Hi everyone. I have a betta who I've owned for a few months now. I had been keeping him in a 2 gallon tank and he was thriving. However, I wanted to give him a bit of an upgrade so I moved him to a 10 gallon tank with a filter and heater. I had had a different betta in it previously but did a probably 90% water change before putting in little Shogo. The previous betta had never had any problems and he was in the tank for over a month. He had been in the tank about 4 days and I'm noticing a rapid problem with his fins. I attached some photos though the last 3 he didn't exactly want to cooperate with me taking pictures. He was in a small container for those three because I really wanted to get him out of the tank, as the issue appeared to get a lot worse from when I saw him before my morning class.
I guess what I want to know is, is this fin rot? Should I not put him back in the 10 gallon tank? What could have caused this etc.. I feel so bad for my little guy ): I was worried to put him into a new tank because he was doing so well in the old one.
