Which is why I cycled to the full 2.0.
Is this your first Porcupine? They are so fun, we love ours. He will come to you when you walk up to the tank and zig zag back and forth looking like a happy puppy. When you feed, he will sometimes spit water at you. Mine will actually make the front of my shirt wet at times. This is because in nature they blow water into the rocks to flush out prey. I have some long polyp GSP in my FOWLR tanks (I know that technically makes it a mixed reef) and he will sometimes lay in it like it’s grass.
Try not to startle them as it is said to not be good for them to puff up, but I have had puffers puff with no problem, but if they do make sure the deflate in a short period of time. If not google as there are methods to help them deflate.
Mine loves krill, but now will eat everything I feed. Squid, frozen shelled shrimp, silversides and krill. I also feed mussels and little neck clams once a week or so. Puffers need to chew on their shells to control the growth of their hard beak.
