I was reading a few websites about dog face puffers and one site was saying that they are reef safe (i knew better than that...) and sure enough...i had some hitchhiker polyp in the tank on a rock....in less than 5 mins of putting him in the tank that polyp was gone! Luckily I did manage to find some snails that are twice as big as he is
At the LFS he would come up to the top and do 'tricks' now he looks like he wants to spray water in my face when i open the lid!
