Okay, I bought a Halfmoon Male Betta at Petco July 19th. He seemed happy and healthy, but I noticed his tail fin was very slightly choppy. I just assumed that was his tail. It then became choppier and choppier until I noticed a pin hole in his fin. That sure ripped within hours. I changed his water, then I bought him medication - Tetra Fungus Guard, and put it in his tank. That wasn't working, so I went out and bought BettaFix, did a 50% water change, and followed the instructions on it... that didn't work. I then noticed him getting worse, so I took extreme measures and did a 100% water change, rinsed every thing really good, and put in some fungus guard, and aquarium salt, hoping it would work. Then to my surprise, I woke up to see him extremely worse. His attitude hasn't changed. He eats like a pig, swims happily, and loves attention, but that pesky fin rot is tearing him up. I don't know what else to do.
