Hey everyone, quick question, I recently acquired a new betta fish, the largest one I have ever seen anywhere from a friend, and while he was being brought over he started going belly up. I have him now in 76* 15 gal tank lightly planted, with gravel and sponge filter. As of right now he is still moving every once and a while. He can still swim up to the top for air, although I helped him in the beginning to get up there. The most recent update is that he swims up to the top and then floats back down or spirals or swims upside down to the bottom of the tank. Any idea on what the problem is,
Is he still in shock?
Maybe a change in the water?
Maybe In Temp?
I'm not entirely sure what it could be but thats why I'm here asking, Help me Pleaseee!!!!!
