Okay so, I just started a 30 gallon tank with the plan of only adding puffers in. Last Friday, I added in 2 Figure 8s, Saturday, added in another figure 8, and today, added in a Green Spotted. Went and had the water tested and everything was good except the PH was a little low. Right now, they are in Freshwater but, within the next week, I'm going to start acclimating them to the brackish water which I assume will raise the PH. Any tips and suggestions would be greatly appreciated.
