Saltwater fish aquarium can be found in most places like homes, restaurants, showrooms, malls, hotels, etc. If you are a hobbyist and would like to have one for yourself then consider setting one for the three different types of aquariums which are discussed below.

Types of Aquarium:

Fish Only Aquarium: This type of aquarium is suitable for beginners as it is inexpensive, easy to install but requires lots of maintenance. This tank requires a water test kit to periodically monitor the ammonia, nitrite, nitrate and pH levels. As the name suggests this aquarium is only meant to keep fish but you can add snails or hermit crabs to help control any algae problems. This type of tank can be further divided into community tank and semi-aggressive tank. The community tanks house species that will get along well with the other species in the tank. Semi-aggressive tanks usually house solitary individuals from different species.

Aquarium with Fish & Live Rock: This tank is similar to the above tank but with added live rocks and better decorations inside. The reason for keeping live rocks in a tank is they are the best form of natural biological filtration for the saltwater aquarium. When rock is put inside an aquarium organisms and algae start growing on it which in turn becomes food for the invertebrates and fish. You have to get an experts advice in order to put live rock in your aquarium. Also note that live rocks are an expensive commodity and putting one in you tank is the most expensive part of setting up a tank.

Reef Tank: Reef tanks are the most experience to set-up and are usually done by highly experienced hobbyists. The reason for that is this tank requires excellent water conditions, extremely high lighting levels (expensive), water supplements, reverse osmosis and/or de-ionized water (expensive), and excellent filtration (usually live rock). Fish are rarely found in these tanks as the motive of reef keepers is to keep their corals and anemones growing. These invertebrates, corals and anemones can be very expensive and very hard to keep.
