:'( I am so upset...I've been medicating first EM tablets( first week I had him) then Triple sulfa Jasper off & on since I got him. He came with frayed fins...which looked fine. Then with all of you here having trouble with fin rot I decided to read more about it. Yup he had/has it and last week he had a lot of fin growth. He "appeared" to be healing up...then wham! Yesterday morning he looked all chewed up again. He is in a 10 gallon with an apple snail & a tiny bristle nose pleco baby. The parameters in the water are what they should be. I was doing two water changes a week...he looked better. He is on his second batch of triple sulfa (a week break) This is SO frustrating!! I just lost Sammy, if I lose Jasper too. No more male betta for me. Just females.
