Help Please someone....My poor Betta has been sick for 3 weeks and seems to be getting worse. I Have him in a filtered 1 G tank that I change 2X per week (Ix whole tank cleaned and 1X 50% change) and I check levels daily b/c he is in a small tank. It started as tail/fin rot and it has steadily becoming worse. He now has a sore on the top of his head (which I think was caused by him touching the heater) and also has som film on him. I have been treating him with salt and Melafix and it doesn't seem to be working. I am planning on getting a bigger tank tomorrow for him as to cut down on the "trauma" of constantly changing water. Does anyone have any other suggestions? Also, He doesn't seem to be eating normally anymore...
