Salt water fish have become increasingly popular. This is probably due to recent technical developments which have brought the keeping of coral fish within the price range and caretaking ability of the average fish owner. Fish have always been very popular as pets since they don't take up much room in a small apartment, they don't need to be walked or trained, and they are relatively easy to care for.
