My dad's betta, Indy, just passed away from what I am assuming was flexibacter columnaris. I noticed 2 nights ago that he had white fuzz all over his dorsal fin (that's the one on top right?), so I did some research and concluded that it was flexibacter columnaris. I quickly isolated him and tossed him in a AQ bath. Yesterday I got some API Pimafix medicine and I thought he was doing better, but it rapidly spread and he passed away tonight.
My question is...
Do I need to sanitize his tank and everything in it? If so, how do I go about doing it? I have live plants in the tank. How should I clean the plants?
He also had a snail in the tank, which I have taken out and have isolated. Will the snail be ok? Do snails get flexibacter columnaris too? Will it be safe to put the snail right into the tank with a new betta after I get it cleaned.
I am not really looking for any suggestions on how I should have treated him... it came on so fast there really wasn't much I could do. I read a lot on the web and bought the only medicine I could find.
So, any suggestions on how to go about cleaning his tank so I can get him a new fishy friend would be greatly appreciated.
