My 1 year old Betta has a white cotton-ish area on his tail between the top and bottom fins. He's does not act sickly, but is a little lethargic. I used Pimafix for about a week and saw significant change, but his 10 gallon tank got quite murky. Since I know it helped I want to put him in his own hospital tank away from the 4 ottos and plant life in the 10 gallon. The fish bowl holds about 3 liters. How much Pimafix is safe? Would 0.6 ml work? I also have Super Ick Cure. Would that be better? Do I need to worry about the temperature before relocating him? I also read aquarium salt with the medication would help, is this true? Since he is as old as he is, I just don't want to hurt him and I will admit, I am a beginner at this.
Thanks in advance.
