  hello! i'm planning on going to a convention in july and would like to crochet a this fish hat. problem is, i don't know what 'type' it is or what to search for to find a similar pattern.

  would any of y'all happen to know what this style of hat is called, or know of a similar-looking pattern? (fin on the back can be added after :•))

Similar to simple hood, pixie-like.  A rectangle with sewn seam towards the back shaping.  Pretty much all the crochet fish hats are similar to this:
