Shrimp are small aquatic creatures. They need a gallon tank. Do not put them with fish that are carnivores. The Ghost Shrimp may live up to a year. They eat the same thing fish eat and clean the tank like snails. Shrimp might be hard to find when you want to look at them. They can easily blend in with their surroundings. They will clean the tank by eating bacteria. But you still have to change the water. They can be interesting to watch. If you enjoy watching fish, you will enjoy watching shrimp.
