So on Monday when I got home from work I went to my betta's tank to feed him but he was not there to greet me as usual. After searching the heavily planted tank, I found him very lethargic on the substrate hiding in the wisteria. He came to the surface and I noticed that his right eye was swollen and cloudy. He was also refusing to eat. I tested my parameters and everything checked out there. I performed a massive water change to be safe and rushed to my lps and bought kanaplex. When I got home I noticed that his head was starting to pinecone and he was still refusing to eat. I am unsure if he has dropsy since his belly is not swollen, only his head (mostly the right side where his eye bulges). So I started the kanaplex that night. He became more energetic on tuesday and is eating but his eye and head are still swollen. I decided to start treating with epsom salt baths tonight. While he was in the bath I noticed tiny white specs on his body that I did not see on him in his tank. I am afraid that this might be ich aswell. I am fairly new to the hobby and have never experienced any diseases or illnesses before, so I am unsure if this is popeye, dropsy, etc and if I am doing the right treatment. The tank is 6.2 gal and 76 degrees. I do weekly 33% water changes and feed once daily with Sunday being a fast day.
