Blue Tiger Shrimp
Caridina cf. cantonensis
The Blue Tiger Shrimp (Caridina cf. cantonensis) is a peaceful shrimp that's a good step up once you have a little experience. Give it a tank of at least 30 litres (8 US gallons), water held at 72-79°F, and a pH of 6-7.5. Always keep a group of at least 6 - they feel safest in numbers.
Captive lifespan reflects typical experience in a home aquarium, not maximum recorded age; genetics, sourcing, and care vary.

Blue Tiger Shrimp Tank Setup
A tank of 30 litres (8 US gallons) or more with rock-steady water suits them best - keep it at 72-79°F with a pH around 6-7.5. Stable conditions matter most, as shrimp struggle to moult and breed when parameters bounce around. Always keep a group of at least 6 of their own kind - kept alone or in pairs they tend to turn shy, nippy, or wash out in colour.
What Do Blue Tiger Shrimp Eat?
They're grazers, so base their diet on algae, blanched vegetables, and spirulina-based foods rather than high-protein flake. A spotless tank with nothing to graze on leaves them thin and underfed.
Blue Tiger Shrimp Tank Mates
Blue morph of Tiger Shrimp. Slightly more tolerant than Taiwan Bee variants. Avoid copper medications. The Blue Tiger Shrimp is peaceful, which is the first thing to weigh up when you choose tank mates. It's a shoaling fish, so settle a group of 6 or more of its own kind before adding anything else - a stressed, lonely fish is far more likely to nip or hide. Before you buy, run your full stocking list through our stocking calculator. It weighs temperament, adult size, and water needs together, which a single species page can't do on its own.
Are Blue Tiger Shrimp Good for Beginners?
Doable once you test water regularly and catch problems before fish look sick. If this is your first tank, pick something more forgiving and come back later.
