I have a 90 gallon tank that I am currently running a fishless cycle on. I was wanting to put a Sun catfish and an Oscar in the tank. My local pet store has a 6.5" Sun cat that I was thinking of putting with a 2" Tiger Oscar. I figured with the cat's size advantage the O would not be able to eat it even if it reaches 10" in the first year or so. What are your oppinions on this combo.
