Gaining a little experience with a freshwater system is a great way to prepare
yourself to enter the marine side. A beginner can maintain a successful
marine tank, but the lessons you learn are expensive. We see many new hobbyists
become disheartened because they start out with a marine setup
that’s too much to handle. If you have a friend experienced in marine systems,
ask her for advice — she may be able to get you started successfully.
Many marine fish are social time bombs waiting to explode all over the other
fish in your tank. In fact, saltwater fish can be down right rude. Most community
freshwater fish have reached a state of enlightenment or something like
that, and are pretty cool with each other.

Invertebrates are animals that have no backbone. They are animals even
though many of them look like plants of some sort. Invertebrates make saltwater
aquariums look very cool. Invertebrates make up a surprisingly large
number of the total animal population. About 2 million species of animals
inhabit the earth, and roughly 97 percent of them are invertebrates.
