do you notice he does this more when aqaurium lights are on and room lights are off?
its because it see its reflection and thinks its another oscar and attacks
what i did once was get a good picture of another oscar and stuck it to the glass, see how after a few mins the fish changes colour and aggro

or hes a nutter

your 1000% correct!!

I only see him doing it when i get into bed, turn off my bedroom lights...the aquarium is set on a timer to go off at 00:00.

Well now i know!! i might try putting a mirror next to the tank lol!!

i heard that is also a good way to get the nuchal lump on my GT to grow!! (if he is infact a he)
