You need almost perfect water conditions for anemones and coral, extremely high watts per gallon, and special food for anemones. You need to wait at least 6 months to a year before you add the anemones and coral, because the tank needs to be fully cycled and conditioned, and all take time. Are you sure they're raised in 100% saltwater, and not brackish? You probably know this, but you cannot add most anemones and coral to brackish tanks. If this is your first tank with anemones and coral, I'd add them very slowly, because whether you think you will or not, you'll make mistakes (everyone does their first time ). Also, check to make sure that puffers don't eat coral or anemones, something tells me coral isn't so safe in a puffer tank.
valdok ur right...i'm not so sure about green spotted puffers considering there is no corals in brackish water but i know ur not suppose to keep porcupine puffers w/ them so i guess it applies towards them too
