Croaking gourami

Trichopsis vittata

Usually three dark lines run along the flank, often with a dark spot above the pectoral fin.

Mature males have long rear anal-fin rays; colour and stripe intensity vary among populations and states.

Adult length: Up to 7 cm (standard length, without the tail fin)
Water temperature: 22–28 °C
pH: 5–7.5
Hardness: 1–15 dGH

Natural habitat: Inhabits lowland swamp forest, floodplains, tributaries, canals and rice fields, favouring vegetated still or slow water.

Keep at 22–28°C, pH 5.0–7.5 and 1–15 dGH. Provide shaded planting and floating cover, with gentle water movement.

Appearance and identification

Males tend to be larger with longer pelvic, dorsal, anal and caudal rays; both sexes vocalise.

Social behaviour and territory

Pairs and groups need different amounts of space. Nesting males drive other fish away.

Compatibility limits

Usually peaceful outside breeding, it can drive other fish away from the nest. Groups need more space, cover and escape routes than a single pair.

Space requirements

Allow a 60 × 30 × 30 cm aquarium for a pair, with more space for a group.

Aquarium environment

Keep a secure lid and an air space above the water: this fish can jump and uses its labyrinth organ to breathe air. Leave routes to the surface between floating plants.

Diet and feeding

Offer recognised dry foods alongside small frozen or live foods for variety.
