It depends on the oscars personality and how well it is fed really IMO. I wouldn't worry about the blood parrot so much. Those algae eaters are really fast and grow pretty quick too. Put a few more decorations in for small hiding places and I don't think you will have to worry.good luck with your new fish

A well fed oscar will still make the attempt to eat a fish it thinks it is smaller than itself. I've kept a couple of oscars, and even with rounded bellies, they still stuffed itself with a fish it thought that it could eat.
I got my oscar yesterday. It looks health as well. But I also have 6 zebra danios with it in the tank. My oscar only tried a couple of times to chase zebras, and I fed all of them tropical fish food so far. I am going to get some small shrimp today for my oscar. Oscar didn't eat any of zebras yet. Is there anything wrong with my oscar? I hope I did not get a vegetarian oscar.
