We don't really bother with an OpenFish driver in the shoulder pets ourselves, because they don't swim, they don't take hovertext well (it ends up embedding itself in the side of your head!) and without swimming there's no reason to put them in the aquariums. But, hey! If you wanna use a variant on the code in your own pets, have fun with it.

One of the joys of community creations are that they go places the official catches don't.
