Starting a Nano Planted Shrimp Tank: A Beginner's Guide

May 02, 2026 · Maren Marine

A planted nano full of cherry shrimp is one of the most charming, low-footprint tanks you can keep — a living jar of color on a desk. It's beginner-friendly too, as long as you respect one thing: shrimp need stable water. Here's how to set one up right.

Why shrimp are a great first freshwater tank

Neocaridina shrimp (cherry, blue, yellow and more) are hardy, colorful, breed readily, and thrive in a small low-tech planted setup — no CO2 required. They graze algae and biofilm all day and add almost no waste. The catch: they're sensitive to swings and to copper, so a steady, well-cycled tank is the whole game.

What you'll need

A 5–10 gallon tank — small is fine here
A gentle filter (sponge filters are perfect — no risk of suction)
Substrate and a modest light for plants
RO/DI water + a shrimp remineralizer for stable, controlled parameters
Plants, a bit of hardscape, and patience while it cycles

The gear

Filtration & substrate

Hygger Nano Sponge Filter · $38
Gentle, shrimp-safe filtration with loads of surface for beneficial bacteria — and zero chance of sucking up a baby shrimp.

Tropica Aquarium Soil · $35
A gentle, plant-feeding soil that's easy to start with — great for a low-tech shrimp planted tank.

Water — the part that matters most

Salty Shrimp GH/KH+ Remineralizer · $25
Neocaridina want specific, stable mineral levels. Starting from RO/DI and remineralizing to target gives you full, repeatable control — the single best thing you can do for shrimp.

Seachem Prime Dechlorinator · $15
If you use tap water, this neutralizes chlorine and chloramine that are lethal to shrimp.

Bacteria Starter · $18
Speeds your cycle so the tank is biologically ready before any shrimp go in.

Plants and the setup

Shrimp adore mosses and easy plants — java moss, anubias, crypts — which give them surface to graze and shelter for babies. Plant moderately from the start, add a little wood and stone for structure, and run a light on a consistent timer. This is classic low-tech planted keeping; the fundamentals are all in our planted basics guide.

Straight talk — Cycle the tank fully and let it mature for a few weeks of stable readings before adding shrimp — and acclimate them very slowly, over an hour or more, when they arrive. Shrimp don't tolerate sudden changes the way a hardy fish might. The patient setup is the one that ends up overrun with happy shrimp.

Reefer's tip — Never use anything with copper near a shrimp tank — many fish medications and some plant ferts contain it, and it's lethal to inverts. Check labels for 'invertebrate safe.'

Wondering whether to add CO2 down the road? Most shrimp tanks stay happily low-tech — but here's the low-tech vs. high-tech breakdown if you catch the bug. Browse gear in Planted Aquariums and Water Treatment.
