Overview
The tiger shrimp is a peaceful Caridina for a cool, planted freshwater tank. It is best with a little experience.
Did you know
Tiger shrimp readily crossbreed with other Caridina of the same species group, like crystal and bee shrimp. That is how many mixed-up patterns end up in the hobby.
Caring for the tiger shrimp
Keep tiger shrimp in a group in a tank of 7 gal (25 L) or more, since shrimp are more confident and active in numbers. Set up a mature, planted tank with moss, fine cover and good filtration. They live on the bottom and over plants, grazing all day.
Tiger shrimp need cool water, below typical tropical temperatures, at 64 to 73°F (18 to 23°C). That often means a tank in a cool room or one with no heater. Keep the water soft to neutral at a pH of 6.0 to 7.5, with no copper and no big swings.
Feed biofilm, algae, blanched vegetables and the occasional shrimp pellet. They are peaceful, so house them only with small, gentle fish or other shrimp that will not eat them.
Tiger shrimp breed in fresh water without a larval saltwater stage. Females carry the eggs under the tail and release fully formed miniature shrimp. To keep a clean line, do not house them with related shrimp, since the offspring blend together over generations.
Good to know
The tiger shrimp, Caridina mariae, is a dwarf freshwater shrimp in the family Atyidae. It carries dark, tiger-like banding and often orange eyes.
In the wild
The tiger shrimp comes from southern China and Hong Kong. It lives in cool, clean, well-oxygenated streams with stable water.

What temperature and pH does a tiger shrimp need?
A tiger shrimp is comfortable at 64–73°F (18–23°C) with a pH of 6.0–7.5.
What does a tiger shrimp eat?
A tiger shrimp grazes on biofilm and algae all day. Add blanched vegetables and the occasional shrimp pellet.
How big does a tiger shrimp get?
An adult tiger shrimp reaches about 1.6 in (4 cm).
How does a tiger shrimp breed?
A female tiger shrimp carries her eggs under the tail and releases fully formed miniature shrimp. There is no larval saltwater stage, so tiger shrimp breed in fresh water.
