Cherry Shrimp
Neocaridina davidi
Cherry Shrimp graze biofilm off every surface all day, and shift tone with the substrate and their own condition. The wild animal is a translucent brown; every vivid colour in a tank is something people selected for, not something the shrimp chose.

Introduction to Cherry Shrimp
Cherry Shrimp graze biofilm off every surface all day, and shift tone with the substrate and their own condition. The wild animal is a translucent brown; every vivid colour in a tank is something people selected for, not something the shrimp chose.
How to identify a Cherry Shrimp
- Small shrimp, 2.5-4 cm, females larger and more strongly coloured
- Constantly picking at surfaces with paired feeding claws
- Translucent brown in the wild; red and other morphs are bred
- A saddle of developing eggs visible behind the head in females
Why Cherry Shrimp are interesting
- The wild form is a mottled translucent brown. Fire red, blue and yellow morphs are all products of selective breeding in the aquarium trade.
- Chromatophores let an individual darken or pale over hours to match a substrate, but they cannot produce the bred colours to order.
- Neocaridina davidi breeds entirely in fresh water with no marine larval stage, which is why it establishes so easily in tanks and, where released, in the wild.
- A female carries 20-30 eggs under her tail for about a month, fanning them constantly with her swimmerets.
- Native to eastern China and Taiwan, and now feral in several warm-water systems worldwide.

Why does Cherry Shrimp behave this way?
- Small shrimp, 2.5-4 cm, females larger and more strongly coloured
- Constantly picking at surfaces with paired feeding claws
- Translucent brown in the wild; red and other morphs are bred
- A saddle of developing eggs visible behind the head in females
Grazes on and off around the clock with no true rest, though activity dips in the brightest part of the day and rises at dawn and dusk.

Why Native range keys: east_asia. Shallow streams and ponds with dense vegetation?
Habitat: Native range keys: east_asia. Shallow streams and ponds with dense vegetation, leaf litter and steady flow over rock. Cluttered, well-planted water suits an animal whose whole strategy is to keep grazing without being noticed.

05
Why this diet?
Biofilm, algae, decaying leaves and detritus, grazed continuously from every available surface. It is unselective, low-value food available everywhere, which is exactly what makes constant quiet work viable.
06
Activity, rest, and lifespan
Grazes on and off around the clock with no true rest, though activity dips in the brightest part of the day and rises at dawn and dusk.
One to two years, with females reaching breeding size at around four to five months.
07
Cherry Shrimp reproduction
Females carry the eggs under the abdomen until they hatch as fully formed miniature shrimp. There is no larval stage at all, so young start grazing the same surfaces the adults do immediately.
Females are larger, deeper-bodied and more strongly coloured, with a curved underside to the abdomen for holding eggs. Males are smaller, slimmer and paler.

Where to find them
Where to find Cherry Shrimp
To find Cherry Shrimp in the wild, focus on the exact habitat patches that match its body design and daily behavior, not just the broad country where it exists. You usually do better by working one good piece of habitat inside native range keys: east_asia. Shallow streams and ponds with dense vegetation, leaf litter and steady flow over rock. Cluttered, well-planted water suits an animal whose whole strategy is to keep grazing without being noticed. than by covering too much ground.
- Quiet marsh edges, reedbeds, river bends, or shallow wetland margins
- Headlands, reef edges, island colonies, tidal channels, or productive coastal water
- Protected habitat blocks within native range keys: east_asia. Shallow streams and ponds with dense vegetation, leaf litter and steady flow over rock. Cluttered, well-planted water suits an animal whose whole strategy is to keep grazing without being noticed.
