I am thinking about adding a porcupine puffer to my tank (29g). I will eventually be setting up a 150 and a 50 that I also have. I have a clown, yellow tail damsel, couple of emerald crabs, a few snails, a coral beauty, 4 anemones and a starfish, couple of featherdusters. The puffer is pretty small- I have fallen for him over the past couple of months at the LFS. I know he's not really reef safe but I am thinking that since he is small now I could keep him well fed and hopefully out of trouble. I think he'll be a threat to the starfish maybe. Does anyone have any experience with these puffers? Advice?
