Male betta inherited all 5 gallons after in 2.5g of the divided 5 gallon tank. Now he sees his reflection all the time and Flares most times. Goes at the glass which scares me. How can I tone this down? Also he hangs at bottom of tank often, sometimes face down ass up(pictured I think) sometimes he just coasts and goes on his side then just goes back to normal. He eats fine and is responsive to me but again goes right back to obsessing about reflection. He's just a different fish now. Treating for ich as tank mate recently removed had it. Water changes/treatment daily just as precaution.
