hummm, you like big fish. i think your going to need a bigger tank

the naso gets way too big for that tank. the rest are ok but if you plan on adding fish then the trigger and loin are kinda too big and will limit future additions. its not a bio issue so much, more of a territorial issue.
FYI-lettuce is not the best thing to feed them. nori dried seaweed is great, maybe spinach if no seaweed.
