While waiting for Carol at the heart doctor's office, I had time to watch the fish tank activity. The busiest fish was a cleaner fish. I don't know the name of this fish, but it sure was an interesting one! It sure has the mouth for the job. Looks something like a vacuum cleaner. :)

I found out that the fish is a "Hypostomus plecostomus", called by some the 'suckermouth catfish'. Press here for Link
