Hi, I have never had a saltwater tank and am looking to set up a small tank to start. It is for my son, so i wanted to start out small. I do have a 60 gal freshwater tank so i do know the maintenance required. I have a 10 gal tank and canopy, but am not sure what else i may need. If anyone has any suggestions I would highly appreciate it. And yes I am aware hat it is only feasible to have one small fish in a tank so small.
