oh okay then lol! His name is Christmas, the 4th boy down is almost the same as him (not quite as much green as Christmas but looks way nicer in life than the photo, he is Fireheart and is a DTHM) I cleaned their tank this morning and now feel totally depressed

Christmas and the second boy down have fin rott, two of my others already had it when I bought them and they are being treated. I just do not know what is going on because I keep my tanks so dam clean! so it defiantly is not from poor water conditions, maybe the ones I bought spread it to them, I don't know but it is driving me crazy I just want them all to stay healthy, I've owned so many bettas over the years and never had this trouble.
