Neocaridina Shrimp — The Complete Feeding Guide
Neocaridina shrimp are a versatile live food and aquaculture organism, valued for their hardiness, nutritional density and suitability across a wide range of predator and community setups. This guide covers everything from biology to feeding applications.
What Are Neocaridina Shrimp?
Neocaridina davidi is a small freshwater shrimp species widely kept in the aquarium hobby, both as ornamental livestock and as a live feed organism. At Jack's Aquatics, our Neocaridina shrimp are bred in-house in UK mineral-supported systems — never imported, never wild caught.
As a decapod crustacean, Neocaridina shrimp fall under a different legal classification to our snail and culture range. They are recognised under the Animal Sentience Act 2022 as falling within the definition of "animal" — and we treat them with the same welfare standards we apply across our entire operation, dispatched exclusively via Royal Mail Special Delivery to ensure safe live arrival.
ClassificationNeocaridina davidi is a decapod crustacean. Under the Animal Sentience Act 2022 (England and Wales), decapod crustaceans are recognised within the legal definition of "animal" — reflected in our enhanced dispatch standards for this species.

Why Neocaridina Shrimp Work So Well
Nutritional Value
Shrimp are a dense source of protein and essential fatty acids, making them a valuable addition to a varied feeding programme. Their exoskeleton also provides a natural source of chitin and calcium — beneficial for predators that consume shells as part of their diet.
Movement and Behaviour
Unlike snails, Neocaridina shrimp are fast, erratic swimmers. This movement pattern is highly stimulating for predatory fish that hunt by sight and motion — triggering chase and capture behaviours that static or slow moving foods simply cannot replicate.
Key PointThe combination of high nutritional density, natural movement and shell content makes Neocaridina shrimp one of the most complete single feed items available — particularly valuable for predators that benefit from active hunting enrichment.
Which Setups Benefit Most
Larger Puffer Fish
Species that have outgrown snails as a primary feeder benefit from the larger, faster moving prey that shrimp provide — a natural progression in a varied feeding programme.
Cichlids
Many cichlid species actively hunt small crustaceans in the wild. Live shrimp provide an enrichment feed that closely mirrors natural prey items.
Larger Loaches
Bigger loach species that have moved beyond snail-only diets take readily to live shrimp as part of a rotation feeding approach.
Freshwater Crabs
Omnivorous freshwater crab species will actively hunt and consume small shrimp, providing both nutrition and natural foraging behaviour.
Established Shrimp Keepers
Hobbyists building or supplementing their own Neocaridina colonies benefit from fresh genetic stock to maintain colour lines and colony vigour.
Turtles & Terrapins
Live shrimp provide excellent enrichment and a calcium-rich food source supporting healthy shell development in semi-aquatic reptiles.
Introducing Shrimp to Your Tank
Acclimation
Neocaridina shrimp are more sensitive to sudden parameter changes than snails. We recommend a slower acclimation process — float the bag for 15-20 minutes for temperature equalisation, then gradually introduce small amounts of your tank water into the bag over 20-30 minutes before release. This is particularly important for shrimp destined for breeding colonies rather than immediate feeding.
ImportantIf shrimp are intended for immediate feeding to predators, rapid introduction is generally not a welfare concern given the short timeframe involved. For shrimp intended to establish or join a breeding colony, a more gradual acclimation reduces stress and improves settling success.
Water Parameters
| Parameter | Range | Notes |
|---|---|---|
| Temperature | 18-28°C | Stable temperature reduces stress |
| pH | 6.5-8.0 | Prefers 7.0-7.5 |
| GH | 6-8 | Important for healthy moulting |
| Ammonia/Nitrite | Zero | Shrimp are highly sensitive to spikes |
| Copper | None | Toxic to all crustaceans — check medications and fertilisers |
CriticalCopper is highly toxic to shrimp even in trace amounts. Many fish medications and some plant fertilisers contain copper. Always check before treating a tank that contains shrimp.
Feeding Frequency for Predator Tanks
| Predator Type | Recommended Frequency | Notes |
|---|---|---|
| Larger Puffers | 2-3x per week | Alongside snails for variety |
| Cichlids | 1-2x per week | As part of varied diet |
| Larger Loaches | 1-2x per week | Supplement to snail diet |
| Freshwater Crabs | 2-3x per week | Natural foraging behaviour |
Why Buy From Jack's Aquatics?
Shrimp quality and genetic diversity directly affects both feeding outcomes and breeding success for keepers building their own colonies. Stressed or poorly conditioned shrimp from overcrowded systems carry reduced nutritional value and are more prone to dying in transit.

Important Context & Expectations
Feeding outcomes vary between individual fish and setups. Not all predators will immediately accept live shrimp — introduce gradually and observe. For shrimp intended for breeding colonies, water parameter matching with your existing setup improves settling success.
All livestock supplied by Jack's Aquatics is dispatched in good health. Post-delivery outcomes depend on tank conditions and keeper management. For full delivery and claims terms refer to our Terms & Conditions.
