条尾墨头鱼

Overview

Dark bands near the margins of both tail lobes, together with an unmarked dorsal fin, help identify Garra fasciacauda. It is a river fish whose care should center on mature grazing surfaces and clean, well-oxygenated flowing water.

Distribution & habitat

The species occurs throughout parts of the Mekong system, including Tonle Sap. It uses swift reaches in both tributaries and larger channels. Seasonal movement includes dry-season migration from the Tonle Sap system toward the Khone Falls.

Aquarium setup

Arrange smooth stones and roots to provide browsing surfaces and shaded spaces. Strong circulation and oxygenation are essential, with turnover above ten tank volumes per hour suggested. Illuminate some surfaces for biofilm and establish the system before stocking. A secure lid prevents escape by climbing.

Diet & feeding

Use a mixed feeding plan: plant-rich sinking foods supplemented with small animal foods and occasional vegetables. Bloodworms, brine shrimp and chopped shrimp suit the animal component; softened greens add variety. Algae alone is insufficient.

Behaviour & compatibility

A well-chosen larger stream community is possible. Keep three or four or more only where space supports them, as individuals establish rank and lone fish can target similar species. Watch for concentrated pressure on subordinate fish rather than assuming all displays are harmless.

Notes

The relatively narrow side stripe should be considered together with the plain dorsal fin and paired tail bands. Tail color by itself is an incomplete identification clue.
