Ok, I was talked into this food by an lfs saying it will benefit my puffer and wear down his teeth. H2O Life clams on the half shell. Well i tossed one in my tank and my puffer looked at it, took a nip, then bailed out. No one in my tank will touch it. So, seeing that we dont have a reviews section yet, let this be a heads up, I wouldnt waste the money on this product. My puffer will seriously eat anything I put in there but not this stuff
