About
Zebra loaches are the quiet ones in a family known for boisterousness. They carry fine vertical stripes over an olive-gold body, they stay comfortably small, and they lack the pushiness that makes yoyos and clown loaches difficult in a mixed tank.
That makes them the botia to choose for a normal community. They still want a group, still want caves and still hunt snails, but they do it without dominating the tank.
They come from fast, shaded hill streams in southern India, and they're a good deal more retiring than their relatives. Expect to see less of them, particularly at first.
Tank setup
Keep your zebra loaches in a proper group. They're social, they sleep piled into the same cave, and a single one spends its life hidden.
Give them more hiding places than there are fish. Stacked stones, wood with hollows, and shaded corners all work, and the surplus is what stops the group squabbling over a single good spot.
Use sand or smooth fine gravel. They probe the substrate with their barbels continuously and anything sharp erodes them.
Keep the light low or heavily shaded. They're a shy fish and a dim tank brings them out far more than a bright one; floating plants do the job neatly.
Moderate flow and good oxygen suits the hill streams they came from.
Feeding
Zebra loaches eat readily once they've settled, taking sinking pellets, wafers, frozen and live foods.
They eat snails thoroughly. This is the usual reason people buy them, and they'll clear an infestation methodically over a few weeks — including any ornamental snail you were keeping deliberately.
Feed after the lights dim if the group is shy. They're more confident in low light and will come out for food they wouldn't chase in the middle of the day.
Avoid: assuming they'll scavenge enough from the community above them. They need food that reaches the bottom.
Filtration and flow
Filter well and keep the water moving. Their home streams are fast and clear, and they appreciate both flow and oxygen.
Keep nitrate down. Loach barbels erode in poor water long before any other symptom appears, so check them as a routine.
They're less tolerant than the hardier botias of a neglected tank, so regular changes matter here.
With plants
Zebra loaches don't eat plants and dig far less than the bigger botias, so a planted tank generally survives them intact.
Attach ferns, anubias and moss to wood anyway. It shades the tank, which suits a shy fish, and it's the safest planting around any loach.
Rooted plants in sand are usually fine, though newly planted stems may get nudged loose while the fish investigate.
Health
They catch ich readily. Both the choice of treatment and the amount belong to its instructions — products disagree about loaches, and those that do allow them often expect the ordinary quantity rather than a trimmed one.
Their skin is thin and their scales are tiny, which is exactly why they catch parasites so readily and why chemicals hit them hard.
Never net them. The spine under the eye catches in mesh — use a container, and watch your fingers.
Breeding
Deliberate breeding in home tanks is very rare, and commercial stock comes from hormone-induced spawning on farms.
The natural trigger is monsoonal: rising water, increased flow, cooler and softer conditions. Occasional accidental spawnings in home tanks follow large cool water changes, which fits that pattern.
Nothing about it is dependable. The adults would eat any eggs laid, so raising fry would mean moving them.
