Sumo Loach
Sumo Loach (Schistura balteata) has a robust, compact body — heavier and more muscular-looking than most Schistura species — with dark banding on a pale body. The 'Sumo' name reflects its stocky, powerful build. Sand loaches of the nemacheilid family are active, bold bottom-dwellers from the clear streams and rivers of Asia — territorial with their own kind but peaceful with other species, and more visible during the day than the nocturnal Kuhli group.
Feeding & Care Tip: Hikari Micro Pellets soaked briefly and Hikari Sinking Wafers make good daily staples. Supplement 2–3× per week with Hikari Frozen or Freeze-Dried Baby Brine Shrimp or Hikari Frozen or Freeze-Dried Bloodworms. Feed near the substrate and after the lights dim when most active.
Schistura and related sand loaches inhabit clear, often fast-flowing streams and rivers with sandy or rocky substrate. They are bottom-oriented and territorial — each fish establishes a small territory around a cave or rock and will defend it from conspecifics. Provide adequate caves and hiding spots to distribute territorial pressure.
Keep in groups of four or more — more loaches with more territory markers distributes aggression and produces more natural behavior. Compatible with mid-water and surface species that don't compete for bottom space. Avoid keeping with other bottom-dwelling territorial fish in small tanks.
Provide fine to medium sand substrate, multiple caves and shelters, and some water movement. These loaches are most interesting when kept in adequate groups with enough territory for each fish.
