OK to feed these snails to my giant mbu puffer?

[Mount_Prion]

Any reason not to feed these to my giant mbu puffer? They seem the right size and shell thickness to be a bit of a challenge for it.

Got em frozen in Chinatown pretty cheap.

think those are trap door snails or something like that, if the preservatives are not present its worth a shot
