Saltwater fish are found in all of the three basic types of saltwater aquariums: Fish Only saltwater aquariums (FO), Fish Only with Live Rock saltwater aquariums (ROWLR) and Reef Aquariums. Keeping fish in saltwater aquariums didn’t become popular until the 1950s, even though a handful of scientists and saltwater enthusiasts attempted to keep saltwater species earlier.
One of the main advantages of a saltwater aquarium is that you will be able to keep a vide range of extraordinary beautiful fishes that can not be kept in freshwater aquariums. Examples of popular saltwater fish are Damsels, Lionfish, Clownfish, Triggerfish, Blennies, Butterfly fish and marine Angelfish. When you set up your first saltwater aquarium it is advisable to begin with some of the sturdier marine fish species. Damsels are good beginner fishes since they are tougher than many other marine fish species. They are also comparatively inexpensive. Damsels are frequently used as cycling fish by experienced saltwater aquarists when setting up a new aquarium. You should however keep in mind that Damsel fish are quite aggressive and unsuitable tank mates for a wide range of other saltwater species.
