🎾Enriching a Cherry shrimp tank: hardscape, shoal and occupation
Cherry shrimp : Java moss, marimo balls and catappa leaves multiply grazing surfaces. Hiding places are vital for freshly molted females and juveniles.
In short: 2 to 3 cm as an adult, 20 L minimum for a colony of 10, water between 18 and 25 °C. A peaceful, gregarious invertebrate that grazes the decor in a colony and is kept ten or more strong. Copper is lethal to it even in tiny doses: ban any fertilizer or medication containing it, and acclimate it drip by drip.
Hardscape designed for its swimming zone
The swimming zone dictates the decor: a Cherry shrimp moves at the bottom, so soft sand (never sharp gravel), hollow roots and open patches to sift make up its ground. An aquarium’s enrichment is its hiding places and its currents — not fluorescent ornaments.
Group life: the first enrichment
From 10 individuals up, the Cherry shrimp becomes itself again: hierarchies settling, displays, coordinated swimming — in small numbers it lives in chronic stress and loses its colours — group size is the species’ first “toy”, before any decor purchase.
Food as occupation
Turn every meal into exercise: a weighted courgette slice keeps the Cherry shrimp busy for hours, with the feeding spot moving day to day — foraging is its real “toy”.
Frequently asked questions
How many Cherry shrimp should be kept together?
10 minimum, more if the tank allows: it is a shoaling species, and numbers shape its behaviour and colours alike.
How do you enrich a Cherry shrimp tank?
Through layout above all: decor designed for its living zone (at the bottom), meals served in varied ways and a complete group — gadgets add nothing.
The guides that apply to you
- Low-tech aquarium: the method to save money without shortchanging the fish
The low-tech aquarium bets on plants rather than technology: no CO2, sometimes no heater, reduced maintenance. Budget, suitable species and setup method.
- Floating aquarium plants: which ones to choose and why?
Water lettuce, duckweed, salvinia: which floating plants should you choose for your aquarium, and what benefits do they bring?
- Should you regularly change the aquarium's decor?
Rotating rocks, plants or hiding spots can stimulate fish used to a fixed layout — but a poorly handled change can also destabilise an established territory. How to tell the difference.
- Mirror for a betta: useful stimulation or needless stress?
A mirror shown to a betta triggers an impressive display, but this stimulation must stay brief and rare to avoid tipping into chronic stress.
