puffers with exposed beaks (dog face, stars & stripes etc)could be a gamble, the only other fish I have seen destroy a tanks was an 8" queen trigger that ws returned to my lfs after it chewed up it's owners 300 gal acrylic tank, and it proceeded to scratch the glass of the tank it was put in at the store!
This is more of the exception than the rule. I have friends who keep puffers and triggers in acrylic with no issues. With aggressives there are individual personalities, you wnot know until you try, if you get a problem child you could always return it for another.
Good Luck!
