I'm a beginner on modding and I created a entity named Fishy but when I spawn it, it stop and dies drowned, what should I add to my code to make it breath underwater and swim? Entity class: https://pastebin.com/MP9usA3m

You have to override canBreatheUnderwater and make it return true always. Anyway if you are making a fish like entity, why not taking a look at how vanilla implements water mobs? You can find useful information in the classes: AbstractFishEntity, WaterMobEntity and GuardianEntity
