Overview
Striped Raphael Catfish (Platydoras armatulus) is a bottom-dwelling fish for aquariums where the layout leaves enough open substrate area and the water stays stable.
Use these values as planning checks, then make sure the aquarium still has room for behavior, group needs, and calm community fish.
Care requirements
With a Beginner – Intermediate care level, Striped Raphael Catfish is approachable, but it still needs stable water, clean substrate, and a well-planned stocking group.
Because it uses the bottom area, leave enough open substrate area instead of crowding that part of the aquarium.
Plan the aquarium around the group, not just one individual.
With a lifespan of up to 20 years, this is a fish to plan for long term rather than an impulse addition.
Aquarium size and space needs
An aquarium of 300 L or larger can be a reasonable starting point, but it should not be read as permission to overstock.
At up to 25 cm, Striped Raphael Catfish stays small, but a group still needs room to move, feed, and avoid constant competition.
Uses the bottom area, so leave enough open substrate area for movement and feeding.
A group of 6 or more should have enough open substrate area for movement and feeding.
Water parameters
The temperature range for this fish is 22 to 30 °C, which fits many tropical freshwater aquariums. Choose other fish with overlapping temperature needs.
The pH range for this fish is 6 to 7.5. That points to slightly acidic to neutral water, but stability is more important than sudden corrections.
The GH range for this fish is 2 to 20 dGH. That gives some flexibility, but sudden changes are usually more stressful than a stable value that is slightly imperfect.
Temperament and compatibility
As a peaceful bottom-dwelling fish, Striped Raphael Catfish is best kept with calm species that will not harass it or dominate the feeding area.
If kept in a group of 6 or more, the aquarium should have enough open substrate area for the group rather than being planned around a single fish.
Because this fish uses the bottom area, compatibility is easier when other fish are not all competing for the same swimming space.
Swimming zone and behavior
This fish uses the bottom area, so leave enough open substrate area for movement and feeding.
Because this species is best planned as a group of 6 or more, bottom space matters more than body size alone.
Feeding
As an omnivore, Striped Raphael Catfish should receive a varied diet rather than one repeated food type.
Because it feeds near the bottom, make sure food reaches the substrate and is not completely taken by faster fish in the open water.
Natural habitat and origin
This profile currently lists the origin as Brazil Argentina Paraguay Venezuela. Treat this as a broad regional note rather than a complete habitat description.
Before adding this fish
