also.. he is living in freshwater, i believe the cause for the black belly, in a 10 gallon tank. (i'm trying to convince my mom into letting me get a bigger one) I bought some instant ocean and a hydrometer but i don't know how to go about converting my freshwater tank to brackish water with the puffer in it, or how much salinity there should be. any help is greatly appreciated.
