just bought oscar fish yesterday. drive it home for about 30min. then the next day, it just lays on the bottom of the tank and looks motionless. but it always stood its dorsal fins when i come near it. is this normal for oscars when they are stressed out?
as u can see on the image,


wht's wrong with my oscar ?!
