Royal Farlowella Catfish

The Royal Farlowella Catfish, scientifically known as Sturisoma panamense, belongs to the Catfish family group. Adults reach a maximum size of approximately 25 cm and have a depressed body shape with a moderate growth rate. Classified as peaceful, this species primarily occupies the mid-level and bottom zones of the aquarium and produces a high level of biological waste.

To thrive, the Royal Farlowella Catfish requires a freshwater only aquarium with a minimum volume of 150 litres and a tank length of at least 90 cm. Water temperature should be maintained between 24°C and 28°C, with a pH range of 6.5–7.5 and a general hardness of 4–15 dGH. A moderate water flow is preferred.

Due to its specialist needs, the Royal Farlowella 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.

When setting up an aquarium for the Royal Farlowella Catfish, a moderate water flow best suits their natural preferences. Because this species occupies the mid-level and bottom zones, the aquarium layout should prioritise open swimming space in the centre of the tank for free movement and sufficient floor space with hiding spots among rocks, wood, or dense planting. Useful additions include driftwood, which can serve as both a hiding place and a dietary supplement, an established tank with natural algae growth, as they depend on it as a primary food source, and dense planting to provide cover, break sightlines, and reduce stress.

Classified as peaceful, the Royal Farlowella Catfish is adaptable and can be kept singly or in a small group, offering flexibility when planning a community tank. When choosing tankmates, boisterous or fast-moving tankmates may cause this species undue stress. Selecting tankmates that favour different water layers from the mid-level and bottom zones can help reduce competition and territorial overlap.

Royal Farlowella Catfish is best for a fishkeeper who wants a species that can settle into a calmer community setup and can provide someone who understands its individual space requirements. It makes the most sense for a hobbyist who will actually build around its needs, especially driftwood.

The most common mistake is buying Royal Farlowella Catfish for looks first and only later discovering how its adult size, behavior, or bioload changes the whole tank plan. Another frequent problem is forcing it into an over-busy community when it would do better with more room or more deliberate tankmate choices.
