赫氏似鳞头鳅

Overview

Widespread Lepidocephalichthys hasselti varies in pattern by locality, often showing a dark flank stripe or blotch row beneath a pale band. Even in rivers containing rapids, observed fish can favor quiet soft-bottomed bays, so strong aquarium flow is not automatically appropriate.

Distribution & habitat

Records extend from mainland Southeast Asia through Peninsular Malaysia, Sumatra, Java, and Borneo. Shallow muddy pools, backwaters, paddies, and river margins offer vegetation, roots, or leaves, with seasonal variation in water conditions.

Aquarium setup

Provide at least a 60 by 30 cm footprint with fine sand. Secure hardscape first, then add substrate and shaded refuges with leaves and wood. Coarse gravel can disrupt feeding or damage burrowing fish. Avoid strong flow while retaining oxygenation, protected intakes, and a close cover.

Diet & feeding

It extracts tiny invertebrates from substrate. Combine sinking prepared foods with regular small live or frozen meals rather than relying on scavenging.

Behaviour & compatibility

A group of four or more follows genus-level recommendations. Compatible quiet open-water fishes are potential companions; avoid territorial bottom-dwellers and account for possible predation on eggs or fry.

Sexual dimorphism

Males develop enlarged pectorals with fused inner rays forming a small upward-oriented flange. Females tend to be larger and fuller-bodied, with spotted flanks rather than the male stripe.

Notes

A partly scaleless crown does not imply a scaleless body. Tail reticulation, a small tail-base spot, and the pale flank stripe assist identification. Erectable subocular spines require care during netting.
