How to stop Geckolib animation loop.

So i made an alligator gar and an animation for when it flops on land. I set up this procedure so that it always plays when the entity is on land. It works, but the problem is that if the fish re-enters the water, its still looping the flop animation. Pls help.

Here's the procedure I used btw. It's in the Gar's entity tick update.
