Here is my brackish tank. It’s a 26 gal bowfront, black sand, coral rock, and some fake plants/roots. Salinity is 1.005, so lower end of the scale. Inhabitants are 2 figure 8 puffers, a knight goby, 2 orange chromides (cichlids), and 4 random mollies. I have an overload of water sprite in another tank so threw one in the brackish to see how it does. The puffers chew on any Anubias or Java fern🙁. The mono sebae (triangular fish) is in qt right now and will go in the main tank in a couple weeks.
