Poecilia velifera (Sailfin / Yucatan Molly) - beautiful fish for big tanks and *brackish* waters.
Brackish tanks are a good way to explore the salty side of the hobby without setting up a marine or reef tank. Unlike true saltwater systems, brackish aquariums do not require the considerable cost, complexity and time commitment required to be successful – but they still offer something definitely different than freshwater. Some of the most interesting fish in the hobby are brackish species, and the aquarist of today has many brackish choices.
For the aquarist with limited space, a low salinityaquarium, planted or otherwise, is a worthwhile option. A typical lowsalinity brackish water environment would be a coastal stream thickwith plants, where the influence of the sea is only very slight. Thereare many small brackish water fishes, in particular gobies,livebearers, killifish, glassfish, halfbeaks, pufferfish, and dwarfcichlids that would work well in an aquarium based around thisenvironment. Some of these will do well even in tanks as small as 10gallons. A low salinity aquarium should be maintained at SG1.003-1.005, the exact salinity depending on which fish and plantsbeing kept.

how much salt equals brackish water? - Fish Tank
Brackish Water Fish are species of marine life that are able to survive in slightly salted water. A brackish tank system is defined by water with a specific ratio of fresh water to saltwater, referred to as “gravity” where the water maintains a fresh water level of 1 and a saltwater level of 1.025. There are numerous dynamics to consider when maintaining a brackish aquarium, even beyond the live fish you are keeping, one must also be mindful of the interactions of your plant life, equipment, and other general maintenance duties that require patience and an eye for detail.Overall, the brackish water environment shares many of the same species and characteristics as a standard fresh water tank. The challenge to the aquarist is to select the appropriate mix of plant life and livestock to represent a natural habitat that can live harmoniously. In addition, a close eye for salinity levels and regular maintenance are key to a successful brackish water fish environment. Careful selection of your plant life and fish will enable you to create a truly beautiful and unique aquascape that is an accurate and realistic representation of their habitat.Brackish water aquariums and their fish require a delicate balance of freshwater and saltwater in their environment. It is common that Brackish water species be kept mainly in the same standard freshwater tank; however, a tool called a hydrometer is used to check the salt levels of the water. Specific fish do require changes to the overall salinity of the water after a specific amount of time. For example, after 6 months in a specific aquarium, there may need to be an increase in salinity for the fish to continue to survive.This bottom dweller is already a brackish water fish so there's no need for a lengthy acclimation process. The Bumble Bee Goby likes to dwell in the lower regions of the tank in groups.
