I just learned what a brackish tank is. I have what I thought was a freshwater tank, but I add aquarium salt to it, so does that mean it's a brackish tank? How much salt needs to be added for it to be considered brackish?
Also, I searched for a list of brackish fish and realized that some of the fish in my tank are considered brackish. Is it ok to have them in the same tank as freshwater or will some of them be unhealthy because they do not have the correct level of salt in the water?
I've had my 10g tank for about 8 months. 2 fiddler crabs, 1 guppy, 1 balloon molly, 1 tiger barb, and 1 fish that I don't know the name of. I'm posting another thread with a picture of it, I'm curious what it is, I don't recall what it said at the fish store.
Any advice will help, thanks in advance!!
