I've had my betta over two years and all of a sudden he is laying on the gravel with his head in the air vertically. I have tried fasting him and water changes but nothing is working :-/. I have a 5.5 gallon tank with a filter and heater set at 82. I have fake plant decor and a live plant to add oxygen to the water, I also have two mystery snails in the tank to keep my betta company.....I don't know what to do to save Barney Jason (my betta) please help!
