Place the Food on Rock, Because the Current Steals Broadcasts
Hillstream loaches live in fast, oxygen-rich flow and feed by grazing the algae film on stones, so loose food scattered into the water column is simply blown away before these bottom-hugging fish reach it. Scatter-feeding for hillstreams means placement, not sprinkling: press pieces of algae wafer or softened gel food onto flat rocks where the loaches already graze. Put a piece on the big central stone, one on a lower rock near the glass, and one on a sheltered stone behind the wood, so the food waits on the grazing surface itself. The loaches then shuffle from rock to rock, rasping each station clean, which is their stream-bed foraging pattern slowed down for a tank.
One Rock Per Loach Keeps the Scatter Peaceful
Hillstream loaches are mild fish, but a single food rock still draws pushing and shadowing, with the largest fish owning the piece while smaller ones cling nearby and wait. Spreading portions across as many rocks as you have loaches gives each fish a station it can graze without contest, and the group visibly fans out across the rockwork instead of stacking on one stone. Vary which rocks carry food from feed to feed, so the loaches keep exploring the whole scape and graze algae evenly rather than wearing one stone smooth. Vegetable slices weighted against the rocks with a clip or a pebble make good extra stations that last longer than wafer pieces. Even a single loach patrols more of the tank when its food is not always waiting in the same corner, so lone fish deserve the full spread too.
Prepared Food Tops Up Grazing, It Does Not Replace It
A hillstream tank's real food is the film growing on its rocks, so scattered prepared food should be a supplement sized to what the grazing cannot provide. In a mature tank with strong light and visible algae growth, small stations a few times a week may be plenty; in a newer, cleaner tank the loaches need food placed more often because there is little to graze between feeds. Judge by the rocks: stones kept polished bare by hungry loaches mean the scatter should grow, while untouched wafer pieces mean the film is feeding them and portions can shrink. Keep uneaten pieces from rotting in the flow by removing what remains after several hours.
Watch Bellies From the Glass Side
Hillstream loaches feed against the glass often enough that you can audit the scatter from outside the tank: a well-fed loach shows a gently rounded belly pressed to the glass, while a hollow, concave underside means that fish is losing the competition or the stations are too few. Spread food wider, add a station near where the thin fish rests, and watch it feed undisturbed. Loaches that abandon the rocks and hang in the current near the surface may be short of oxygen or unwell, and need flow and water checked before the next feed. Because hillstream feeding is so placement-specific, writing the station map into KinsLe with Care Teams, rock by rock, is what lets another keeper reproduce the scatter instead of sprinkling food into the current to vanish.
