Do you have a parrot fish pet?

What is a parrot fish? I have heard of angel fish, gold fish, but a parrot fish is new to me. I thought your discussion is whether do I own a parrot or a fish? Didn't really read that carefully. Anyways, I have a fish. It's a flower horn. It is sick right now. My dad and I think that it's allergic to shrimp. Because whenever we feed it, it gets sick. I just hope it will feel better.
