well, i did just move his tank from my desk to my night stand an hour ago. but i took the wallpaper off, and it then looked like he was flaring at the heater, but i took that out and then i just got him flaring again at nothing. so i just fed him some. and he literally attacked ever little piece that i gave to him.
last night, i think it was, he was starting to look pale so i put some betta revive in the other night but before that i took about 20% of his water out and today he looks just like his normal self. like i tried to fed him last night and he just wouldn't go after anything at all. but then today, it's a whole new flame.
