Ok, so, I have a giant plakat. He was in a 5 gallon tank with proper filtration and proper levels. Then I started to notice that he was getting these gray splotches on his sides and his lower fin. I removed him and put him in 1 gallon of water treated with dechlorinator and AQ salt. He got better in about 3 days of daily water changes with this mixture. I then noticed that out of nowhere, the gray splotches returned WORSE and the gray areas on his fins are now full blown holes...This happened in about 1-2 days after he started to look better. The crazy thing is, is that the splotches reappeared in the SAME places they were before. He wasn't clamping up at first, but now he's clamping a bit, and seems to tire easily. He still has a good appetite though.
I can't get to the store until saturday, and have been told to look for 'BettaFix' or 'Melafix' but I don't know what's the best way to go about it.
I have several bettas, but this one is my VERY favorite. He's usually kept right next to my bed. I love him VERY much and am VERY worried about him!
