i have figure 8 puff keeping with a green spotted puffer and a acherg fish, i have added salt to the tank and the specific gravity is about 1.010 rite now. my question is ar they pure fresh or brakish water fish? can i change the system to full marine cuz i might get some yellow mono later. i know the gsp can be in the full marine but dun know about the figure 8 can be in the full marine system or not.
thanks
