hi i have a small 5 inch Oscar and was wondering if i could put in a small green sunfish with him im not very concerned about the sunfish but is it okay for the safety of my Oscar?

any one even if its just an opinion?

I would say yes
Both should be ok

ok thank you very much

might you be refering to the native north american sunfish? and do you have a scientific name for them?

yes there scientific name is Lepomis cyanellus

I had a sunfish for a year when I put in my red oscar.
Oscar became the boss, but tolerated the sunfish.
My O wouldt be handfed and the sunfish was allways catching the scraps and ocasionally took food out of my hand.
Problem was my sunfish terrorizing my Silver Dollars, with the Oscar things were fine!

ok thats that helps me a lot my tanks looking empty so i thought id go catch a sunfish

hey guys it ends up i caught a baby bass have him in a ten gallon for now was wondering if i could put it in with my oscar hes about a inch and a half bigger than my oscar??

My sunfish was 3" when i got my 2"Oscar. Things went real smooth when I put them together.
When there so small all they care about is food, not fighting. I say: keep a close watch and try it.

any advice on keeping a 7 inch bass and a 5 inch oscar???

You got me there...I don't know.
It seemed my sunfish knew the size my oscar would get from the beginning.
And treated him with such respect.
But I can imagine it to be the otherway around, seeing the aggro behaviour in my Sunfish.
