Dwarf Chain Loach

The Dwarf Chain Loach (Ambastaia sidthimunki) is an active, small, social loach recognized by the dark chain-like markings along its body. Unlike kuhli loaches, it is often out exploring during the day and needs a lively group and plenty of hiding places.

Dwarf Chain Loach Care

• Adult size: Approximately 2–2.5 inches
• Tank: 30 gallons or larger recommended for a proper group, prioritizing floor space
• Group: At least 6, preferably 8–10 or more with sufficient space
• Temperature: 75–82°F
• pH: Approximately 6.0–7.5
• Flow: Moderate circulation and good oxygenation
• Substrate: Smooth sand or fine rounded gravel with caves, roots and plant cover
• Diet: Omnivorous; small sinking pellets, frozen or live foods and quality wafers
• Temperament: Active and social; may be boisterous with timid fish

Tank Mates and Feeding

Choose active, peaceful fish of similar size that can tolerate the loaches' busy behavior. Avoid very timid bottom dwellers or delicate long-finned fish. They may eat small pest snails, but should not be purchased only for snail control. Feed a complete sinking diet.
