I would love to see a video of your little Puffer hoarding clam shells and then taking them out of your hand when you try to remove them from the tank.
The story was entertaining so the video would be hysterical.
He is really cute.
I noticed something that I never would have had I not seen the video. Puffer fish have eyes that are both in front like a predator and they can move them to each side of their head too. I've never seen anything with eyes that are both.
