Psst psst, got my fish from Yewlin in Nov. I realize that the tail is slowly splitting. Any help? My tank is a filtered tank and every 3-4 days I will change 15% of the water. I threw a bit of ketapang leave only because I do not want my tank to be brownish in colour. Added about 5ml of salt but still slowly splitting. The ends of the tail do not tear, just that i can see the tail splitted.

There are no splitting in this picture because it was taken before the split happen. This is just a ST HM BF. not DT or CT so shouldnt have splits. Maybe it is fin rots. Tried the salt but really dunno how much I need to put. Later put too much my fish KO.

I will try to get a snap on the splits and put it up soon.
