These are freshwater Shrimp that are incredibly peaceful and renowned for their algae eating capabilities.
Suitable for both beginners and experienced aquarists as they are very undemanding requiring very little upkeep.
If you watch them you will see that they spend large periods of their day grazing on whatever is in your aquarium; plants, moss, substrate etc.
They are very active throughout the day and night.
The water in the tank must be stabilized before the shrimp is placed in the tank. When they arrive, they will be a little stressed from the shipping and will look white/clear. Give them some time to settle in and color up.
