Last night when I fed my betta, Sai, I noticed that his tail was all ratty and ripped to shreds. He looked like a Crowntail, but he is a Veil tail, so I was worried. I put in a new plant yesterday afternoon, and I think that might be the cause so I removed it. I'm still slightly worried it could be fin rot though. It wouldn't take hold that fast would it? His tail was completely intact that afternoon when I put the plant in. I'm treating with Melafix anyways, cuz even if it's not fin rot, I know it can aid in the healing of his tail. What are your thoughts? Is there anything more I should be doing? Here is a picture of him that I took this morning.
