Arrival day and week one for cherry shrimp
A cherry shrimp's settling routine begins before it touches its new water. These small shrimp are far more sensitive to sudden changes in water chemistry than most fish, so acclimate them slowly — ideally by dripping tank water into their container over an hour or more — and then net them in gently, leaving the shipping water out of the tank. Once released among plants and moss, expect them to vanish, and let them.
The first week for cherry shrimp should involve almost no intervention. Keep lights on their normal timer so algae and biofilm grow steadily, skip feeding or offer the tiniest amount, and do not chase a headcount. Shrimp wedged in moss are grazing and settling, and a newly introduced group that is invisible for days is behaving normally, not failing.
Feeding a colony that mostly feeds itself
Cherry shrimp eat continuously, grazing biofilm, algae, and decaying plant matter from every surface, so the feeding routine in their first month is restraint. Offer a small prepared feeding only a few times a week, sized so it is gone within a couple of hours, and remove what remains. Overfeeding is the fastest way to ruin the water a new colony is settling into, and shrimp tanks suffer far more from generosity than from scarcity.
Variety supports molting and breeding as the month progresses. A piece of blanched vegetable, a leaf left to soften in the water, and surfaces of wood and stone left unscrubbed all give cherry shrimp different grazing. If shrimp swarm a feeding eagerly, the tank's natural grazing may be thin and portions can rise slightly; if food sits ignored, the tank is feeding them and your offerings should shrink.
Water changes and tank work, done the shrimp-safe way
Keep a cherry shrimp's first-month water changes small, gentle, and boringly consistent. Replace a modest portion at a time with water matched closely in temperature, pour it in slowly rather than dumping it, and avoid deep gravel vacuuming — baby shrimp and the biofilm they need both live in the substrate and the filter. A sponge over the filter intake is essential settling equipment, since new shrimplets are small enough to be drawn in.
Molting is the vulnerable rhythm underneath the routine. A cherry shrimp that hides for a day or two is often mid-molt, and the shed skins left on the moss should stay in the tank, because the colony eats them and reclaims the minerals. Stable water matters more during this month than perfect numbers, and repeated large changes chasing an ideal reading unsettle shrimp far more than a steady, near-enough tank.
Reading a cherry shrimp colony at the end of month one
A settled first month shows in behavior: cherry shrimp grazing openly across the moss and glass in daylight, females carrying the yellow saddle that precedes eggs, and empty molts appearing regularly. A colony still hiding constantly at week four suggests the light is harsh, fish tankmates are hunting them, or the water is swinging between changes.
Losses in the first days after arrival can happen with stressed individuals, but ongoing deaths, shrimp trying to climb out, or many shrimp crowded at the surface point to a water problem needing tests and prompt advice from an aquatic specialist or veterinarian if the cause is not obvious. In shrimp keeping, the correct response is almost always slower and smaller than instinct suggests.
Most cherry shrimp care is remembering not to do things, which is exactly what a shared schedule protects: KinsLe Care Teams can hold the colony's few small jobs — a light feeding, a gentle water top-up, a headcount — as assigned tasks marked complete, so no shrimp gets fed three times by three kind people.
