Cherry shrimp: gear and buying guides
The cherry shrimp is a small, hardy and prolific freshwater invertebrate, perfect for a nano tank of 20 L or more. It tolerates a wide range of 18 to 25 °C, often without a heater, but remains extremely sensitive to copper and medications. In colonies, it tirelessly cleans micro-algae off moss and decor.
Profile : 2 to 3 cm as an adult, 20 L minimum for a colony of 10, water between 18 and 25 °C.

Cherry shrimp gear, family by family
-
🍖
Food
A detritivore grazing biofilm and micro-algae, supplemented two to three times a week with dedicated shrimp granules and blanched nettle or spinach leaves. Never overfeed a shrimp tank.
-
🧴
Care & grooming
Copper is lethal even in tiny doses: ban any fertilizer or medication containing it. Moderately hard, stable water supports its molts, the moment when it is most vulnerable.
-
🎾
Toys & enrichment
Java moss, marimo balls and catappa leaves multiply grazing surfaces. Hiding places are vital for freshly molted females and juveniles.
-
🏠
Bedding & habitat
A nano tank of 20 L or more, well matured and densely mossy, kept species-only or with peaceful micro-fish. Almost all medium-sized fish eat the juveniles.
-
🧳
Travel & safety
Transport in a bag with a strand of moss to cling to; it travels very well. One-hour drip acclimation is mandatory, as parameter shocks trigger fatal molts.
-
🧰
Accessories
A sponge filter or an intake guard on the pump to avoid sucking in juveniles, GH/KH tests and a drip acclimation kit. A complete nano tank can be equipped for around 50 to 100 euros.
🍖 Feeding a Cherry shrimp: algivore diet, frequency, mistakes
Feeding a Cherry shrimp: diet and habits
The Cherry shrimp is an algae grazer and detritivore: tank algae, spirulina wafers and blanched vegetables as top-up. It feeds at the bottom: serve sinking wafers, in amounts eaten within two minutes at most — everything else ends up as nitrates.
Frequency and variety
One or two small feeds a day for adults, with a weekly fasting day that costs it nothing — overfeeding remains the top cause of tank pollution. In a group of 10 or more, check everyone reaches the food: dominants serve themselves first. Alternate dry, frozen and blanched greens (courgette, spinach) across the week.
The costly mistakes
Beware copper in foods and treatments: lethal to shrimp even at “fish-safe” doses. Avoid discount flakes that fall apart on contact with water: a serious brand costs only a few euros more per year. The rest of the profile is on the full Cherry shrimp profile.
Quick answers
- How often should a Cherry shrimp be fed?
- One or two small daily feeds eaten within two minutes, plus one fasting day a week. In doubt, underfeed: the water will thank you.
- What food suits a Cherry shrimp?
- An algae grazer and detritivore: tank algae, spirulina wafers and blanched vegetables as top-up — served in sinking form to reach its bottom zone.

🧳 Transporting a Cherry shrimp: bagging, acclimatisation, moving
Bringing home or moving a Cherry shrimp
A 3 cm Cherry shrimp travels in a double bag — one-third water, two-thirds air — inside a cool box or opaque bag: darkness soothes, insulation protects from swings away from its 18 to 25°C comfort zone. Add a clump of moss in the bag: shrimp cling to it and travel better.
Acclimatisation: the critical step
Start with 20 minutes of floating, bringing the bag water to tank temperature, then add tank water drop by drop over an hour — the species is sensitive to parameter swings, and release with a net without pouring bag water into the tank. In this species, a botched transfer is paid for in bouts of failed molts during parameter shocks. The first day happens lights-off — darkness defuses the sometimes muscular curiosity of the residents.
Moving an entire aquarium
A successful move rests on three precautions: fish in covered buckets, the filter never dried out (damp cool box — it houses your bacteria), and a same-day restart using original water saved in jerrycans. The tank itself travels EMPTY: glass stressed by a few leftover litres cracks at the first corner.
Quick answers
- How long can a Cherry shrimp handle transport?
- Properly bagged, a Cherry shrimp lasts several hours unharmed — and up to a day in a professional oxygenated bag. The real battle, past two hours on the road, is holding the temperature.
- How do you acclimatise a Cherry shrimp safely?
- Float the bag 20 minutes, add tank water gradually over 30 to 60 minutes, release with a net, lights off the first day — and never pour bag water into the tank.

🧰 Accessories for a Cherry shrimp: tests, upkeep and budget
Water tests: your dashboard
A drop-test kit (€15-30) is THE first accessory for a Cherry shrimp tank: NO2 and NO3 weekly, GH-KH-pH at any doubt. Then come the net sized for 3 cm, the substrate siphon and the dedicated bucket — never the cleaning one, whose detergent traces contaminate the water.
The Cherry shrimp specifics
a fine sponge pre-filter on the intake, or the colony ends up touring the pump; a battery backup air pump: at full stocking, a filtration failure is measured in hours; plant tongs and weighted wafers to feed the bottom without scattering everything.
The full budget, no surprises
An equipped 20 L setup (tank, filter, heater, lighting, substrate, decor, tests): expect €100 to 250 upfront, then €10 to 25 a month (food, electricity, conditioner). Second-hand often halves the tank price — only the filter and heater deserve to be new. Details on the full Cherry shrimp profile.
Quick answers
- Which accessories are essential for a Cherry shrimp tank?
- Drop tests, siphon, net, dedicated bucket, an independent thermometer: the whole kit stays under €60.
- What budget for keeping a Cherry shrimp?
- €100 to 250 to set up an equipped 20 L tank, then €10 to 25 a month in routine costs.
