Caring for cherry shrimp day to day is an exercise in restraint. A colony of these inch-long red neocaridina shrimp feeds itself largely on biofilm, algae, and decaying plant matter, so the keeper's daily work is observation: a few minutes of watching at the glass tells you more about this tank than any chore would. Expect the whole routine to take less time than making coffee.
Morning: read the colony at the glass
Look first for activity. Healthy cherry shrimp graze constantly, picking at plants, sponge filters, and the substrate with their small claws. Spot the berried females carrying yellow-green eggs under their tails, and check for shrimplets — specks the size of sesame seeds — grazing near the glass. A morning when many shrimp hide or sit motionless is information: something about the water has shifted, and it deserves a test rather than a water change made blindly. A rough headcount matters too — new shrimplets appearing most weeks is a clear sign the colony is settled and content.
Feeding: less, and less often, than you think
Most days need no food at all. Drop in a small pinch of shrimp pellet, a piece of blanched spinach, or a fragment of algae wafer every other day, and remove what remains after a couple of hours. In a mature planted tank the colony can go longer. Overfeeding is the classic cherry shrimp mistake: uneaten food fouls a small volume of water fast, and shrimp are far more sensitive to that than to a missed meal.
Water and equipment: stability above all
Top off evaporation with treated water and glance at the filter — a sponge filter or a sponge-guarded intake is essential, because unguarded intakes swallow shrimplets. Shrimp molt regularly, and an empty white shell on the substrate is a success, not a death; leave molts in the tank, as the colony eats them for minerals. What shrimp cannot handle is swing: large, sudden water changes with mismatched water are a far bigger daily risk than a slightly overdue one.
The weekly frame
Once a week, do a small water change — a modest fraction, dripped or poured back slowly — and test the basics. The colony will repay steady, boring care by breeding steadily.
