🔍 Why Consider This Loach?

• Small Footprint, Big Presence
  Topping out around 2 inches, Blue Tail Borneo Loaches are compact, but their striking sky-blue tail and rippling body pattern stand out against smooth stones, wood, or glass. They're in near-constant motion—gliding across surfaces with their suction-cup bellies like little hovercrafts.

• Peaceful and Community-Friendly
  These loaches are peaceful and non-aggressive, making them excellent tankmates for other calm fish like rasboras, small tetras, or shrimp. They won’t pick fights and prefer to mind their own business along the bottom.

• Active Algae Grazers
  While not a substitute for a full cleanup crew, they do spend their time grazing surfaces and can help keep biofilm and soft algae in check. It’s fascinating to watch them work—more like watching a miniature stingray than a typical fish.

🧬 Character and Behavior: What Makes This Loach Special?

The Blue Tail Borneo Loach is all about movement, texture, and natural curiosity. It adds a calming, mesmerizing flow to the tank, especially when placed in a layout that mimics its natural riverbed home.

• Non-Aggressive & Inquisitive
  It’s peaceful to the core—never nipping, chasing, or posturing. It spends its day gliding across rocks, leaves, or driftwood with deliberate, gentle motion.

• Mildly Social but Not Schooling
  While not a tight schooler, this species thrives in groups of 3–5. They’ll loosely associate and explore together, often settling into the same area when resting or grazing.

• Constant Grazer
  These loaches are always on the move, lightly scraping biofilm and microalgae from surfaces. Unlike some loaches, they’re gentle on plants and won’t dig or disturb the aquascape.

• Responsive to Water Flow
  They love a tank with current. Place them near a powerhead or filter outlet and they’ll park themselves like little river stones, flexing their undersides to stay perfectly still.

• Shrimp and Nano Fish Compatible
  They’re a dream companion for dwarf shrimp and small peaceful fish. Their calm demeanor and grazing habits won’t interfere with even the tiniest tankmates.

🪨 Aquascaping Tips

• Use rounded river stones, driftwood, and a sand or fine-gravel substrate.

• Avoid sharp decorations—these fish constantly graze and need smooth surfaces.

• Add floating plants or low-light species to soften lighting and create comfort zones.
