The Quick Catch: Cherry Shrimp (Neocaridina davidi)

Of all the freshwater invertebrates I’ve kept over the years, Neocaridina davidi — commonly known as Cherry Shrimp — are hands-down the most enjoyable. Hardy, colorful, endlessly active, and easy to breed, they’ve become a staple in my fishroom. Whether you’re a seasoned aquarist or just dipping your toes into the hobby, these little shrimp bring life and functionality to just about any tank.

I started keeping Neocaridina mostly out of curiosity, picking up a few bright red shrimp on impulse from a local store. At first, I wasn’t expecting much beyond some added color and cleanup help, but within a few months, I was hooked. They multiplied quickly, displayed a wide range of quirky behaviors, and seemed to thrive with minimal fuss. I now keep several color varieties across multiple tanks — red, blue, yellow, green, and even some wild-type — and I still enjoy them as much as I did that first batch.

Tank setup for Neocaridina is pretty simple, but there are a few things I’ve learned that really make a difference. A mature tank with stable parameters is key, as shrimp are more sensitive than fish to sudden changes. I prefer to use sponge filters for gentle water flow and biofilm development, and I always add plenty of live plants, mosses, and leaf litter — these provide surface area for biofilm and algae to grow, both of which are important food sources for shrimp.

One thing I like to add to all my shrimp tanks is Süsswassertang. It might not be the flashiest plant, but it’s a powerhouse when it comes to boosting the micro-ecosystem in a small tank. It dramatically increases available surface area for biofilm and detritus to accumulate — both critical food sources for shrimp, especially babies. I’ve added it to nearly all my colonies at this point, and it’s made a noticeable difference in how well the young shrimp do.

When it comes to feeding, Neocaridina shrimp aren’t picky, but I do have my preferences. The staple in all of my tanks is Sera Shrimp Natural pellets — they hold their shape well, don’t cloud the water, and the shrimp go absolutely nuts for them. I also like to rotate in Miyagi Shrimp Sticks and Kat’s Aquatics Shrimp Sticks for variety and added nutrients.

One of the most important and often overlooked aspects of shrimp care is calcium. Shrimp need calcium to molt properly and maintain strong, healthy exoskeletons. Without enough calcium, they can suffer from molting problems, which is one of the leading causes of shrimp death in the hobby. I’ve found Kat’s Aquatics Calcium to be one of the best sources available — it’s reliable, shrimp-safe, and does not dissolve in the water or raise pH or hardness. Since I started using it regularly, my shrimp have molted more cleanly and I’ve seen better survival rates, especially in younger shrimp.

Breeding Neocaridina davidi is one of the most satisfying parts of keeping them. As long as water conditions are stable and there’s plenty of biofilm and cover, they breed readily on their own. Females carry eggs under their abdomen (known as being “berried”) for about 3–4 weeks before releasing fully formed miniature shrimp into the tank. These tiny shrimplets require no parental care but benefit greatly from a mature tank full of microfauna, biofilm, and fine-leaved plants. It’s not uncommon for a single berried female to kickstart a booming colony in just a few months.

One important note for those looking to breed for color: if you mix different color varieties in the same tank, their offspring will usually revert to wild-type colors — typically shades of brown or clear. To maintain bright, consistent coloration across generations, it’s best to keep one color variety per tank.Overall, Neocaridina davidi are a great choice for anyone looking to get into shrimp keeping or expand their current lineup. They’re colorful, interactive, and rewarding to care for. Plus, once you get their environment dialed in, they’re incredibly easy to breed — meaning you’ll always have a thriving colony to enjoy. Whether you keep them as a display or a functional cleanup crew, Cherry Shrimp are a small species with a big impact.
