So, if you saw my thread here http://www.bettafish.com/showthread.php?t=104383&page=2
you know that I was wondering if Buddha was used to the cold since he's constantly having cold water in his tank.
And i started trying to adjust his tank temp. a little bit during eac change to make it warmer. Those days that he was sick, I was putting warm water in his tank.
Well....I used a thermomter...the "cold" water was in a 77 to 81 range, and the "warm" water was almost at the 90's.
....By using my own bodily temperature testing, I could have killed my fish.
And I would have blamed it on something else without knowing that his tank was perfect and I was doing unneccessary things to it because I thought it was cold.
I just feel like a terrible owner now, and a bit of me doesn't feel like I deserve another fish after this
