unsuitable for shrimp-focused setups, will eat fry, so breeding efforts in the same tank are unlikely to succeed, and is primarily active at dusk and dawn, so offering food shortly after lights-off ensures it receives adequate nutrition.

Similar Species
Whiptail Catfish
Rineloricaria sp.
A highly cryptic, peaceful, and extremely slender catfish that mimics a twig or dead leaf. They are excellent scavengers and biofilm grazers that require smooth sand and driftwood to thrive. They are completely non-aggressive, lack the heavy armor of larger plecos, and do well in peaceful community setups.
Pictus Catfish
Pimelodus pictus
An extremely active, striking silver catfish with black spots and incredibly long barbels, native to South America. While peaceful toward similarly sized tank mates, they are highly effective nocturnal predators that will easily swallow small fish (like Neon Tetras) whole. They are scaleless and possess sharp pectoral spines that can easily become entangled in aquarium nets.
Bronze Corydoras
Corydoras aeneus
A highly popular, peaceful schooling catfish known for its armor-like scales (scutes) and active bottom-feeding behavior. They are essential clean-up crew members but require a dedicated sinking diet (not just leftovers). Sand substrate is strictly required to prevent erosion and infection of their sensitive barbels. They are 'gut breathers' and will occasionally dart to the surface to gulp atmospheric air.
Red-Tail Catfish
Phractocephalus hemioliopterus
A massive, fast-growing predatory catfish from the Amazon basin. Famous for its voracious appetite, bulldozer-like behavior, and distinct red caudal fin. Due to its enormous adult size (often exceeding 4 feet), it is strictly a 'monster fish' that requires a heated indoor pond or a colossal custom aquarium. It is highly predatory and will swallow absolutely any tank mate that can fit into its cavernous mouth.
Twig Catfish (Farlowella)
Farlowella acus
The Twig Catfish is an extremely elongated, master-of-camouflage suckermouth catfish from South America. True to its name, it mimics a dead twig perfectly, spending most of its time motionless on branches or plant leaves. It is a specialized aufwuchs and algae grazer that requires a mature tank, high oxygenation, and plenty of driftwood. They are completely peaceful but highly sensitive to fluctuating water parameters.
Featherfin Squeaker
Synodontis eupterus
A striking, large African catfish known for its spectacular, fan-like dorsal fin and its ability to produce a 'squeaking' sound when distressed or asserting dominance. While generally peaceful with similarly sized tank mates, it is highly territorial over its chosen cave and will predate on small fish at night.
