Can you mix Oscars...

[CrystalClear]

with any other type of other fish? I am getting a difference of opinions from different fish stores. Some say you can as long as you introduce them at the same time and some people say they will only go by themselves. A friend of mine said they might go okay with Plecos or other bottom dwellers, but was unsure. I have a 75 gal tank and plan to get some type of Cichlid. Also how many Oscars would you put in a 75 gal? I know they can get to be 15" with right tank and conditions.

Thanks
