Special fish cubicus boxfish

[jimbo222]

unfortunately my tank is only a 40 gal and the flow is a little much for him.
im also worried that he might eat my corals as the tank gets more crowded.
iv'e had him for 2 weeks and he never nipped any of my corals.
so i guess he's ref safe. but as i add nicer pieces im getting nervous.

the lfs did not give my wife all the info as she knew nothing about fish and wanted to purchase me a gift.< oh ya and accompanied this fish was a dragonett.> fish stores should know better then to sell two of the more difficult fish to care for to someone who knew nothing about fish.
tank is a couple months old but im lucky to have some pods so dragonnet should be ok.
