Royal Farlowella

The Royal Farlowella is a medium-sized catfish known for its elongated body and long, extended snout. Its golden-tinted coloring, the source of its species name, gives it a striking appearance as it clings quietly to driftwood or the tank floor. Native to Colombia's Magdalena River system, this gentle, algae-eating fish rarely bothers tankmates and tends to be shy, often seeking cover in hiding spots. Because it's best suited to intermediate keepers and is sensitive to sudden water quality changes and low oxygen levels, consistent, careful water changes and stable water parameters are essential to keeping it healthy over the long term.

Royal Farlowella key facts

Care level
Intermediate
Lifespan
8-10 years
Size
18-20cm
Temperature
25〜29℃
Diet
Algae, vegetable matter such as spirulina and greens, and sinking wafers
Tank
It reaches 20cm standard length and needs width to match its elongated body. Add driftwood branches, vertical twigs and slender plant stems for it to rest against, and keep the water well aerated.
Water Temperature & Quality
FishBase gives 25-29C, pH 6.0-8.0 and 5-19dH. It reacts badly to sudden changes, so make small, frequent water changes.
Tank Mates
It is a quiet, plant-grazing bottom fish, so choose tankmates that will not outcompete it at feeding time.
Diet & Feeding
Largely herbivorous. Besides algae, offer spirulina tablets, blanched spinach and cucumber. A diet dominated by meaty foods does not suit it.
Breeding & Spawning
Captive breeding has rarely been recorded, so aim first for stable long-term keeping in a tank with driftwood and vertical twigs, using small, frequent water changes.
Health & Notes
The IUCN assesses it as Data Deficient and it is not listed by CITES. It is also sold under the old name Sturisoma aureum, so watch for inconsistent scientific names when buying.

About Royal Farlowella

Royal Farlowella is a medium-sized catfish with golden coloring and a long snout. This gentle, algae-eating species is sensitive to sudden water changes and low oxygen, making it best suited to intermediate keepers.

7 things to know before welcoming a Royal Farlowella

  1. 1A Tank With Hiding Spots

    Royal Farlowella is a shy fish that prefers to stay tucked away in cover. Driftwood and rockwork arrangements help it feel secure and settled.

  7. 7Plan for Adult Size

    Adults grow to about 18-20 cm. Make sure your tank has enough length and driftwood to comfortably accommodate its elongated body.
