Orange Shrimp Care Guide - Aquarium Setup, Feeding & Breeding

Orange Shrimp are a bright, selectively bred variety of the small freshwater shrimp Neocaridina davidi. Their bodies range from translucent orange to a rich, opaque pumpkin shade, with colour intensity varying between individuals and breeding lines. Females are typically larger and more strongly coloured than males.

These peaceful dwarf shrimp spend much of their time grazing on algae, soft biofilm and microscopic organisms from plant leaves, wood, stones and other surfaces. They are active during the day as well as at night, although they can become less visible when housed with boisterous or predatory fish.

Like other Neocaridina, Orange Shrimp periodically moult their exoskeletons as they grow. After moulting they are temporarily vulnerable, and a discarded shell may be eaten as a useful source of minerals. Their short life cycle and prolific breeding make them fascinating inhabitants for a planted freshwater aquarium.

In the aquarium trade, Orange Shrimp are maintained through selective breeding for different shades and levels of colour coverage. Their appearance can vary with genetics, age, background, diet and stress, and offspring from mixed Neocaridina colour varieties may develop less predictable colours.

Orange Shrimp are a selectively bred colour form of Neocaridina davidi, a species native to freshwater streams, pools and rivers in Taiwan and parts of mainland East Asia. The orange colour does not represent a separate wild species.

A group of Orange Shrimp can be kept in an established aquarium of around 20 litres, with a larger tank providing greater stability and room for a growing colony. A footprint of approximately 30 × 30 cm is a useful minimum guideline, although longer aquariums offer more grazing area. Use a gentle or shrimp-safe filter, and provide live plants, moss, driftwood, stones, leaf litter and other surfaces for biofilm to develop. A dark substrate can enhance their colour, while fine gravel or sand is suitable; avoid copper-based treatments and sudden changes in water chemistry.

Females reach up to about 3 cm (1.2 inches), while males are usually smaller at around 2–2.5 cm (0.8–1 inch).

Orange Shrimp graze naturally on algae, aufwuchs, biofilm and decomposing plant matter. Supplement this with a quality shrimp food containing appropriate minerals, along with small portions of blanched spinach, courgette, cucumber or other suitable vegetables. Occasional foods containing protein can support growth and breeding, but overfeeding quickly pollutes the water. As they moult, access to calcium and other minerals is important for healthy exoskeleton development.

Orange Shrimp are best kept with other peaceful invertebrates and small, gentle fish such as ember tetras, celestial pearl danios, small rasboras, otocinclus and pygmy corydoras. Snails including nerites and ramshorn snails are generally suitable companions. Avoid large, aggressive or predatory fish, including bettas with a strong hunting instinct, gouramis, cichlids, many loaches and larger barbs, as they may eat adult shrimp or their young. Even peaceful fish can consume newly hatched shrimp.

Orange Shrimp breed readily in a mature freshwater aquarium when well fed and kept in stable conditions. Females carry a clutch of eggs beneath the abdomen, where the eggs are fertilised and fanned until they hatch after roughly three to four weeks. The young emerge as fully formed miniature shrimp and need fine foods, biofilm and protection from fish that may eat them. No separate larval brackish-water stage is required.

Females are generally larger, broader-bodied and more intensely coloured than males, with a curved abdomen for carrying eggs. Males tend to be smaller and slimmer, often with more translucent colour; mature females may also show an egg-shaped saddle behind the head before spawning.
