Snakeskin Barb Care Guide - Aquarium Setup, Diet & Breeding

The Snakeskin Barb is a small, elegant cyprinid with a warm copper to golden-brown body marked by a distinctive chain of dark, diamond-shaped or rhomboid blotches. The pattern gives the species its common name, while translucent fins and subtle reddish tones add to its appeal when the fish are settled and displaying naturally.

This species is active without being relentlessly boisterous. A group spends much of its time moving through the middle and lower levels of the aquarium, frequently forming loose shoals and then separating to investigate its surroundings. Males may intensify their colour and display alongside one another, especially when courting.

In the wild, Snakeskin Barbs inhabit quiet forest waters where fallen leaves, submerged roots and branches break up the habitat. The heavy canopy limits direct sunlight, and decomposing vegetation releases tannins that create the clear, tea-coloured water associated with Southeast Asian blackwater environments.

Desmopuntius rhomboocellatus was formerly placed in the genus Puntius and is sometimes sold under the name Rhombo Barb. It is a peaceful, relatively uncommon community fish that is especially attractive in a properly sized group, where its pattern and natural social behaviour can be observed at their best.

The Snakeskin Barb is native to the peat swamps, slow-flowing streams and blackwater habitats of Indonesian Borneo, particularly in Kalimantan. These habitats are typically shaded by dense rainforest, with tannin-stained, soft and acidic water.

A group should have at least a 75-litre aquarium, with a footprint around 90 x 30 cm or larger; a longer tank is preferable because these active shoaling fish use horizontal swimming space. Use a soft sand or fine-gravel substrate, add driftwood, roots, dried leaves and dense planting, and leave open areas for swimming. Floating plants and subdued lighting help recreate the shaded forest conditions in which the species evolved. Gentle filtration, good oxygenation and stable, clean water are important, while botanicals can provide cover and naturally tint the water.

Up to 8 cm (3.1 in) in total length. Females are usually slightly larger and deeper-bodied than males.

Snakeskin Barbs are omnivores that benefit from a varied diet. Offer a quality small granule or flake as a staple, supplemented with frozen or live foods such as daphnia, mosquito larvae, brine shrimp and bloodworm. Small portions of vegetable matter, including spirulina-based foods, help provide balance. Feed modest amounts that the group can consume promptly, preferably in more than one small feeding each day.

Snakeskin Barbs are peaceful community fish and can be kept with similarly sized rasboras, peaceful small barbs, danios, tetras, peaceful loaches and small Corydoras. Other gentle fish from soft-water Southeast Asian or South American communities can also be suitable when their temperature and water chemistry needs overlap. Avoid large, predatory or highly aggressive species, fin-nippers and boisterous tankmates that may intimidate them or outcompete them for food.

Snakeskin Barbs are egg-scattering fish that can be bred in a separate, mature breeding aquarium with soft, acidic water, gentle filtration and fine-leaved plants or spawning mops. Condition a group with plenty of live or frozen foods, then introduce the adults when females are full of eggs. Spawning usually takes place among the vegetation, but the adults may eat the eggs, so remove them after spawning or protect the eggs with a spawning grid. The eggs generally hatch within a day or two, and the tiny fry can be raised on infusoria or another suitably small first food before progressing to newly hatched brine shrimp.

Males are generally slimmer and develop stronger copper, orange or reddish colouration, particularly during courtship. Females tend to be fuller through the abdomen and are often a little larger, with less intense breeding colour.
