*** had him for about 2 1/2 years about 7 inches always was fine and active now he gets spooked swims up and down the tank seam extremley fast splashing water out of the tank and then he goes through the sand and gets wedged into some spot where i have to physically remove him from and other then that he just sits still.. :-?
Strange, I would definitely check the water parameters because something is stressing him. Have you made any changes to his tank? Or how about changes around his tank, like lighting or something different. I was thinking maybe you added a lamp or something and now the shadows are different on his tank and that's spooking him.
Also maybe get some dithers for the tank, that may calm him down. Maybe some giant danions or tiger barbs.
