I have a full grown tiger oscar, And he eats just about anything even the eyes out of my one goldfish, He did that when he was just a little baby oscar. i breed mice and rats for my 3 snakes that i have and i gave one of the newborn mice to my oscar and he loved it, I gave him a few more the other day and he liked everything about it. Do you think it's ok to give him newborn mice as a treat? Cause i sometimes give him feeder fish but he seems to like newborn mice alot better then feeder fish. Thanks
