Cherry Shrimp Care Guide
Cherry shrimp (Neocaridina davidi) are among the easiest and most rewarding freshwater invertebrates you can keep. They are colorful, peaceful, endlessly entertaining to watch, and they earn their keep by grazing on algae and leftover food. This guide covers everything you need to start and maintain a thriving cherry shrimp colony, from tank setup to breeding. For a deeper look at the different color strains and grading, see our companion cherry shrimp color grades guide. Trying to decide between hardy Neocaridina and the more demanding Caridina species?

What Are Cherry Shrimp?
Cherry shrimp are a selectively bred color form of the hardy Neocaridina davidi species. They stay small (around 1 to 1.5 inches), tolerate a wide range of conditions, and reproduce readily in a stable tank. Their adaptability makes them one of the best shrimp for beginners and a favorite for nano and planted aquariums alike.
Tank Setup
A colony can thrive in as little as 5 gallons, though a 10-gallon tank gives a more stable environment and room for the population to grow. A gentle filter is essential, since powerful intakes can suck in shrimplets. Many keepers rely on sponge filters built for shrimp breeding tanks because they provide biofilm for grazing and pose no risk to babies. For a full walkthrough of equipment and aquascape choices, our freshwater shrimp tank setup guide breaks it down step by step.
Substrate and Plants
Inert gravel or sand both work well, though active buffering soils can help if you keep softer-water Caridina later; our aquarium substrate guide compares the options. Live plants are strongly recommended, as they shelter shrimplets, host biofilm, and improve water quality. Easy, low-maintenance choices from our best plants for shrimp tanks list, along with low-light plants and beginner picks from our no-CO2 easy plant guide, are perfect for a shrimp tank.
Water Parameters
Cherry shrimp are forgiving, but stability matters far more than chasing exact numbers. Aim for a temperature of 68 to 78°F, a pH between 6.5 and 7.5, and moderate hardness. Our shrimp water parameters guide explains GH, KH, and TDS in plain terms, and the beginner pH guide is worth a read if you are new to testing. Crucially, never add shrimp to an uncycled tank, because ammonia is lethal to them; if you are unsure, start with our nitrogen cycle guide. Stable, mineral-rich water also matters for clean sheds — see our guide to shrimp molting problems if a shrimp ever struggles to molt.
Diet and Feeding
Cherry shrimp are grazers that constantly pick at biofilm, algae, and decaying plant matter. In an established tank they need very little supplemental food. Offer a small amount of a quality shrimp pellet or blanched vegetables two or three times a week, and remove any uneaten portion within a couple of hours to protect water quality. A mature, algae-friendly tank does much of the feeding for you.
Breeding Cherry Shrimp
If your water is stable and your shrimp are well fed, breeding usually happens on its own. Females carry a clutch of eggs under their tail (often called being "berried") for about three to four weeks before releasing fully formed miniature shrimp. To maximize survival, provide dense plant cover and avoid keeping fish that hunt shrimplets. A species-only tank produces the fastest population growth.
Saddled vs. Berried Females
Learning to read your females helps you know breeding is underway. A "saddle" is a patch of developing eggs visible on a female's back, just behind the head — a sign she is maturing eggs and will soon be ready to mate. Once those eggs are fertilized and moved beneath her tail, she becomes "berried," carrying the clutch until the shrimplets hatch. Seeing saddles and berried females in your tank is the clearest signal your colony is healthy and reproducing.
The Molt, Mate, and Berry Cycle
Breeding is tied to molting. A female typically molts shortly before mating, releasing a scent that signals males she is ready, and mating happens soon after while her new shell is still soft. Because molting is central to reproduction — and a stuck or failed molt can be dangerous — it is worth understanding the process. Our guide to shrimp molting problems explains what healthy molting looks like and how to prevent issues.
Stable Parameters and the Copper Warning
Consistency matters more than chasing exact numbers. Cherry shrimp breed best when temperature and water chemistry stay steady, so small, regular water changes with temperature-matched, dechlorinated water are far safer than large swings. One critical caution: copper is highly toxic to shrimp and their young, so avoid copper-based medications and double-check that any treatments or plant fertilizers are labeled shrimp-safe. Keeping a clean, stable tank is the single biggest factor in raising large numbers of shrimplets.
Raising Shrimplets
Newly released shrimplets are tiny, fully formed versions of the adults and feed almost immediately on biofilm — the thin layer of microorganisms that grows on plants, hardscape, and equipment. A mature, well-established tank with plenty of surfaces and live plants like Java moss gives them the grazing and hiding spots they need. Feed the colony lightly and consistently, and resist the urge to over-clean, since aggressive scrubbing removes the biofilm the babies depend on.
Keeping Your Colony's Color Pure
Cherry shrimp are a selectively bred color form, and over generations a colony can drift back toward duller, wild-type coloring if lower-grade individuals are allowed to breed freely. To keep colors vivid, many hobbyists practice gentle selective breeding — removing off-color or clear shrimp from the breeding population so the brightest individuals pass on their genes. It also means never housing different Neocaridina color strains together, since they interbreed and produce muddy offspring. For more on grades and morphs, see our Neocaridina color guide.
Tank Mates
The safest colony is a shrimp-only tank, but cherry shrimp can coexist with small, peaceful species that won't view them as food. See our list of peaceful Neocaridina tank mates for vetted options. Avoid most cichlids and larger or aggressive fish. If you are still planning your community, our best fish for beginner aquariums guide can help you choose compatible species.
Common Problems
Most shrimp losses trace back to water-quality swings, copper exposure (check medications and fertilizers), or an incomplete cycle. Sudden parameter changes during water changes are a common culprit, so go slow and match temperature. Algae blooms are usually harmless to shrimp and even provide grazing, but if an outbreak gets out of hand, our algae identification and control guide can help. If pest snails hitchhike in on plants, our guide to removing pest snails offers shrimp-safe methods.
Frequently Asked Questions
Are cherry shrimp easy to keep?
Yes. As long as the tank is fully cycled and parameters stay stable, cherry shrimp are one of the most beginner-friendly invertebrates available.
How many cherry shrimp can I keep?
A rough guideline is two to five shrimp per gallon, but a planted tank with good filtration can comfortably support more as the colony grows.
Will cherry shrimp breed in my community tank?
They can, but survival of shrimplets is much higher in a species-only or heavily planted tank where fish cannot eat the babies.
