Our Betta has been acting oddly lately. He seems to be swimming at an angle, and other times, he just looks really off balance. He is still eating, and he has clean water, and his location has not changed. Anyone who has one and has any insight on this, please let me know. I know they don't have a long life span but he isn't quite a year old yet. Any info. would be greatly appreciated as we have grown quite fond of "Sonic".
