  • The goal of each serious aquarium keeper is more than simply to display some pretty fish. The serious aquarium keeper hopes to create a little environment to present some of nature's most special and spectacular creatures, fresh and brackish water tropical fish. Unfortunately, many species of fish are endangered or on the brink of extinction because of mankind. The destruction of rainforests, the damming of rivers, the polluting of rivers, and the introduction of non-native species are acts which most directly affect tropical fish.
