Yes, you can eat Oscar fish, but there are some things you should know before you do. For one, they are a bit of a bony fish, so you’ll want to make sure you remove the bones before cooking or eating them. Secondly, they are a bit of a fatty fish, so you’ll want to trim off the fat before cooking. Third, they have a very strong flavor, so you’ll want to be sure to add some other strong flavors to balance it out. And finally, they are a bit of a messy fish to eat, so you’ll want to be sure to have plenty of napkins on hand!
