oscar's stop growing at a certain size if kept in smaller tanks. The oscar that ate vegetables is still alive and is only 7 inches. He has no deformity at all.
Improper diet? Most oscars are farm raised, not wild caught this means they were not raised eating meat only. They can eat veggies their whole lives no problem because they were raised in captivity.
Cruel? An oscar will not continue growing in a small tank. I have met people keeping oscars in a 10 gallon for 4 years! The oscar got no bigger than 4 inches.
To make a fish live a long life isn't tank size. It is a good diet and CLEAN water.
so your saying if I keep a pet tiger that was born in captivity he wont eat me or kill me? I'm pretty sure wild tiger's main instinct is to hunt and kill. Oscar's main instinct is to hunt and eat MEAT. That ok, I will go feed my "Vegetarian Tiger lettuce,peas, and ect". I keep my pet tiger in a closet. I think he enjoys it.
Everybody, AquaPishFimp said he kept fish for 42 years?
