Hello,
For the past week or so I noticed my Betta has stopped swimming around his tank, and is now the floating on the top of the tank. He will move around in order to try and get food, but he is staying at the surface.
He is also having issues eating. He tries to grab food but nothing is"fitting" in his mouth.
He has two large bumps forming on his sides, and they seem to be getting bigger. I do 50% water changes every week, and have had no water issues. He is in a 5gallon by himself. Water temps are at 78. It is also a planted tank and has a filter.
What,if anything can i do?
