You may have been complimented from time to time on your aquarium, probably more for sunken treasure chest next to the undersea castle, the model of the old-fashioned deep-sea diver with the brass helmet, and most especially for the pretty pebbles at the bottom of the display. Your friends probably don't even know what type of fish you have inside, and wouldn't know the difference between a tiger barb and a tinfoil barb unless there was a map on the outside of the aquarium.
