I've realized that Bahari is blind.
He eats fine when I help him find his food. He no longer follows my finger and he runs face first into tank decorations. He reacts to light and movement, though. He is lethargic and listless when I am not actively doing something with him usually. When he does swim around, he just keeps running into decorations and the walls of the tank. I haven't moved any decorations and he still is able to find his plants OK. He likes to sleep in the plant I have in the back corner. That is usually where he's at when I wake him up.
I've PMed both Sakura and OFL trying to figure out what may have caused this... I also PMed DramaQueen because Sakura told me she also has a blind Betta.
