Cherry Shrimp Care Guide

Cherry shrimp are where most people start in the freshwater invertebrate hobby, and for good reason. They are hardy, colorful, endlessly entertaining to watch, and they breed on their own once the tank is stable. This guide covers everything from tank size to breeding so you can get a thriving colony on the first try.

What you need

Setting up a cherry shrimp tank is refreshingly simple. The non-negotiables are a cycled tank, gentle filtration, and stable water. Everything else is a bonus.

A sponge filter is the single most important piece of gear for a shrimp tank. It provides biological filtration without an intake tube that could suck in baby shrimp, and the sponge surface grows the biofilm that shrimp graze on all day.

Tank size and setup

A 5 gallon tank is the practical minimum, and a 10 gallon is even more forgiving because the larger water volume resists swings in temperature and chemistry. Cherry shrimp are not strong swimmers, so a wide footprint matters more than height.

Cycle the tank fully before adding any shrimp. That means running the filter for two to four weeks until ammonia and nitrite both read zero. Shrimp are far more sensitive to ammonia than most fish, and adding them to an uncycled tank is the most common way beginners lose a colony.

Water parameters

Cherry shrimp are tolerant, but stability beats perfection. Aim for a temperature of 65 to 78°F, a pH between 6.5 and 8.0, and a general hardness of 6 to 12 dGH. The hardness matters most — shrimp need minerals like calcium to molt their shells successfully.

Avoid sudden changes. A slow drift is fine; a fast swing during a water change is what causes failed molts and deaths. Keep water changes small and frequent rather than large and rare.

Diet and feeding

Cherry shrimp are omnivores that spend their day grazing biofilm and algae off every surface. In an established tank you barely need to feed them. Two or three times a week, offer a small amount of a quality shrimp food and remove anything uneaten after a couple of hours.

Blanched vegetables like spinach or zucchini are a welcome treat, and Indian almond leaves slowly break down into a biofilm buffet the whole colony will swarm.

Tank mates

The honest answer is that cherry shrimp are happiest in a species-only tank. If you do want tank mates, stick to small, peaceful, non-predatory fish such as chili rasboras, pygmy corydoras, or otocinclus.

Even gentle fish will pick off baby shrimp, so a dense thicket of Java moss gives the babies a place to hide and dramatically improves how many survive to adulthood.

Breeding

If your shrimp are happy, they will breed without any intervention. A female carrying eggs under her tail is called "berried," and she will fan the eggs for about three to four weeks before tiny, fully formed shrimplets hatch.

There is no larval stage to worry about — the babies are miniature adults that immediately start grazing. The key to a growing colony is simply not vacuuming up the babies and giving them biofilm and moss to hide in.

Common diseases

Healthy cherry shrimp rarely get sick. The two problems you might see are failed molts, usually caused by low GH or unstable water, and bacterial or fungal infections that show as white patches. Both are best prevented through stable parameters and clean water rather than treated with medication, since most shrimp-safe treatments are limited.
