And that's exactly why I have started this thread, a whole lot of information out there, none it scientific based and quite possibly wrong.
So I am looking to get some feedback from people who have kept them, what salinity levels and how their fish behaved.
I currently have mine up to about 1.20 and am going to take him to full marine and hold him there for a while. I haven't seen a black or grey belly since about 1.15, on a species that numerious people claim that black bellies on this puffer are the norm. Well all those people could just be wrong and been keeping their fish at the wrong water parameters. It simply doesn't make sense when a black belly is a sign of distress on all puffers, except the saba. That plus the fish has not behaved as vibrantly as he is now, as compared to the lower salinities.
I know that oddball kept a group of them at 1.08 to 1.15 over a period of four years and kind of took my lead from him.
