I'm sorry if i'm not posting this under the right area! I didn't know where exactly this question would fall. But I currently have two tanks running, a 30 gallon brackish tank and a 70 gallon saltwater tank. My 30 gallon tank WAS intended for my green spotted puffer, but I had adopted my green spotted from a home where he was neglected and unfortunately he only made it a month before passing. 
Anyways, In addition to the puffer, I also had a very small, 2 inch flounder in my brackish tank. Now, I don't plan on getting another puffer, but I really do like my flounder. If I could somehow eventually get my flounder into my marine tank that would really be convenient rather than having a 30 gallon brackish tank I don't necessarily want just because I like one tiny fish in there.
I honestly don't know what kind of flounder he is, I asked questions at the shop when I got him and they weren't much help other than agreeing with me that he was a brackish fish. His label at the store was simply "flounder" and he was only 4.99, in a tank with some bumblee gobies.
Here are some pictures. Is he a type that could eventually be acclimated to saltwater? Or do you think it is unsafe?
I really would prefer to use my 30 gallon for a freshwater tank and move the one fish I like in there out and into my saltwater, but if it can't be done I assume I'll keep the tank and maybe put some gobies in it, even though all i really want it for is the flounder.
Salinity in my brackish right now is 1.008, Salinity in my saltwater is 1.026.
