If you do not plan on keeping, please don't buy!
TRe, I have to agree w/1979camaro on the puffer, as well I notice you also have a 30gal SW with an undulated trigger, yellow tang and a naso tang. First of all I really hope you plan to get ALOT BIGGER tank in the very near future, the 30gal is not suitable for any of the fish you have in there for long term. The trigger can grow to 1', yellow tang 8" and the naso tang 1 1/2'. It is just cruel to keep them in there and if you don't plan on keeping them you shouldn't buy them in the first place; Sorry about the lecture, but they are living creaters and should be treated as such.
