The other day I posted for advice, my betta was suddenly hanging out in the bottom of the tank with clamped fins and very lethargic. This past weekend I went to the local pet store, where they told me that they change the water 100% every two days with the local tap water and that I could get a ph test kit (not impressed). I got the kit the ph was 6.5 this morning I did a 50% water change with tap water it has a ph of 7.5 to 8.0. Water temp is 82 degrees. In the last few hours my betta is hanging out in the top of the tank and seems more active. Her color is also a little brighter :D Fingers crossed this was the problem.
