I have read that watching fish in an aquarium can lower blood pressure. Maybe it is so. But I also have to wonder about those little guys. What do they think as they swim around and around, back and forth. Do they communicate with each other? I know they all seem to fight for a spot at the top when it is feeding time. They seem to enjoy chasing each other around. The mollies like to chase each other around. The zebras and tetras like to swim around together. The red tipped shark likes to hide in the cubby holes of the rock. Then there is the fish that likes to clean the glass and rocks. What a job. Who caught all those fish? After watching them race around, up and down and across, I wonder. What do they do for fun? I would think it would get boring quickly. Just imagine going around and around all day getting nothing done. Sounds like some jobs I have had. Seems a little boring to me. But then again I am not a fish.
