Red cherry shrimp respond to the colour of their background and substrate. If they are kept in a tank with light-coloured substrate, they will become paler, or even transparent. On a darker substrate, they take on their full red colouration. Colour intensity also depends on the types of food available (live foods and those high in protein and fats are more beneficial than flake foods), water pH, and temperature. Prepared foods specifically designed for shrimp are available at some suppliers.
