A mature tank matters more than a fast welcome
Cherry shrimp settle into tanks that already grow food on their surfaces. A cherry shrimp spends its day grazing biofilm and algae from plants, wood and glass, and a brand-new sterile tank offers almost none of that. Set the aquarium up weeks ahead where you can, seed it with established plants and a piece of moss, and let a gentle film develop on the hardscape before the shrimp arrive. Match the tank's temperature and mineral hardness to the water the shrimp were raised in, since this species tolerates a range of water but hates abrupt change between two points in that range.
Drip acclimation is the introduction
A cherry shrimp should change water at the speed of a dripping tap. Tip the bag into a clean container, then run airline tubing from the tank with a loose knot so tank water drips in slowly, at least doubling the volume over an hour or longer. This slow mixing protects the shrimp's moult cycle: a sudden shift in minerals can force a premature moult the animal is not ready for, which is a common way new shrimp are lost on the first night. When the container water tests close to the tank's, net the shrimp over gently and pour nothing from the container into the aquarium.
Release them at the plants, then leave them alone
Newly released cherry shrimp hide first and graze later, and both are normal. Tip them out beside moss or a dense plant clump so shelter is one step away, then keep hands out of the tank and lights low for the rest of the day. Do not feed on release day: uneaten food fouls a small tank, and the shrimp have biofilm to pick at while they explore. By the following morning you should see a few shrimp out picking at surfaces, and within days the bolder ones will graze in the open while the shy ones work the plant shadows.
Protect the colony's weak moments
A cherry shrimp is most vulnerable just after moulting, when its new shell is still soft. Leave shed shells in the tank, because the shrimp eat them and reclaim the minerals they need. Check that no filter intake can pull in a soft shrimp or a baby — a sponge over the intake solves it — and confirm nothing used in the tank contains copper, which is dangerous for shrimp even in small traces. Keep tankmates peaceful and small-mouthed; even fish sold as calm will happily eat shrimplets. Stable water, changed in small regular amounts, beats large corrective changes every time with this species.
Reading the first week of shrimp behaviour
Settled cherry shrimp graze almost constantly, antennae flicking, and females may soon carry a pale saddle of developing eggs. Shrimp lined up motionless at the surface, repeated frantic swimming, or several failed moults with a pale ring around the body are warnings that the water minerals or oxygen are off. Test the water and compare it with what the shrimp came from before adding anything, and change only a small amount at a time. If deaths continue despite stable, matched water, ask an aquatic specialist or vet to review your parameters rather than dosing the tank on a hunch.
A new colony generates small daily jobs — drip watch, moult checks, a headcount at the moss — and KinsLe Care Teams let a household divide those tasks between people, each one timestamped when finished so nobody repeats or skips a check.
