Hey yall, so the freezer was recently cleaned out and I found a 56.4 Oz tub of new life spectrum small fish pellets. It's been in the freezer ever since I got it a few years ago and it expired December 2017. Do yall think it's still safe for the fish or should I chuck it? The freezer was a deep freeze and not like a normal kitchen freezer. I can post pics of the tub if ya want.
