Tankmates for Oscars

Question
I want to buy an oscar. I already have a 240 litre tank with 2 Bala sharks, about 12 - 15cm long and a Fire eel about 20cm long. Are they big enough to keep a oscar with.
I am affraid the oscar will outgrow them and eat them.

Answer
Hi Chris...
You are right. Oscars will make food out of those fish real soon.
I used to keep an Oscar with a Discus and a Jack Dempsey, but you need at least 75 gallons per fish.
Oscars grow to 15 inches and eat anything smaller than themselves :-)
