should i buy some hermit crabs just for puffer snacks?

[ericjn]

I have a porc puffer, and this is a diff tank i have him in... The other tank had coral sand/rocks shells as the gravel so he would sometimes pick things off the ground to help keep his teeth be ground..... Now this tank is sand, so I need to find a way to get him to file his teeth would getting some hermit crabs help this at all?

What are you feeding him now?

Mostly brine and mysis....With spirulina. Ive thrown some squid and other foods inthere every now and then to give him a lil menu but im worried about keeping his teeth filed down so to say.... Oh all the food is frozen
