盖氏小波鱼

Overview

Microdevario gatesi is a miniature social fish infrequently encountered by aquarists. Clear dorsal and anal fins help distinguish it from related forms. Its gentle behavior suits a carefully arranged aquarium for similarly small fishes.

Distribution & habitat

It is known from Myanmar's lower Irrawaddy region and may be confined to the delta. This low alluvial landscape includes fields, marshes, oxbow waters, and channels shaped by seasonal flooding. The fish probably favors vegetated slow or standing freshwater rather than every habitat present in the wider delta.

Aquarium setup

Use dense planting and gentle filtration. Floating cover, branches, and wood can soften the light and provide quiet sheltered areas.

Diet & feeding

Tiny invertebrates, algae, and other plankton are considered likely foods in nature. Suitable fine dry preparations are accepted, but small live or frozen foods should make up much of the captive menu. Choose particles the fish can swallow easily.

Behaviour & compatibility

A dedicated group or similarly sized peaceful companions with matching needs are preferable. Eight to ten or more individuals encourage confidence and male display colors.

Sexual dimorphism

Females usually mature into larger, deeper-bodied fish than the more compact and intensely colored males.

Breeding

Successful aquarium reproduction of this species is uncertain, although related fish have been bred. An experimental approach can follow the genus-level pattern of scattering unguarded eggs among fine vegetation. Prepare a separate tank with aged water and abundant moss or mops; a small sponge filter is optional.

Introduce a conditioned pair or small mixed group, recognizing that additional adults increase egg predation. Remove them after two or three days. The comparative procedure suggests hatching near three days and swimming several days afterward, but these timings are not verified species-specific results. Begin with microscopic food before advancing to nauplii and microworms.
