Amano Shrimp Care Guide
Caridina multidentata
Key Takeaways
- Amano Shrimp needs at least 10 gallons, with 20 gallons preferred.
- Keep water between 20-26°C and pH 6.5-7.5.
- Keep a group of at least 3 to reduce stress.
Actionable Setup Plan
- Use a mature, planted 10+ gallon tank with grazing surfaces, a lid, and gentle intake protection.
- Supplement algae with algae wafers or blanched vegetables; a spotless aquarium may not provide enough food.
- Keep copper-containing medicines out of shrimp setups and allow stable minerals for moulting.
Quick Facts
Size
Amano shrimp grow to about 5 cm (2 in), which makes adults less vulnerable than cherry shrimp but not safe from every predator.
Lifespan
They commonly live 2-3 years in stable freshwater; their larvae do not develop into adults in a normal freshwater tank.
Minimum School Size
Keep a small group of at least 3 when the aquarium has enough food and cover.
Care Overview
Amano shrimp are considered the best algae-eating shrimp for freshwater aquariums. They are larger than cherry shrimp and very effective at controlling algae.
Ideal Tank Setup
A 10+ gallon planted tank with lots of surfaces to graze on. They need a lid as they can escape. A sponge filter is recommended.
Food
Primarily algae eaters, but supplement with algae wafers and blanched vegetables. They need a constant food source.
Tank Mates
- Small tetras
- Corydoras
- Cherry shrimp
- Snails
Fish to Avoid
- Large fish that may eat them
- Aggressive species
Common Problems
- Escaping from uncovered tanks
- Starving in clean tanks with no algae
Common Beginner Mistakes
- Using a tank smaller than 10 gallons, which makes water quality harder to keep stable.
- Ignoring adult size, group size, or temperament when choosing tank mates.
- Changing too much water or filter media at once before checking ammonia and nitrite.

Larger shrimp can be less vulnerable, but an individual betta may still chase or attack them.
Shrimp are sensitive to sudden water-quality changes; test and correct problems gradually.
Compatibility verdict: possible (65/100).
Compatibility verdict: good (95/100).
Algae growth is normal but excessive algae indicates an imbalance of light, nutrients, or CO2.
