There is a LOT of algae in the tank so he will be feed for a bit. I have a 12g reef with 2 Clowns, 1 Royal Dottyback, 1 Mandarin Goby, and a Cleaner Shrimp as well as crabs and snails.
My 34g tank is aggressive, just started it with Damsels and a Yellow Spotted Puffer so I think the 12 would be the only suitable home if there is enough room for his bio load. The tank is skimmed.

Ok so maybe for the next week or so he has enough food but for the long run he will out grow the food supply and the tank. He will get to around 5 inches long and need to be in at least a 30g tank according to live aquaria http://www.liveaquaria.com/product/prod_di...4&pcatid=94. Thats at a minium of 30 gallons with no other algea eaters in there.
So no he will not fit in the 12 gallon. The mandarin shouldn't even be in the 12g as they like to move around and graze as well. Liveaquaria again recommends at least a 30g tank for them http://www.liveaquaria.com/product/prod_di...&pcatid=551.
You really should start researching these things BEFORE you buy them and put them in tanks that are unsuitable for them. This hobby is all about patients so please aquire some.
And as for the 34g tank you just started it and already have several fish in it? Please tell me you cycled it first properly. I think you should get a better id on the puffer because I couldn't find one with that commen name and just so you are foreward there are only a few puffers that would be suitable for this size tank. So you might want to think about that.
