🐡 Dwarf Chain Loach Ambastaia sidthimunki

The Dwarf Chain Loach (Ambastaia sidthimunki) is a moderate-care, peaceful species from Thailand. Adults reach roughly 2.5", so plan on a minimum tank of 20 gallons. Keep the water between 75–82°F with a pH of 6.5–7.5. This is a schooling fish — keep a group of at least 5 so it feels secure and colors up. As an omnivore, it does best on a varied diet appropriate to its feeding style.
