I thought the same as well. Then i looked it up and surprising enough its an acceptable source of food. Not much more details than that.. I think it should only be fed as a treat every once in a while. Fish in general are very hard on a puffer's internal organs, especially the kidneys.
Feed a more varied diet. Main staple of crustaceans is the best practice.
I'll look more into the silversides though.
