Crystal Red Shrimp

The Red and White Stripes are what helps identify the Crystal Red Shrimp (also known as CRS) from other dwarf shrimp types. When maintained correctly, Crystal Red shrimp can be one of the easiest Caridina shrimp to keep which will lead to continuous breeding.

Misinformation, misguidance, poor preparation, and wrong handling contribute to the low population of this tank-bred shrimp.

In the current shrimp hobby, Crystal Red shrimp are 99.9% tank bred and are you are very unlikely to find the common Crystal Red Shrimp in the wild in the exact form.

This guide will help new and experienced hobbyists to keep and breed Crystal Red Shrimp. We've divided this guide into five crucial topics to understand better how to correctly and effectively breed the Crystal Red Shrimp. The five sections are Tank Requirements, Housing, Feeding, Cohabitation, and Breeding & Grading.


Crystal Red Shrimp can be quite delicate and thus, difficult to breed, if a proper tank with the correct soil, remineralizer, and temperature are not kept.

Below are the key factors for healthy tank requirements for breeding Crystal Red Shrimp. 

a.) Tank's Temperature - The best tank temperature for Crystal Red Shrimp is between 60 to 72°F. The optimum level is around 70°F and a good rule of thumb is to keep the water on the cooler side because higher temperatures can lead to bacterial infections and faster deaths.

This temperature range is lower than other shrimp types. Putting other dwarf species together is very tricky because other shrimp species (neocaridina) typically like warmer waters and use different remineralizers.

Gestation period, maximum size, color, and life-span of the Crystal Red Shrimp all rely on the proper pH level of water used in the tank as well as proper tank setup.

Use an active substrate that helps stabilize the water tank's pH to its optimum level at 6.2 to 6.5ph.

c.) Water Chemistry - An aquarium usually has biological waste, which accumulates inside it caused by uneaten food, waste from shrimp, wood, dying plants, bacteria, and algae. These organic wastes break down into by-products. These by-products include ammonia, nitrates, and nitrites.

To achieve a perfect level that can make Crystal Red Shrimp thrive, the levels of these three by-products should be at the following levels:

Nitrite: 0ppm
Ammonia: 0ppm
Nitrate: less than 20ppm

Changing your shrimp tank water at least once a week is what controls the level of these by-products from reaching dangerous levels for our crystal red shrimp. Maintaining the maximum level required for each by-product is crucial.
