Please help my betta fish
Ok. I am getting really fed up with worrying about my betta so I figure I might as well ask. When I bought (rescued) my male betta from the fish store he had a blackish edge on his tail fin. Just that one and no others, although he did have a hole in his bottom fin. The hole ended up splitting all of the way down, but is now almost completely healed. The black edge however seemed to get a little larger (more inward on his fin). I figured it was fin rot and tried treating him with melafix. It is supposed to be all natural so I figured that I should try the least aggressive treatment first. It did not make the black area go away, although I couldn't tell if it got any larger. So, I ordered some Maracyn TC (tetracycline), and used this. I did two treatments and the spot did not grow, but it did not seem to go away either, so I figured that I should do some more research because I did not want to kill my fish with too much medication. Well, I haven't found anything. I may be just obsessing, but it seems as if the fin has gotten a little more ragged. Again, it is really hard to tell. This has not affected him in any way but I did notice recently that he has not been blowing bubble nests. I'll skip the whole story, but I found out that there was a ceramic pot in my tank that was causing the pH to increase (7.6 and my water is usually acidic). I took the pot out and am slowly trying to bring the pH back to normal. I don't think that this is the problem with his fin though because the pH must only have increased recently when I went back to my once a week water change schedule (I was doing more frequent changes when he was on the medication). Please help if you know what may be causing the discoloration on his fin, as I really want him to be healthy and happy, especially so because I don't want to have to do medications after he is moved into his new 15 gallon planted tank. Thank you.
PS: Right now he is in a filtered, heated, 5.5 gallon tank with a cover, gravel, and some artificial plants. pH is 7.6 (I am trying to bring it down now that I got rid of the problematic pot) and ammonia is 0. I will post pictures of his fin when I can get them on the computer.
