However, a saltwater tank requires more maintenance costs as they include reef systems, refugium and advanced filtrations systems more than the freshwater tanks.

Setup costs: Now let’s talk about the setup costs for both the freshwater aquariums and saltwater aquariums. To keep things simple, you can start looking up for fish only systems apart from the reef tanks. However, a best freshwater aquarium needs some essential equipment which can be optimized when compared to the additional amount that is to be spent for modern filtration systems and additional components of a saltwater aquarium. Talking about which, a saltwater aquarium might need some test kits to keep the ecosystem clean and functional, and also you need to invest in getting a good skimmer for live rock for biological advantages.

The periodical changes are different for different water, and it is said that the freshwater aquarists can remove some water from the tank and refill it with filtered water to ensure the quality of water with the help of an aquarium vacuum. On the other hand, the saltwater tanks can’t be cleaned in this way, and they will need a separate container to drain the old water and refill the new water to make a water exchange.

Fish costs: Saltwater fish are relatively expensive than the fish of freshwater. Also, you can’t find the saltwater fish stores just anywhere in the town and when you find one your jaw drops because of the prices as well as the number of species that you can find.

However, there are a set of species like the Dwarf Angelfish, Clownfish which are being farm raised these days and if you think that price is not an issue in this case, you can try buying these fish. One more thing to know about the saltwater species is that they can carry many external diseases and parasites as they come from the wildlife.

Invertebrates: The amounts of invertebrates that are available to place in the saltwater tank are unlimited. However, freshwater invertebrates are limited and regular but are locally available. You can try placing different shrimps, clams, corals, sea stars, worms, feather dusters in the saltwater tank and create a lively aquarium at your place.

Fish colors: Finally, the fish colors of saltwater species are exceptional, and they create a breathtaking view as a part of your interior.
