Day 3 and so far so good. I just decided I would try it. My daughter 12 is. To save you time it’s like a vegetarian that eats seafood. But Vegatarians hate that reference. 

Urban Dictionary says:

Pescetarian is an omnivore who excludes poultry, beef, and pork from their diet but includes fish (and usually other forms of seafood like shrimp, oysters, scallops, etc.).  Because these people do choose to include meat in their diet (seafood is muscle tissue from a live animal and therefore meat), they are not vegetarian as vegetarians do not consume meat.Sally doesn’t eat beef, chicken, or poutry but does include fish and some other forms of seafood in her diet. She is a pescetarian.
