Odd behavior for an oscar
It seemed odd to me, but then again my Oscar is odd to begin with lol. He's a lot like me, I honestly swear he has OCD. If any little thing in the tank changes at all. Such as a bulb in the light fixture goes out so the lighting is dimmer all the sudden, or if I move anything at all in his tank. Then he goes over to the corner and actually lays on his side flat on the bottom and sulks like a just shoot his dog. The first time he did that I freaked and thought he had died lol. He really is one of the strangest fish I have ever had that's for sure.
