Setup
Ghost Shrimp Aquarium Setup, Step by Step

A shrimp tank is easier to build than a fish tank, but it is less forgiving of being rushed. The single highest-impact decision you will make is waiting for a complete nitrogen cycle before the shrimp arrive.
1. Choose the tank and filter
Anything from five gallons up works. Long tanks beat tall tanks because grazing surface matters more than water volume. For filtration, a simple air-driven sponge filter is genuinely the best option for shrimp: it cannot suck them in, it grows biofilm they eat, and it costs almost nothing to run.
2. Substrate and hardscape
Inert gravel or sand is ideal. Active buffering soils drop pH and strip carbonate hardness, which works against ghost shrimp — those substrates are built for soft-water caridina species, not this one.
Add cover: driftwood, cholla, rock caves, and dense moss. Freshly molted shrimp are soft and defenseless for several hours, and a tank without hiding places turns that window into a loss.
3. Plant it
- Java moss and Christmas moss — the best biofilm surface in the hobby
- Java fern and anubias — tough, low-light, attach to hardscape
- Hornwort or guppy grass — fast growers that soak up nitrate
- Floating plants to dim the light and calm the shrimp
4. Cycle the tank
Dose ammonia to about 2 ppm, or use a pinch of fish food, and test every couple of days. The cycle is complete when the tank converts 2 ppm of ammonia to zero ammonia and zero nitrite within 24 hours, with nitrate present. Expect three to six weeks from scratch, or a few days if you seed the filter with media from an established tank.
Do not shortcut this with a bottled bacteria product alone. Use one if you like, but confirm the result with a test kit rather than trusting the label.
5. Age the tank before stocking
Give a newly cycled tank another two to four weeks to grow biofilm and algae before ordering shrimp. A sterile, spotless tank has nothing for them to eat. A slightly grubby one is a shrimp paradise.
