A school that lives at the surface and startles as one
Norman's lampeyes are small killifish with a glowing blue eye ring, kept in groups and spending most of their lives in the top layer of the water under floating cover. That one fact shapes their whole cleaning routine. Work at the surface is work in their living room: a lid lifted suddenly, a net or siphon arriving from above, or a shadow crossing the tank can send the school darting — and lampeyes jump. Cleaning therefore starts before any water moves, with the room calm, movements slow, and a cover ready to slide over any opening the moment your hands leave the tank. A predictable weekly rhythm helps more with this species than with most, because the school learns the routine and panics less each time.
Lids, floating plants, and the top layer
Floating plants are not decoration in a lampeye tank; they diffuse the light, mark the surface as safe, and give eggs and fry shelter. During cleaning, thin them only when they blanket the whole surface and block feeding and gas exchange, and even then remove a portion, not the mat. Check plant roots and the underside of floaters for trapped debris, lifting and swishing them gently in removed tank water. Keep the lid itself in the routine: wipe condensation and algae film from its underside so light reaches the plants, and inspect the corners and cut-outs where a jumping fish could find a gap. Eggs are sometimes laid among roots and fine leaves, so treat any plant you remove as potential nursery material and look before discarding.
Water changes beneath a nervous school
Small, frequent partial changes suit lampeyes far better than large ones, keeping their soft, slightly warm water steady. Draw water from mid-depth with the siphon kept low and slow, working the open substrate in short passes while the school gathers at the far end, and never chase debris into their refuge corner. Pour refills in slowly over floating plants or a diffuser so the surface does not boil — a violent refill reads as an attack from above to a surface species. Rinse sponge or hang-on filter media in removed tank water during the same session, and keep the filter outlet from creating a strong surface current, which lampeyes dislike and which scatters their food. Afterwards, watch the school regroup: tight, high, silent hovering means they are still unsettled, while loose cruising with males flashing their fins means the tank feels normal again.
Feeding fallout and the lower levels
Lampeyes take tiny foods at the surface, and what sinks past them feeds the substrate instead. That fine fallout is the main cleaning load in their tank: siphon the open bottom weekly, clear the filter intake of plant fragments, and wipe the front glass with a soft pad in slow strokes from the bottom up, so startled fish always have a calm direction to move. Avoid bright torches or tapping during the session. If shrimp or small bottom fish share the tank, their waste adds up in the same corners, so let your siphon pattern follow those resting spots rather than a fixed grid.
When the routine itself needs a review
Lampeyes losing their eye shine, schooling tighter week after week, or leaving food they once rushed are early hints that waste is outpacing your cleans or that sessions have become too disruptive. Sudden losses after maintenance usually trace back to a gap in the lid or a refill poured too fast, so review the session, not just the water. If several fish show ragged fins, gasping, or white spots despite steady water and gentle handling, get advice from an aquatic veterinarian or fish health specialist rather than deep-cleaning harder. Logging each job in KinsLe via Care Teams — lid check, plant thin, water change — with a timestamp for whoever completed it gives this easily startled school the same quiet routine from every pair of hands.
