A long, long time ago, my parents got a saltwater fish tank. They had a little peppermint shrimp that they loved, but soon after they got it, one of the fish in the tank ate their poor peppermint shrimp. My parents were devastated and haven't had a fish tank since.
So, I want to get them a peppermint shrimp that is protected against fish. Most likely, that will mean it will have its own little happy tank/bowl.
