短攀鲈 · Sparkling Gourami

Overview

Trichopsis pumila is a small labyrinth fish with a solid dark side stripe and a row of blotches above it. Both sexes produce audible sounds, adding an acoustic dimension to courtship and disputes.

Distribution & habitat

It occurs in the lower Mekong basin of Laos, Vietnam, Cambodia, and Thailand, and in central and southern Thai drainages. Habitats include swamp forest, floodplains, canals, rice fields, and ditches, with a preference for very slow or still water and dense vegetation.

Aquarium setup

Provide a shaded, well-planted aquarium with surface cover, wood, and small retreats. Dried leaves add shelter and support microorganisms that can supplement fry food. Keep filtration gentle and avoid strong circulation.

Cover the tank securely while leaving space above the water. The fish jumps well and needs access to warm, humid air. This air layer is especially important for normal labyrinth-organ development in fry.

Diet & feeding

Wild food probably includes insects and other small invertebrates. Settled aquarium fish generally learn to accept dry foods, but plentiful suitably small live or frozen items remain useful, including Daphnia, brine shrimp, and bloodworms.

Behaviour & compatibility

Keep a pair or small group, alone or with similarly small, very peaceful fishes. Larger or forceful companions may intimidate it and monopolize food. Reports of predation on small freshwater shrimp mean shrimp companionship cannot be assumed safe.

Sexual dimorphism

Sexing can be difficult. Mature males typically have stronger colors and longer extensions to several fins. Visible ovaries in mature females can provide an additional clue.

Breeding

The male builds a bubble nest in a tube, beneath a broad leaf, or among fine surface vegetation. He often excludes the female until it is ready. During spawning embraces, small packets of eggs are released and collected by him, with the sequence repeated until laying ends.

Adults can usually remain afterward. The female stops participating while the male guards and tends the nest. Eggs hatch in about one or two days, then remain for another two or three days while the yolk is absorbed. He retrieves fallen young. Once they swim freely, his interest fades, and adults do not normally consume the brood.

Start fry on infusoria-sized foods, progressing to microworms and brine shrimp nauplii. Use small, regular water changes and retain the warm, humid air layer.

Notes

Specialized pectoral structures generate the croaking sounds used during social interactions. Acoustic and visual signals may help fish assess rivals, but should not be treated as a guarantee against conflict.
