安氏鳞头鳅

Overview

Two dark chevrons on the tail are a useful feature of Lepidocephalichthys annandalei. Some traded fish differ from the original description in tail shape, however, so identification should not rest on a sales label alone.

Distribution & habitat

It occurs in the middle and lower Ganges–Brahmaputra region of Nepal, Bangladesh, and northeastern India. Shallow slow streams, swamps, oxbows, backwaters, and paddies have soft sediment and plentiful vegetation or woody debris. Water depth and clarity vary seasonally.

Aquarium setup

Provide at least a 45 by 30 cm footprint with soft sand for burial. Coarse gravel can injure fish or inhibit feeding. Secure hardscape before adding substrate, and create shaded refuges with wood and leaves. Avoid strong flow while maintaining oxygen, protect filter intakes, and keep the aquarium covered.

Diet & feeding

It sifts substrate for tiny invertebrates such as insect larvae and crustaceans. Sinking prepared foods can accompany regular small live or frozen supplements.

Behaviour & compatibility

Genus-level guidance favors four or more conspecifics. Choose peaceful fishes from compatible conditions, especially open-water companions. Other sand loaches need checking for territoriality, and eggs or fry may still be eaten.

Sexual dimorphism

Males develop enlarged pectorals with thickened fused inner rays. Females are generally a little larger and fuller-bodied.

Notes

The notch described in the tail may be absent in traded examples, so compare markings and provenance. Erectable subocular spines can entangle netting.
