Does anyone have experience keeping an Oscar without a heater?

I have some local fish in two tanks (50g and 125g) and the water is room
temperature (around 64). I was wondering if an Oscar could live in such a
tank.

No. Ideal Oscar temperature is about 78 degrees F. When the aquarium
temperature drops below around 75, he'll lose all his color and lie
down on his side in the gravel. The stress would kill him in about a
week. --Mark
