So my betta Roy is a small veil tail royal blue male betta fish. So a couple weeks ago I noticed that his tail is falling a part. I took out the plant that I thought was causing this to happen. I put in a soft plant that shouldn't hurt his tail. As I was getting ready to leave for a mission trip, I noticed that his tail was starting to fall apart again. So I went to wal-mart and got Quick Cure Fast Relief for Ick and Protozoan Parasites. My mom has been putting in 1 drop everyday, while I was away for a week. When I got back a few minutes ago I noticed that his half his tail has disappeared. He's a rather small betta at a little less than 1 inch. Any idea why his tail is disappearing?
