I love having shrimp in the tank. My daughter has 4 ghost shrimp in her 10g. They are cheap, .29 cents US at the local pestmart. They just eat whatever falls to the floor. One is actually so tame it will come to the surface and eat flakes from her hand. I have amano shrimp in my planted tank They cost a bit more about $3.00 per shrimp. They are great little guys. They are always on the go either hunting for food or grooming themselves. I say go for it shrimp are a great addition to any tank they are also surprisingly long lived. Ghost shrimp can live to be 10 years old.
