Mine try to...but they spit them out. I think it's just the food competition instinct. Predatory fish...they're not really programmed to share, and as well they shouldn't, or they die in the wild.
You know how it is...something that resembles a consumable goes in the tank, all bets are off. It's a dominance thing too...hence why I have to separate my two O's when it's feeding time. The one will gobble up all the food even if she can't consume it just to deny it to the other. She also goes after food closer to the other Oscar even though there is food readily available right in front of her.
Of course...that could just be a woman thing.
