My betta, Sr. George is almost 2 1/2 years old and has recently started getting really bad fin rot and got pop eye on saturday
As soon as I saw the swollen eye I changed the water and cleaned everything really good in his tank. I have him in a 1 gallon tank with a heater that is supposed to keep the water around 75F and a light. The tank came with a filter but he didn't like it so I took it out. I change his water every monday and use a dissolving tablet water conditioner. I went to the pet store but there are so many antibiotics I wasn't sure what to get and the workers there didn't really know what to do either! Please help I'm freaking out!
