My wife's Porcupine Puffer is a little character too
They really make it worth setting up a fowlr (actually Poofie is how I got my wife to think setting up a fowlr was HER idea
)
He mostly stays in one of his caves or tunnels but as soon as we go near, especially if we have a bamboo skewer (how we feed him Krill & Prawns), he comes right out & starts to beg. He is especially good at getting Irene to overfeed him
Thanks for sharing the story & picture. Our's only puffed up when I first bought him at Hidden Reef and when I added a Purple Tang into "HIS" tank.
