There are aquariums for saltwater fish and for freshwater fish, and the requirements for each are vastly different. Many people prefer salt water fish, though, because they are more colorful and there is a huge range of plants and invertebrates that are available to accompany them. A salt water fish aquarium may be harder to care for, but with a striking variety of reef fish and other tropical life forms to select from it is well worth the extra time, money and effort. The first step to having a functioning salt water fish aquarium is buying the aquarium itself, which is one of the toughest decisions to make. Depending on how many salt water fish you plan on having, the process of choosing may require more time and be confusing, as the range is very large for the available tanks.
Since you don't know how many saltwater fish you will end up adding to your collection down the line, the best bet is generally to acquire the biggest tank within one's budget. A larger salt water fish aquarium can always be adjusted to accommodate the new fish. A 35 gallon salt water fish aquarium is most likely the smallest fish tank that a new hobbyist should be considering. In order for the salt water fish to thrive, it's necessary to have enough surface area to allow for adequate replacement of oxygen in the water and even to provide a relaxed swimming atmosphere for the fish. Having successful saltwater fish requires a proper supply of oxygen and water temperature of approximately 76 degrees F. Aeration can generally be supplied in conjunction through the filtration device. Hobbyists can also choose their salt water fish aquarium in either glass or acrylic, although many people prefer the glass variety because of the way it looks. After choosing the right one, it just needs to be installed in the desired location with all the chemicals and other essentials, and it's ready for fish.
