I hear oscars are very aggressive when paired up

[Nabbig2]

As I said, I hear that oscars are very aggressive when paired up for breeding, and I believe it. My older cousin once told me that he saw a tank where a female oscar was guarding her eggs, and a bunch of other large cichlids and the such were on the other side, afraid.
So I guess my question is that how big of a fish would a pair of breeding oscars try to fight off? I know they wouldn't try to fight a 3 foot snakehead. Would they bully a red devil, or a shovelnose? Thanks for your opinions/facts.

I find it hard to imagine oscars fighting off a red devil, but then I've never bred oscars before so I can't say for sure.

in my experiance oscars are mostly of bluff!

and i very strongly doubt that you can find an actual breeding pair of oscars!

but if you do consider yourself lucky!

Just about any cichlids are pretty aggressive when defending thier young

Yeah, Oscars usually aren't soa ggressive, but I think that totally changes if it's a breeding pair.

i think u will find that they will fend of anything when they have eggs,my red devils took on a 30 inch giant gourami when they had eggs

The Oscars will attempt to scare off more then fight of the female seems to get more agressive leaving the male to tend the eggs. But the will deffend there area

My Oscar fends off my Jaguar pretty good. My Jag has become more and more aggressive since I moved and the Oscar can usually hold its ground.

Breeding I guess for Oscars can get pretty brutal. They have a different way of breeding and thats usually why Oscars cannot be crossed with other cichlids.

Oscars act hard but they aren't really that tough.
