So Benny here decided that he wanted to be even lazier than he had been. I'm not sure if he was depressed or stressed, but he wasn't flaring for the mirror I put next to the tank. I went to Petco (only closeby store for fishies) and explained my situation, someone in the fish department told me to try Betta Revive and see if it helped, and to check forums, because people have probably encountered something similar before (I already had been searching before, but spent some more time after looking). I tried the Revive last night and figured I'd see what happened in the morning. When I awoke this morning I find that he is seriously bloated, and keeping himself from rising by staying under the filter or grass. I fear it might have been the Revive to cause it but I'm unsure. After going through those helpful stickies, I thought it may be dropsy, sbd, or maybe constipation. His eyes were not swollen nor were his scales popping out. I ruled out dropsy with that. When I preformed a 100% water change this afternoon (put him in a little bowl) and washed the tank and stones and plants, I saw him poop in the small bowl, so I ruled out constipation.
The data below is from after the 100% water change. Before hand when the symtoms first started to appear the pH was ~7 and the temp was about 80*F. He was still a bit bloated when I put him back into the tank, but in the time it has taken me to test the water and write this message the bloat has gone down, his color has returned some, and he's swimming around almost nonstop.

haha Needless to say I'm happy to see him acting normal, and now this message is almost un-needed. Though I'm going to take this opportunity to see ask a few questions.
Have any of you more experienced members seen anything like this?
I was going to get something to regulate the pH, Benny seems to be doing alright with it being a bit high, but I don't how if being in a more basic water for long periods of time will be bad for him.
I also have Tetra All-In-One Treatment tablets, but when I was at Petco, the guy said he didn't care for tablets only for the reason of the liquid will mix with the water much faster, and go to work faster. Opinions?
I have some pics of when he was in the bowl for the water change and bloated, and I can take some of him now if its helpful.
Thanks for helpin out a Fish n00b.
