Dwarf 'Pangasius' Care Guide - Aquarium Setup, Diet & Breeding

Dwarf 'Pangasius', Pseudeutropius brachypopterus, are small members of the Schilbeidae family rather than true Pangasius catfish. Their slender, silvery body is partly translucent, with a dark lateral marking that accentuates their streamlined profile and forked tail. Several pairs of barbels around the mouth reveal their catfish ancestry.

These active fish are sociable and spend much of their time moving through the middle and lower levels of the aquarium. They are easily startled when kept in small numbers, while a proper group displays more natural shoaling behaviour and greater confidence.

In the wild, they inhabit flowing freshwater environments where the water is well oxygenated and the fish can move through open channels and areas of marginal vegetation. Their sleek shape and active swimming style reflect life in currents rather than a sedentary bottom-dwelling existence.

Despite the trade name Dwarf 'Pangasius', they remain a relatively delicate community fish and should not be confused with the much larger iridescent shark catfish. Their modest adult size and attractive translucent appearance make them interesting subjects for a peaceful, suitably spacious aquarium.

Dwarf 'Pangasius' are native to freshwater habitats in the Indian subcontinent, particularly northern India and Bangladesh, in South Asia. They occur in rivers, streams and connected floodplain waters.

A group should be kept in an aquarium of at least 90 litres, with a footprint of roughly 90 x 35 cm or larger to provide useful swimming length. Use a soft sand or fine-gravel substrate, open swimming space and areas of hardy plants, driftwood or smooth rocks around the margins. Moderate water movement, efficient filtration and good oxygenation are beneficial, while subdued lighting and floating cover can help these sometimes skittish fish feel secure. Keep the aquarium securely covered because active fish may jump.

Up to about 8 cm (3.1 inches) in total length; females are usually slightly deeper-bodied and may be marginally larger than males.

Dwarf 'Pangasius' are opportunistic omnivores that accept quality small sinking pellets, granules and flakes, supplemented with frozen or live foods such as daphnia, mosquito larvae, cyclops and brine shrimp. Their narrow mouths suit small food items, and a varied diet helps maintain colour, condition and natural feeding behaviour. Offer modest portions that the group can consume promptly.

Dwarf 'Pangasius' suit peaceful community aquariums containing similarly sized, non-aggressive fish. Good companions can include larger peaceful rasboras, danios, small barbs, peaceful tetras, rainbowfish and other calm South or Southeast Asian community species. Avoid large predatory fish, aggressive cichlids, fin-nippers and boisterous tankmates that may outcompete or intimidate them. They should also not be housed with very slow, delicate fish that could be stressed by their active swimming.

Dwarf 'Pangasius' are egg-scattering fish, but reliable details of captive breeding are limited. A separate breeding aquarium with mature, conditioned adults, clean gently moving water and fine-leaved plants or spawning mops may encourage spawning. The adults should be removed after eggs are deposited, as they may eat them. The tiny fry require appropriately sized first foods, such as infusoria or commercially prepared fry food, followed by newly hatched brine shrimp as they grow.

Sexual differences are subtle. Mature females generally have a fuller, deeper body, particularly when carrying eggs, while males tend to remain slightly slimmer; reliable sexing is difficult outside breeding condition.
