About Dwarf Chain Loach
The dwarf chain loach is a small, beautifully patterned fish from the clear, flowing streams of Thailand. Its body features a distinctive chain-like pattern of dark markings on a golden background, with some individuals showing more interconnected blotches and others displaying separate spots. At just 2 inches, they are one of the smallest botia-type loaches and are perfectly sized for smaller community tanks. Dwarf chain loaches are diurnal and far more active during daylight than most loach species, making them more visible and entertaining to observe. They are social, curious fish that interact frequently with each other and constantly explore their environment.

Expert Tips
Keep dwarf chain loaches in groups of at least six in a tank of 20 gallons or more. They are one of the most daytime-active loach species, so they provide more visible entertainment than nocturnal species. Provide a sandy substrate with smooth rocks, caves, and driftwood. They prefer moderate current and clean water at 72-82°F. Feed sinking micro-pellets, crushed wafers, and frozen foods like baby brine shrimp and daphnia. They are excellent pest snail controllers even in small tanks. Dwarf chain loaches are generally peaceful but maintain a clear social hierarchy within their group with mild chasing. They are sensitive to water quality and need consistent maintenance.
