African leaffish

Polycentropsis abbreviata

Short deep leaf-shaped body, large mouth and shifting mottled colour

This compressed predator extends its large mouth to capture prey. Mottled, pale and very dark states occur; contrasting juveniles are the same species.

Adult length: Up to 8 cm (standard length, without the tail fin)
Water temperature: 26–31 °C
Lifespan: 5–8 years
pH: 6–6.5
Hardness: 1–10 dGH

Natural habitat: Occurs in waters of African rainforest regions.

Quiet hovering does not make it safe with small fish or shrimp; confirm water stability and reliable feeding before purchase.

Appearance and identification

Unlike Monocirrhus polyacanthus, it lacks the conspicuous lower-lip stalk and has a shorter outline. It resembles South American Polycentrus.

Social behaviour and territory

Males build leaf-associated bubble nests and tend eggs; breeding does not guarantee peaceful groups.

Compatibility limits

Small fish and shrimp are prey.

Space requirements

Provide mature soft acidic water, gentle flow and shaded broad-leaf cover. A 60 × 38 cm footprint is reported. Keep at 26–31°C.

Aquarium environment

Broad leaves and floating plants offer cover and nesting surfaces. They cannot protect prey; keep feeding and leftovers observable.

Diet and feeding

Offer suitable live invertebrates. Live fish are not obligatory, but acceptance of dead foods varies. Check each fish feeds.
