Cherry Shrimp Care: The Only Guide You Actually Need

Cherry shrimp (Neocaridina davidi) are the gateway drug of the aquarium hobby. You buy ten of them for your planted tank because they eat algae, and six months later you have hundreds and are seriously considering dedicating an entire rack to shrimp breeding. They are ridiculously easy to keep, endlessly entertaining to watch, and they come in every color from fire engine red to electric blue. Here is everything you need to know.

Why Cherry Shrimp Are Perfect for Planted Tanks

Cherry shrimp are the ideal planted tank inhabitants because they actively clean your aquascape. They eat algae off leaves, graze biofilm from hardscape surfaces, consume decaying plant material, and pick up uneaten fish food. A healthy colony of cherry shrimp is basically a self-deploying cleanup crew that also happens to look amazing against a green carpet.

Color grades: Cherry shrimp come in grades from lowest to highest: Cherry (translucent with red spots), Sakura (mostly red with some clear areas), Fire Red (solid red, no clear patches), Painted Fire Red (deep opaque red including legs and underbelly). Higher grades cost more but breed true if you keep the colony pure.

Tank Setup

Tank Size

A colony can thrive in as little as 5 gallons, though 10 gallons gives you more stable water parameters and room for the colony to grow. Use our tank size calculator to figure out volumes for different tank dimensions.

Substrate

Inert substrates (sand, gravel) or buffering aquasoils both work. Aquasoil buffers pH slightly acidic, which shrimp appreciate. Dark substrates make red shrimp pop visually — a black sand or dark brown aquasoil is the best backdrop for showcasing color.

Filtration

Sponge filters are king for shrimp tanks. They provide biological filtration, gentle flow, and a massive surface area for biofilm that shrimp graze on constantly. If you use a hang-on-back or canister filter, cover the intake with a sponge pre-filter to prevent baby shrimp from being sucked in.

Plants

Heavily planted tanks are shrimp paradise. Mosses (Java moss, Christmas moss, flame moss) are especially valuable — they trap food particles and provide countless hiding spots for baby shrimp. Floating plants like salvinia or frogbit add shade that shrimp prefer.

Biofilm heaven: Add Indian almond leaves (catappa leaves) or alder cones to your shrimp tank. As they decompose, they grow a layer of biofilm that shrimp graze on 24/7. One leaf per 5 gallons, replaced monthly.

Water Parameters

Parameter	Ideal Range	Notes
Temperature	68-76F (20-24C)	Higher temps speed metabolism and shorten lifespan
pH	6.5-7.5	Stable pH matters more than exact number
GH	6-8 dGH	Need minerals for molting
KH	2-5 dKH	Buffers pH stability
TDS	150-250 ppm	Proxy for overall mineral content
Ammonia/Nitrite	0 ppm	Any detectable amount is dangerous
Nitrate	Under 20 ppm	Keep low with water changes and plants

Copper kills shrimp. Even trace amounts of copper are lethal to cherry shrimp. Check your tap water for copper, avoid medications containing copper sulfate, and never use copper-based algaecides in a shrimp tank.

Feeding

Cherry shrimp are not picky eaters. In a well-established planted tank with biofilm and algae, they barely need supplemental feeding. For a colony of 20 to 30 shrimp in a 10-gallon planted tank, feed supplementally 2 to 3 times per week:

Blanched vegetables: Zucchini, spinach, kale (remove after 12 hours)
Shrimp-specific foods: Shrimp King, GlasGarten, or Hikari Shrimp Cuisine
Protein occasionally: Snowflake food, mulberry leaves, or dried bee pollen
Calcium sources: Cuttlebone pieces, mineral rocks, or crushed coral in the filter

Breeding

Cherry shrimp breed prolifically when conditions are stable. You do not need to do anything special — just provide good water quality, food, hiding spots, and slightly warmer temperatures (72 to 76 degrees). A female carrying eggs (berried) will hold them under her swimmerets for 28 to 35 days before they hatch as miniature versions of adults. No larval stage, no special care needed.

Colony Growth Timeline

Month 1-2: Shrimp acclimate, explore, and you see the first berried females
Month 3-4: Baby shrimp appear. Colony starts growing noticeably
Month 6: Colony doubles or triples from original purchase
Month 12: You have more shrimp than you know what to do with

Population control: Cherry shrimp self-regulate population based on available food and space. In a balanced planted tank, the colony will stabilize at a sustainable density. If you want to control numbers, add a small group of dwarf fish (like celestial pearl danios) that will eat some babies.

Common Problems

White ring of death: A white band around the body indicates a failed molt, usually from insufficient GH (mineral content). Increase GH to 6 to 8 dGH.
Shrimp dying after water changes: Temperature and TDS swings during water changes shock shrimp. Match new water temperature exactly and change no more than 15 to 20 percent at a time.
Color fading: Low-grade genetics, stress, or poor diet. Feed color-enhancing foods and cull translucent shrimp if you want to improve the colony's color intensity over generations.
Hiding and not active: New shrimp hide for 1 to 2 weeks while acclimating. Also check for predators — even peaceful fish may stress shrimp into hiding.

Cherry shrimp are the best value in the aquarium hobby. Ten dollars worth of shrimp will give you an endlessly entertaining, self-sustaining colony that actively maintains your planted tank. Start with a group of 10 to 15, keep the water stable, and watch nature do its thing.
