Ghost shrimp will eat any kind of fish
food that reaches the bottom, making them excellent scavengers. They
also will eat algae. They are peacefull, but some larger fish might
try to eat the shrimp, or harass them. As long as the water is clean
they will just about take care of themselves, and if you're lucky they
might produce some eggs for you. Shrimp that are carrying eggs are easy
to spot, the eggs are yellowish to green and carried beneath the females
swimmerets (legs) until they are developed enough to fend for themselves.
