Part of the Shrimp

Freshwater dwarf and algae-eating shrimp kept as peaceful, hardworking cleanup crews and colorful centerpieces in planted aquariums. Most are small, sensitive to copper and poor water quality, and best kept in groups.

Minimum

Planted nano tank

5 gal (≈ 19 L), cycled, planted

Neocaridina davidi 'red cherry' is the easiest dwarf shrimp — pH 6.8–7.8, GH 6–10, sponge filter. Start with 10+ in a cycled planted nano; populations expand quickly with stable parameters.

Recommended habitat
Recommended

Planted colony tank

10–20 gal, planted, moss + IAL

A 10–20 gal planted tank with java moss, almond/oak leaves, and sponge filtration. Selective culling for deep red ('Fire Red', 'Painted Fire Red') is straightforward at this scale.

Aquascape colony / breeding tank

20+ gal, planted aquascape

A larger aquascape with dense plant cover and stable water chemistry produces colonies in the hundreds. Species-only for line-breeding; do not mix with other Neocaridina morphs.

Life & growth stages

How this animal changes through its life — each stage often has its own care, diet and space needs.

Larva

Most marine invertebrates hatch into microscopic planktonic larvae (such as the zoea of crustaceans or the bipinnaria/veliger of echinoderms and mollusks) that drift and feed in the water column. The larva looks nothing like the adult and undergoes major reorganization.

Photo coming soon
Juvenile

After settling out of the plankton, the juvenile takes on a recognizable miniature of the adult body plan — a tiny shell, a small star, or a translucent shrimp. Crustaceans grow by molting, shedding the exoskeleton to enlarge.

Adult stage
Adult

Adults reach full size and reproductive maturity with the species' mature shell, shape, or coloration. Many continue to molt or grow throughout life, and some show sex differences in size or claw/appendage shape.

Color & pattern variants

Natural variants occur in the wild; selectively bred (man-made) variants were developed in captivity.

Selectively bred (man-made)
Red cherry / Fire red / Painted fire redrepresentative

Red cherry / Fire red / Painted fire red

CommonBeginner

A graded series of selectively bred red Neocaridina, from translucent-patchy Red Cherry up through solid Fire Red to opaque, leg-included Painted Fire Red. The hobby's foundational shrimp.

Tip: Cull pale/translucent individuals to hold grade over generations; on a dark substrate and varied biofilm diet the reds intensify markedly.

Yellow (Golden Back / Neon Yellow)representative

Yellow (Golden Back / Neon Yellow)

CommonBeginner

A yellow Neocaridina line; Golden Back shows a bright dorsal racing-stripe while Neon Yellow glows under good light. A bright, easy-keeping alternative to reds.

Tip: Don't house alongside red, blue or green Neocaridina—they all interbreed and revert offspring to muddy wild-type brown within a few generations.

Blue (Blue Dream / Blue Velvet)representative

Blue (Blue Dream / Blue Velvet)

CommonBeginner

Selectively bred blue lines: deep solid Blue Dream and the slightly lighter Blue Velvet. Among the most sought-after color forms for planted tanks.

Tip: Blue coloration is somewhat mood/stress-responsive—stable parameters and minimal disturbance keep the blue deep rather than washed-out grey.

Green Jaderepresentative

Green Jade

UncommonIntermediate

A relatively recent olive-to-jade green Neocaridina line, harder to fix than reds or blues so color consistency varies. A standout in a green planted aquascape.

Tip: Green is the least stable common color—cull heavily and keep a closed colony, as outcrossing rapidly dilutes the jade tone.

Black Rose / Chocolaterepresentative

Black Rose / Chocolate

UncommonBeginner

Dark Neocaridina lines ranging from deep chocolate-brown to near-black ('Black Rose'). Provides dramatic contrast against light substrate and green plants.

Tip: Display them over pale sand and bright plants so the dark bodies stand out; on dark substrate they visually disappear.

Rilirepresentative

Rili

CommonBeginner

A pattern mutation (available in red, blue and other base colors) where the mid-body is transparent, splitting the color into front and rear bands. Selectively bred from cherry lines.

Tip: Rili patterning is unstable and throws solid and patchy offspring; selectively breed only the cleanest-banded individuals to maintain the look.

Sakurarepresentative

Sakura

CommonBeginner

A mid-tier red grade sitting between low-grade translucent Red Cherry and solid Fire Red: the red is fuller and covers most of the body but the legs and a little of the underside stay clear. The most commonly sold 'good red' Neocaridina.

Tip: Cull the palest and most translucent individuals each generation and keep the colony closed; Sakura readily firms up toward Fire Red grade over a few generations of selection.

Bloody Maryrepresentative

Bloody Mary

UncommonBeginner

A deep, glassy blood-red line bred from the chocolate/wild gene rather than the standard red Sakura line, so the red sits in a clear (not white) shell and looks almost translucent-crimson. A distinct line, not just a high red grade.

Tip: Because the color comes from a clear carapace, Bloody Marys can look washed out under harsh light, so use a dark substrate and subdued lighting; never cross them into Sakura-line reds or you dilute the glassy depth.

Orange Sakura / Pumpkinrepresentative

Orange Sakura / Pumpkin

UncommonBeginner

A bright orange Neocaridina line; 'Pumpkin' tends to a warmer, more opaque orange and 'Orange Sakura' a lighter tangerine. A relatively recent designer color that stands out against green plants.

Tip: Orange is less stable than red, so cull any individuals tinting back toward brown or yellow, and keep them away from red, yellow, and other Neocaridina colors that would interbreed and muddy the line.

Carbon Rilirepresentative

Carbon Rili

UncommonBeginner

A split-color Rili-pattern morph with a dark carbon-black head and tail and a clear transparent midsection, derived from the black/Rili lines. The crisp dark-clear-dark banding is what defines it.

Tip: Rili patterning is genetically loose and throws solid and patchy offspring, so breed only the cleanest dark-clear-dark individuals; display over light substrate so the black blocks contrast with the transparent band.

Snowballrepresentative

Snowball

CommonBeginner

A translucent milky-white Neocaridina named for its bright opaque-white eggs, which look like tiny snowballs under the female's tail. A clean, icy alternative to the colored lines.

Tip: The white is subtle, so a dark substrate and dark background make Snowballs pop; like all Neocaridina, keep them as a single-color colony so offspring don't revert toward wild-type brown.

Red Rilirepresentative

Red Rili

CommonBeginner

The classic Rili: a red head and red tail separated by a clear transparent midsection, selectively bred from cherry lines. The original split-color pattern that the Rili name comes from.

Tip: Selectively breed only the cleanest-banded individuals, as Red Rili throws solid-red and patchy offspring; pairing it with non-Rili reds quickly washes the pattern out of the colony.

Blue Rilirepresentative

Blue Rili

UncommonBeginner

A Rili-pattern line carrying blue rather than red pigment in the head and tail, with the signature clear midsection. Combines the split-color Rili look with the popular blue Neocaridina coloration.

Tip: Blue intensity is stress- and substrate-responsive, so keep parameters steady and use a dark substrate to hold the blue; breed only well-banded individuals to maintain both the blue and the Rili split.

Habitat & enclosure

Cherry shrimp thrive in a stable, mature, well-planted aquarium of at least 19 L (5 gallons), though 38-75 L (10-20 gallons) gives a colony more buffer against parameter swings. They are not demanding about water chemistry but value stability above exact numbers: temperature 18-26 C (65-78 F) with the low-to-mid 20s C ideal, pH 6.5-8.0, GH 4-10, KH 1-8. They tolerate brief excursions toward 28 C but warmer water shortens lifespan, so avoid sustained highs. A sponge filter or pre-filter sponge is strongly recommended so tiny shrimplets are not sucked into the intake. Provide plenty of cover and grazing surface: live plants, Java moss, driftwood, almond (catappa) leaves, and a dark, fine substrate that shows off their color. A fully cycled tank with established biofilm is essential, as cherry shrimp are sensitive to ammonia, nitrite, and especially copper. Acclimate slowly (drip acclimation) and avoid copper-based medications and many plant fertilizers.

Substrate

Dark, inert fine gravel or sand makes colors pop and provides grazing surface; pair with moss, leaf litter, and botanicals that grow biofilm for newborn shrimp. Avoid active/buffering aquasoils unless you intend to manage the lower pH they create.

Equipment & setup

A small cycled tank (5+ gallons) at 65-78F with a sponge filter—essential to avoid sucking in tiny shrimplets and to culture biofilm. Keep parameters stable with moderate hardness (GH ~6-8) for proper molting; zero ammonia/nitrite is critical.

Diet

Cherry shrimp are omnivorous grazers that spend their days picking at biofilm, aufwuchs, and soft algae on every surface of the tank. In a mature planted aquarium they largely feed themselves, but their diet should be supplemented a few times a week with quality shrimp pellets, blanched vegetables (zucchini, spinach, blanched leaves), and occasional protein or biofilm-boosting foods. Feed only what is eaten within a couple of hours to avoid fouling the water, and remove uneaten vegetables. Indian almond leaves and botanicals not only release beneficial tannins but also grow the biofilm shrimp love to graze. Avoid overfeeding, which is the most common cause of water-quality problems in shrimp tanks.

Behavior & temperament

Cherry shrimp are peaceful, social, and best kept in groups of at least 10; larger colonies show more natural foraging and breeding behavior and brighter coloration. They are constantly active grazers and pose no threat to plants, fish, or other invertebrates. Keep them with small, gentle tankmates or species-only, as many fish will eat shrimplets and some will hunt adults. Enrichment comes from a complex environment: moss, leaf litter, driftwood, and dense planting give them grazing surfaces and hiding spots, which is especially important after molting when they are soft and vulnerable. They breed readily in freshwater with no special intervention, so a stable tank quickly becomes a self-sustaining colony.

Health

The leading causes of cherry shrimp loss are water-quality issues and toxic substances. They are extremely sensitive to copper, ammonia, and nitrite, so avoid copper-containing fish medications and fertilizers, and never add shrimp to an uncycled tank. Sudden parameter swings, especially in pH, temperature, or GH, can cause fatal molting problems where the shrimp gets stuck in its old shell (often from insufficient calcium/minerals or a too-rapid water change). Prevention is straightforward: keep water parameters stable, maintain adequate GH/mineral content for healthy molts, perform small consistent water changes with dechlorinated and parameter-matched water, and drip-acclimate new arrivals. Bacterial and fungal infections are uncommon in clean, established tanks. Always vet-review any medication before dosing a shrimp tank. This information is general guidance and not a substitute for advice from a qualified aquatic veterinarian.

Tips, DIY & hacks

They breed readily, so a sponge filter doubles as a shrimplet-safe food source and refuge. Feed sparingly (blanched zucchini, spinach, specialized shrimp foods), use Indian almond leaves for tannins and biofilm, and strictly avoid copper-containing fertilizers and medications.
