It would seem that, that hypothesis is the case as since the storm passed my fish are back to thier normal selves as of today. They are eating a lot and are all out and about swimming and grazing as if nothing happened today. I currently have 8 tangs in my system and all 8 and the fox face did the same thing during the storm in which your storm theory was about. They all went to the deepest part in my tank and hid under the rocks for the duration of the storm until today. They started acting strange on monday and weren't as food motivated and just seemed to want to hide in thier caves more. And it only got worse as the time progressed to the point where they would only take a small piece of food and that was it basically for all day. They weren't grazing or anything. They just wanted to hide at the deepest part of the tank and camo up. Like it is when I go and shut off the lighting at night time. Now they are all schooling like normal and are doing great.
