Borneo Hillstream Loach Tank Setup
Give them at least 75 litres (20 US gallons) and a tight-fitting lid, since many loaches are escape artists. Keep the water at 68-75°F with a pH around 6-7.8; soft sand suits the ones that like to burrow.
What Do Borneo Hillstream Loaches Eat?
They're not fussy eaters - feed a varied diet, rotating good-quality dry, frozen, and gel foods rather than the same thing every day, and match the food size to their mouths.
Borneo Hillstream Loach Tank Mates
The Borneo Hillstream Loach is peaceful, which is the first thing to weigh up when you choose tank mates. Good matches come down to the whole stocking list working together - temperature, tank size, and temperament - not any single label. Before you buy, run your full stocking list through our stocking calculator. It weighs temperament, adult size, and water needs together, which a single species page can't do on its own.
Are Borneo Hillstream Loaches Good for Beginners?
Doable once you test water regularly and catch problems before fish look sick. If this is your first tank, pick something more forgiving and come back later.
