I am in agreement, however the puffer isn't the only problem in the tank. Every fish currently in there needs a 6' long tank or more. Try taking a look at Aquarium Fish: Tropical Freshwater Fish and Saltwater Fish for Home Aquariums
for what size tank fish need. They are quite accurate on their tank sizes.
If you are dead set on keeping your fish, it's likely that not many corals will be able to go in there depending on the type of triggers.
