Tiger Hillstream Loach Tank Setup
Give them at least 95 litres (25 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. Always keep a group of at least 3 of their own kind - kept alone or in pairs they tend to turn shy, nippy, or wash out in colour.
What Do Tiger 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.
Tiger Hillstream Loach Tank Mates
The Tiger Hillstream Loach is peaceful, which is the first thing to weigh up when you choose tank mates. It's a shoaling fish, so settle a group of 3 or more of its own kind before adding anything else - a stressed, lonely fish is far more likely to nip or hide. 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 Tiger 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.
