The Sumo Loach (Schistura balteata) is a small, active freshwater fish from the loach family, known for its bold coloration and semi-aggressive temperament. Here’s a breakdown of what you need to know:
Scientific Name:
Schistura balteata
Common Names:
• Sumo Loach
• Belted Loach
Origin & Habitat:
• Found in fast-flowing streams and rivers in Southeast Asia, particularly in Thailand, Myanmar, and surrounding regions.
• Prefers clear, oxygen-rich waters with rocky substrates.
Appearance:
• Typically grows up to 3-4 inches (7-10 cm).
• Has a stocky body with distinctive dark vertical bands across a lighter, often yellowish or brownish body.
• Resembles a “sumo wrestler†in build, which is how it gets its name.
Behavior & Temperament:
• Semi-aggressive and territorial, especially with its own kind or similarly shaped bottom dwellers.
• Can be kept in small groups (3-5) to reduce aggression, but each will establish a territory.
• Very active and loves darting between rocks and decorations.
• Can be a fin-nipper, so avoid keeping it with slow-moving, long-finned fish.
Tank Requirements:
• Minimum Tank Size: 20-30 gallons for a small group.
• Substrate: Sand or smooth gravel with plenty of rocks, caves, and hiding spots.
• Filtration: Strong, high-flow filtration (replicating river conditions).
• Temperature: 72-79°F (22-26°C).
• pH: 6.0-7.5.
• Oxygenation: High, as they come from fast-flowing waters.
Diet:
• Omnivorous but leans toward carnivorous.
• Accepts sinking pellets, bloodworms, brine shrimp, daphnia, and small invertebrates.
• Will also scavenge on algae and detritus but needs a high-protein diet.
Compatibility:
• Best with fast-moving fish that can handle its temperament, like danios, barbs, and other small loaches.
• Avoid slow-moving, long-finned, or overly peaceful fish.
• Shouldn’t be kept with shrimp or small invertebrates—it will see them as food.
Breeding:
• Very rare in home aquariums.
• Likely requires seasonal changes in water parameters to trigger spawning.
• Not much documentation on successful captive
