Hello, this is (unfortunately) my first post because I don't know where else to go. My poor betta Charlie got sick a long while ago, I would say about a month ago. At first I thought he was just constipated due to being overfed pellet food. He was still able to swim but was staying on his side. He was in a 29 gallon tank with my tetra school, no fin nibbling or aggression from either party. He was in there for two months I would say before this all started. He became lethargic and like I said, floating on his side but still able to swim about a month ago. What I think caused the onset illness was the tank being too cold because my thermometer was showing me incorrect temperatures. I set up a 10 gallon tank (smallest I had) with the heater set at 77 and got a correctly working thermometer. I have a slow filter going as to not disturb the water too much for him. He seemed to be doing better in the small tank once I transferred him, then all the sudden it looked like he had fin rot. Now his color has completely changed and his beard even looks dilapidated The temp remains at a constant 77 degrees and I do partial water changes every few days. Ph has been a little high, around 7.3. Ammonia seems to be at 0. I tried some medicine (microbe-lift herbal actives artemiss 100%natural expellant for bacterial diseases). I have used it for 10 days and have had no success. His color has gone from his vibrant blue and red with flowing fins (elephant ear betta) to green and having half the fins he used to have. I don't know what I've done so wrong and I feel like a terrible fish mom 
none of my tetra have been sick or showing signs of sickness. I'm sorry for the long post. Thanks for any help.
