Biofilm Does Most of the Feeding
A cherry shrimp spends its day picking constantly at surfaces, eating the biofilm — the film of algae, bacteria and microscopic life — that coats everything in an established tank. That grazing is not a supplement to their diet; it is the diet, and it is why a mature, planted tank with wood and leaf litter keeps shrimp thriving with surprisingly little added food. Flakes aimed at fish contribute almost nothing: they are eaten at the surface or decay into the water column. Real variety for cherry shrimp means broadening what grows in the tank and what occasionally lands in it.
Prepared Foods, in Powder-Sized Portions
Offer a dedicated shrimp food — powdered for colonies with many babies, or a small sinking pellet or stick for adults — two or three times a week. Powder has the advantage of spreading across surfaces where tiny shrimplets can reach it. Serve the food in a small glass feeding dish on the substrate: it concentrates the meal in one place, makes an entertaining shrimp pile-up to watch, and lets you lift out leftovers with the dish instead of leaving them to decay into the substrate.
Greens, Leaves and the Slow Foods
Blanched spinach, nettle or courgette, softened until limp, gives the colony a vegetable course a couple of times a month, and shrimp strip a softened leaf down to its veins with enthusiasm. Dried leaf litter — Indian almond, oak or similar shrimp-safe leaves — works differently: as the leaf slowly breaks down it grows exactly the biofilm the shrimp graze, feeding them for weeks from one addition. These slow foods make a colony noticeably more self-sustaining, which matters in a tank meant to run calmly between your visits to it.
Minerals for Every Moult
A shrimp's life is a cycle of moults, and each new shell needs calcium and minerals drawn from food and water. Include a mineral-rich food or a small piece of cuttlebone-style mineral source in the rotation, especially if your water is soft. Repeated failed moults — a shrimp stuck in its old shell, or a white ring around the body followed by death — point to mineral or water problems rather than a lack of meals, and the answer lies in checking the water and the diet's mineral side, not in feeding more.
The Overfeeding Trap
More cherry shrimp die from kindness than from hunger. Uneaten food in a small shrimp tank spikes ammonia and feeds planaria and other pests, while the shrimp themselves keep grazing biofilm contentedly. Feed less than instinct suggests, remove what is untouched after a couple of hours, and skip days freely — a colony in a mature tank will not starve over a weekend. Sudden deaths across the colony mean test the water at once and consider recent changes such as new plants or sprays near the tank; shrimp are sensitive indicators and an aquatic specialist can help if losses continue. Keeping the two-or-three-times-a-week rhythm written into KinsLe Care Teams protects the colony from every household member feeding 'just a little' on the same day.
