well, there are several puffers commonly reffered to as tobies, though its probably the saddlebacked/valentini puffer. can you give us a more specific name, possibly the scientific name or a good description?
mmmm..... from what i've heard from people who keep the species, it is always a bit of a gamble introducing one. some eat inverts, some dont; some bother other tankmates, some don't. if you really want one you could try it, but be prepared if it doesnt work out, and if you do get one make sure to keep him well-fed and watch him (and your other fish) carefully, and remove him if you see any signs he's been causing trouble (e.g. bites in your other fishes fins, bites in your brittle stars arms)
