Vegetarians don't eat fish
BY DEFINITION:Vegetarianism is the practice of a diet that excludes meat (including game and slaughter by-products), fish (including shellfish and other sea animals) and poultry.
Pescetarianism is a dietary choice in which a person, known as a pescetarian, eats any combination of vegetables, fruit, nuts, beans and fish or seafood, but will not eat mammals or birds. Some animal products like eggs and dairy may or may not be part of a pescetarian diet plan.
So there you have it =) Do me a favor: When another pescetarian calls themselves a vegetarian, CORRECT THEM *hugs*
