Tropical Marine Fish are all sorts of shapes and sizes. As such, they cost a lot more money to install than a similar sized freshwater aquarium. Tropical marine aquariums also require much more maintenance to keep them happy and healthy.
We prefer to visit reef aquariums weekly to ensure we keep an eye on everything, and keep on top of all the maintenance tasks. The fish can be a lot more random in their behaviour — and even fish that are supposed to calm and friendly can differ from the normal!
A lot of the fish are caught from the wild and imported, therefore they have a massive transition to get through to get to your tank. As such, there is a bigger risk of losing the fish to stress when keeping marine fish, as this transition can take months. Marine fish in larger reef tanks can be difficult to treat for disease, as many remedies cannot be used with corals.
In this situation, the fish have to be removed from the reef tank for treatment, which in a larger tank can be nigh on impossible!! Feeding marine fish can often be more specialised, involving frozen foods which cannot be automatically fed. This requires more intervention than would be required with a tropical freshwater tank.

Brackish water fish tend to be opportunistic in nature. Provide a varied diet, but always research the dietary needs of any fish you purchase. Archerfish and datnoids can be finicky at first, but once weaned off live foods, they will thrive on Aqueon Monster Fish Medley. Puffers should be fed live snails on occasion to help file their constantly growing teeth.
On the surface, the differences between freshwater fish and saltwater fish are obvious: one lives in saltwater and the other lives in freshwater. Saltwater typically refers to water found in oceans and seas, and freshwater is found in lakes, rivers, ponds, and streams.
Freshwater only accounts for less than 3 percent of all the water on earth, but ironically, freshwater fish make up almost half of all fish species. Gourami fish are among the more popular fish for freshwater aquariums. The way fish take in and eliminate water is perhaps the most significant difference between saltwater and freshwater fish. Both types of fish need salt in order to survive, but the way their bodies function is actually the opposite of what one may expect.
