got a 2" fahaka today and seems very healthy other than a white ball on one side of his gills, looks like a tiny piece of styrofoam(you know what i mean, its not really styrofoam). tank is at 79f and i added 4 tbls. of salt(40g growout tank). i was wondering if i could add seachem paraguard or if this was bad for the puffer? it looks like i could pull the thing off with tweezers but i dont want to harm him, one slip and i could really hurt him.
