The Yellow Catfish is a large nocturnal species from India with striking golden coloration, peaceful temperament, and easy care in spacious tanks.
Overview
Horabagrus brachysoma, commonly known as the Yellow Catfish, Golden Catfish, or Sun Catfish, is a striking representative of the Bagridae family native to the freshwater habitats of southern India. In the wild, this species inhabits rivers and lakes in the states of Kerala and Karnataka, including the Vembanad lake system, where it favors areas with slow to moderate currents and abundant hiding spots.
Adults reach 30-40 cm in length, making Horabagrus brachysoma one of the larger catfish species available for the home aquarium. The fish has a memorable appearance: an elongated body cloaked in a rich golden-yellow coloration, with a distinctive dark eyespot at the base of the caudal fin. Long barbels help the fish navigate in darkness, which is unsurprising given that this is a predominantly nocturnal species. Life expectancy in captivity is 8-10 years with proper care.
Despite its impressive size, Horabagrus brachysoma has a remarkably peaceful temperament. During the day, the fish prefers to hide in shelters, becoming active and exploring the tank once dusk falls. This makes the Yellow Catfish a fascinating subject for evening observation.
Tank Requirements
Given the size of adult specimens, Horabagrus brachysoma requires an aquarium of at least 250 liters. Optimal water parameters are: temperature 22-28°C, pH 6.0-7.5, and general hardness (GH) 5-15. A powerful external canister filter is recommended to provide moderate flow and effective biological filtration.
The substrate should be soft — fine sand or rounded gravel — to protect the fish's sensitive barbels. The tank should be equipped with plenty of hiding places: driftwood, large rocks, ceramic tubes, and caves will create comfortable resting spots during the day. Subdued lighting or floating plants will help the fish feel more secure. Hardy live plants with strong root systems, such as Anubias and Echinodorus, are suitable choices, as a large catfish may accidentally uproot weakly anchored vegetation.
Feeding and Diet
Horabagrus brachysoma is an omnivorous species with a hearty appetite. In nature, the diet includes small fish, crustaceans, aquatic insects, and plant matter. In the aquarium, the Yellow Catfish readily accepts a wide variety of foods: high-quality sinking pellets and catfish tablets form the dietary staple, while live and frozen foods — bloodworms, brine shrimp, shrimp, and pieces of fish fillet — serve as excellent supplements.
Since Horabagrus brachysoma is nocturnal, feeding should be done in the evening or after the main lights have been turned off. Young fish should be fed daily, while adults do well on 4-5 feedings per week. It is important not to overfeed, as this species is prone to gluttony. Ensure that food is consumed within a few minutes and promptly remove any leftovers.
Care and Maintenance
The care difficulty for Horabagrus brachysoma is rated as moderate, making it suitable for aquarists with some experience. The key requirement is maintaining stable water parameters and performing regular tank maintenance.
Weekly water changes of 25-30% are necessary to remove accumulated nitrates. A large fish produces considerable waste, so robust filtration and regular substrate vacuuming are essential. Monitor ammonia and nitrite levels closely, especially during the first few months after setting up the aquarium.
The Yellow Catfish has a strong immune system and rarely falls ill when kept in proper conditions. However, these fish lack scales, which makes them more sensitive to copper-based and formalin-based medications. When treatment is necessary, dosages of such products should be halved. Note that catfish can sustain injuries from sharp decorations, so all tank furnishings should have smooth edges.
Compatibility
Thanks to its peaceful nature, Horabagrus brachysoma is well suited for species-only or community tanks with large, non-aggressive fish. Excellent tank mates include Clarias, large clown loaches, Pangasius, and peaceful medium to large cichlids.
It is important to remember that small fish under 5-6 cm may be perceived as prey, especially at night. Therefore, small tetras, rasboras, or neons should not be housed with the Yellow Catfish. Also avoid keeping it with aggressive or overly territorial species that may disturb the calm catfish during the day.
Keeping a group of 2-3 individuals is possible provided the tank volume is sufficient and separate hiding spots are available for each fish. Solitary keeping is also perfectly acceptable — the Yellow Catfish does not suffer from the absence of conspecifics.
Breeding
Breeding Horabagrus brachysoma in captivity is a considerable challenge, and successful aquarium spawnings are extremely rare. Sexual dimorphism is subtle: females tend to be slightly larger and develop a more rounded abdomen when ready to spawn.
To stimulate spawning, a temperature drop of 2-3°C followed by a gradual increase is recommended, simulating the monsoon season in the species' natural habitat. The water should be soft, with pH closer to the lower end of the range. Horabagrus brachysoma deposits eggs in shelters, after which the parents must be removed, as they are inclined to consume their own eggs.
Fry hatch within 2-3 days and initially feed on their yolk sac. Once the yolk sac is absorbed, the young should be fed newly hatched brine shrimp and microworms. Fry growth is relatively slow, and successful rearing requires stable water parameters and regular feeding with small portions several times a day.
