I've had my Betta for about 4 months now. I have recently (about two weeks) been treating him for fin rot with aquarium salt I used Melafix for a couple days but then heard some stuff that it was bad for the fish and was advised not to use it. His tail doesn't seem to be getting worse.
Now here's, another problem that I've noticed for about a week or so now. My fish stays at the top of the water and when he gets startled he seems uncordinated when he swims and goes upside down and stuff, some time just tilts a little on his side. I also noticed that he can't seem to stay at the bottom of his tank and just floats back up without trying. He also has not been eating for the past three weeks. He is still alive. He kinda runs himself into the side of his cup when I take him out for cleaning but I think that's becaause he's startled.
He is in a 2.5gal jar and I use aquasafe and aquarium salt to treat the water. It is a heated tank and it kepy at 73 F. Its a pre set heater because I do not have enough money for a better one right now. I have tried feeding him freeze dried bloodworms and pellets. Have also tried the garlic juice thing. He has no plants and I clean his tank daily because he is sick. There is no filter system.
I don't really know what to do with a fish that is not able to swim to the bottom. Help? Let me know if you need anymore info. He also has blue "strips" on the side of his face on bith sides and they look exactly the same so I don't know if these are marking or something else because they are symetrical. He had thin blue lines on his face when I bought him.
