Watching shrimp behaviour without disturbing them
A cherry shrimp carer should begin each visit by simply looking, because a healthy colony grazes almost constantly, picking over leaves, moss and wood with bright red females easy to spot and paler males moving between them. Ask the carer to spend a few quiet minutes noting shrimp spread across the tank rather than clustered at the surface, and to look for newly moulted pale shells on the substrate, which are normal and should be left where they lie.
Warning signs for cherry shrimp are specific: many shrimp lining up at the waterline, frantic swimming loops around the tank, or several deaths found on the same day. Those patterns can follow a contaminant or a sudden water shift, and the carer should message you immediately rather than perform a large emergency water change, which can worsen the swing for the survivors. Evaporation in a small shrimp tank concentrates minerals, which is why your pre-trip note should say whether a top-up is wanted and with which labelled bottle.
The strictest rule on the shrimp list is chemical: no fly spray, air freshener, scented candle or cleaning spray used in the tank's room, and no hands in the water after using lotions or insect repellent. Shrimp react to traces that fish tolerate, and holiday homes get cleaned by helpful people. Leave that warning in large print on the tank, and ask the carer to open a window instead of spraying anything if the room needs airing.
Filtration and the danger of a strong intake
A cherry shrimp tank usually runs a gentle sponge filter or a guarded intake, and the daily check is that bubbles rise steadily or flow continues without pulling at the moss. Baby shrimp are tiny enough to be drawn toward an exposed intake, so the carer should confirm the foam guard or mesh you fitted is still in place and has not slipped during the week.
If the filter stops, the carer should check the plug and air line first and follow your written note, because sponge filters often fail at the pump or a kinked tube rather than in the tank. The carer must not rinse the sponge under a tap during your holiday; that sponge holds the colony's grazing surface and much of the tank's stability. A squeeze in removed tank water is a job for your return unless you have specifically taught it beforehand.
Feeding a colony that mostly feeds itself
Cherry shrimp feed themselves from biofilm and algae for much of the day, so holiday feeding should be far lighter than a carer expects. Leave a few labelled portions of the shrimp's usual food for set days only, not every day, and make clear that an algae wafer fragment left uneaten after a few hours means the next portion is skipped. Rotting food in a shrimp tank fouls water that a small colony cannot afford.
If the tank has live plants and light on its timer, the colony will find plenty between portions. Note on the list which day each portion belongs to, so a missed visit does not become a double feed the next day.
A short daily report keeps the colony safe
Ask the cherry shrimp carer for a brief daily note: shrimp active and grazing, temperature steady, filter running, food given or skipped, and anything found dead or behaving oddly. A photo through the front glass every few days lets you judge colour, water clarity and plant growth from wherever you are, and gives the carer confidence that small changes have been seen by you.
Shrimp care on holiday is mostly disciplined restraint, repeated daily. KinsLe Care Teams supports that rhythm by letting you assign care duties for your shrimp to your carer, with each completed check marked by a timestamp you can review.
