Snakeskin Barb

The Snakeskin Barb, scientifically known as Desmopuntius rhomboocellatus, is a striking and active freshwater fish native to the blackwater peat swamps of Borneo. Known for its unique scale pattern resembling snakeskin, this species is a visually appealing addition to well-maintained community aquariums.

Physically, Desmopuntius rhomboocellatus has a laterally compressed, elongated body with a golden to reddish-brown base color. Its most distinctive feature is the irregular dark markings along its body, forming a pattern reminiscent of snakeskin. The fins are typically translucent with subtle orange or red hues. Adults grow to about 2 to 2.5 inches (5 to 6.5 centimeters) in length, making them a great mid-sized schooling fish.

In the aquarium, Snakeskin Barbs thrive in well-planted tanks with ample swimming space. A tank of at least 20 gallons is recommended for a small school, with larger tanks preferred for bigger groups. A soft, sandy substrate with plenty of driftwood, leaf litter, and shaded areas helps mimic their natural habitat. Dim lighting and the addition of tannins from botanicals further enhance their coloration and comfort.

Water parameters for Desmopuntius rhomboocellatus should reflect their blackwater origins. They prefer soft, acidic water with a pH range of 4.5 to 6.5 and temperatures between 74 to 82°F (23 to 28°C). Low mineral content and clean, well-filtered water are essential for maintaining their health. Regular water changes help keep water conditions stable.

Feeding Snakeskin Barbs is straightforward, as they are omnivorous and readily accept a variety of foods. A balanced diet of high-quality flakes or micro pellets, supplemented with live or frozen foods such as daphnia, brine shrimp, bloodworms, and mosquito larvae, helps maintain their health and vibrant coloration. Occasional vegetable-based foods like spirulina flakes or blanched zucchini are beneficial.

Snakeskin Barbs are peaceful, social fish that should be kept in groups of at least six to encourage natural schooling behavior and reduce stress. They are excellent tank mates for small tetras, rasboras, gouramis, corydoras, and other non-aggressive species. They should not be housed with overly aggressive or fin-nipping fish.

Breeding Desmopuntius rhomboocellatus in captivity is possible with careful conditioning. They are egg scatterers, and spawning occurs among fine-leaved plants or over a spawning mop. Males display more intense coloration during courtship. After spawning, the eggs hatch in 24 to 36 hours, and the fry become free-swimming shortly after. The fry should be fed infusoria or finely crushed fry food before transitioning to baby brine shrimp.

Overall, Desmopuntius rhomboocellatus is a unique and visually striking species that adds color and activity to blackwater and community aquariums. Their schooling nature, peaceful temperament, and beautiful patterning make them an excellent choice for aquarists looking to maintain a well-balanced and naturalistic setup.
