Two tiger oscars in my pond?

[Asianleful]

Can I keep two tiger oscars in my pond? The pond currently houses:
1x 3 inch blue channel catfish
2x 4 inch ID sharks
8x medium sized goldfish
50+++ guppies
The goldfish and the guppies are meant to be feeder fish so they'll soon be gone anyways. The picture I have below of my pond is what they're going to be in. I live in South Florida and it gets pretty cold down here, but since oscars also live in the everglades and deaths haven't been documented, would they live? So yeah, I just need some opinions!View attachment 686686

I don't see why not. How many gallons is the pond?

It's been a while, I want to say about 1000-1250 gallons but I'm not too sure. Should be around that area. It was either the oscars or a FL gar and I was told the gar would have to be kept warm.

An Oscar would be a good choice rather than the gar..

Alright, how long do they take to get full grown?

To get absolutely fully grown your looking at 2-3-4 years...it all depends on the fish..
