Clown Killifish Hunt at the Surface, So Scatter There
Clown killifish are built to pick insects from the surface film, with upturned mouths and eyes set high, so scatter-feeding for them happens at the top of the tank, not on the substrate. Take a tiny pinch of micro pellets, finely crushed flake or small live and frozen foods, and release it in several separate spots along the surface rather than one place. Each little patch becomes a hunting ground the fish patrol and pick through, which mirrors how they work along the edges of slow forest streams. Food that sinks quickly is mostly wasted on these fish, so choose items that float or hang in the surface film for a while.
Floating Plants Turn One Surface Into Many Feeding Stations
A bare surface gives a dominant clown killifish male the whole tank to defend, but floating plants break the surface into sheltered pockets where scattered food lodges and waits. Sprinkle pinches between the roots and leaves of floating plants, in the open lanes between plant clumps, and at both ends of the tank. Shyer fish, especially females, will feed inside the plant cover while bolder males work the open water, and everyone eats without a chase. Trim the plants back when they mat too thickly, because food trapped in a dense mat rots where the fish cannot reach it and the surface needs open patches for gas exchange.
Keep the Surface Calm So Scattered Food Stays in Play
Current is the enemy of a good scatter for clown killifish: a strong filter outflow sweeps floating food into a corner or down the intake before these small, unhurried hunters reach it. Baffle the outflow or aim it at the glass so the surface barely moves, then scatter on the still side of the tank. Feed when the surface is calmest, and watch where each pinch drifts so you learn your tank's slow currents and can place food where it lingers. Because the portions are tiny, offer small pinches more often rather than one generous scatter that half sinks uneaten. A feeding pipette helps here too, letting you lay a pinch gently onto the surface film instead of dropping it through and losing it to the depths.
Watch the Whole Group, Not Just the Boldest Fish
The point of scattering for clown killifish is that every fish feeds, so judge success by the quiet fish: the female in the plants and the young male at the far end should both be picking steadily, not hovering empty-bellied below. Clown killifish that repeatedly miss out grow thin behind the head while tankmates round out, and that contrast is your signal to scatter wider or add another feeding pocket. Uneaten food filming over the surface means the pinches were too big; skim it off rather than letting it decay. If a fish stops coming to the surface at all or rests on a leaf gasping, separate observation and a water check come before the next feeding. Noting each feed in KinsLe with Care Teams, including which surface pockets you used, keeps the next feeder from shrinking the scatter back to one corner.
