My betta is in a 10 gallon cycled tank. His back fin looked a little ragged yesterday so I added melafix and I also added some today. When I got home this evening it looked much worse. What else could be going on?

Any advice guys? The only change that I can come up with is that he is in a bigger tank and there is a rock in the tank, but I have the same one in my other tanks too with no problems.
 
I don't know whats wrong with it thats what I'm trying to figure out :o ! There is nothing in the tank besides him and the decorations that have been in there since I've had him. There is a large rock in the tank that is new, but I have the same one in my other two tanks and it has never caused a problem. The nitrite is 0, amo. is 0 and the ph is around 7.4 (stable) I am not sure about nitrate, I just realized my kit is expired. I do water changes, vac. always condition the water. I did buy a plastic reptile cave that I was told was safe for the tank, but I have since taken it out, that couldn't have been a problem could it? The only real change has been the melafix!
 
I have had similar problems. I have a male betta and the water parameters are completely fine. I don’t know why in the world his fins sometimes get messed up, to be honest I have had him for almost a year now, and he has never had perfect fins. When I treat him with Melafix, his fins just get worse. So I stopped the Melafix and just let him be the way he is. He eats fine; he is perfectly healthy as far as I can tell. I've never found out what it is that’s causing this; I thought I was the only person who had this problem.
 
I think I'll be staying away from the melafix, at least for the betta. They fins looked alot better today, its strange that they can go from looking like they did to such a huge improvement, almost overnight
