Clouded Archerfish Care Guide - Aquarium Setup, Diet & Breeding

The Clouded Archerfish is a distinctive surface-dwelling predator with a laterally compressed, silvery body marked by dark blotches along the back and sides. Its upturned mouth and prominent eyes are adapted for watching prey above the water, while the body shape allows it to turn quickly beneath the surface. Compared with some better-known archerfish, Toxotes blythii is generally a less boldly patterned species, with a subdued, cloudy appearance that gives it its common name.

Like other archerfish, it is famous for shooting a forceful jet of water at insects resting on overhanging vegetation. The fish calculates the position of its target from below the surface and knocks the prey into the water, where it can be swallowed. Young fish may learn this behaviour by observing other archerfish, and the species can become highly engaging to watch when it is settled and feeding confidently.

Clouded Archerfish are social but can be competitive, particularly around food and preferred surface positions. They usually spend much of their time near the top of the aquarium, although they will move through the middle levels when exploring or pursuing prey. A group can establish a hierarchy, so cramped conditions and too few hiding places may lead to persistent chasing.

In the wild, this species occurs around calm margins, forested banks, submerged roots and overhanging branches. It is often associated with clear to lightly stained water and habitats where terrestrial insects regularly fall onto the surface. Its natural history is less thoroughly studied than that of the commonly exported banded archerfish, and specimens are comparatively uncommon in the aquarium trade.

Clouded Archerfish are native to freshwater and tidal-influenced habitats in Myanmar, in mainland Southeast Asia. They are associated with the waters of the Ayeyarwady and Salween regions, although the precise limits of their distribution are not fully documented.

A group should be given at least 250 litres, with a footprint of about 120 × 45 cm; a larger aquarium is preferable for adult fish or a bigger group. The tank should provide a generous open surface area, strong filtration and excellent oxygenation, together with a completely secure lid because archerfish are powerful jumpers and may shoot water beyond the aquarium. Leave an air gap above the water so the fish can aim at prey and maintain clear access to the surface. Use smooth sand or fine rounded gravel, driftwood, rocks and hardy plants arranged around open swimming space, with branches or emergent vegetation offering cover without obstructing the surface.

Up to about 15 cm (6 in) in adult length; females may become slightly larger and deeper-bodied than males.

This carnivorous predator naturally feeds mainly on insects and other small animals at or above the water surface, along with aquatic invertebrates and occasional small fish or crustaceans. Offer a varied diet of crickets, flies, appropriately sized grasshoppers, mealworms, prawns and other meaty foods, supplemented with good-quality floating carnivore pellets. Live or moving prey can provide useful enrichment, but avoid relying on feeder fish and remove uneaten food promptly.

Clouded Archerfish can be housed with robust, peaceful fish that occupy the middle or lower levels, such as large peaceful barbs, silver dollars, larger rasboras and suitable catfish or loaches. Tankmates must be too large to be swallowed and should tolerate active feeding and a warm, well-oxygenated aquarium. Avoid tiny fish, delicate species, slow surface feeders and fin-nippers, as they may be harassed or treated as prey. Keeping several archerfish together can spread aggression, but overcrowding should be avoided.

Clouded Archerfish are not commonly bred in home aquaria, and reliable captive-breeding reports are scarce. In nature, archerfish are believed to reproduce seasonally and may move toward brackish or coastal waters to spawn. Providing a large, mature aquarium with excellent water quality, varied live foods and compatible adults may encourage courtship, but successful spawning and raising fry require specialist facilities and marine or brackish rearing conditions that are not well documented for this species.

Sexes are difficult to distinguish reliably by external appearance. Mature females are often somewhat fuller in the body and may grow slightly larger, while males tend to remain slimmer, but these differences are not definitive.
