Water parameters
Overview
With black-edged pale saddles along its back and similar bands on the belly side, the zodiac loach has a pattern reminiscent of batik fabric. In juveniles the bands are joined and arrowhead-shaped; with age they break up. Adults reach 5–6 cm. In the wild it lives in large groups in the flowing streams of the Western Ghats.
Tank Setup
- At least 70 liters and 75 cm of length for a group of 4–6.
- 19–25°C, pH 6–7.5.
- Flowing, well-oxygenated water; a high-capacity filter, a circulation pump or an air stone.
- Stones, gravel and many shelters; it is sensitive to organic pollution, so a 30–50% water change every week.
Diet
An omnivore that feeds on small insects, worms and crustaceans. It accepts dry foods, but frozen or live foods should be given regularly.
Behavior and Compatibility
Hobbyists' experiences differ: some groups remain peaceful while some individuals defend their territory fiercely. It is more balanced with its own kind and enough shelters.
Good companions: danios, current-loving rasboras, small barbs, sturdy small fish.
Avoid: small and timid bottom dwellers, other small loaches that would share the same territory, warm-water species.
