Hello,

Today I bought a bag of frozen Sally's Silversides from Petco. I have only bought one bag before, so I'm not sure if this is a big deal, but we bought the same size of fish as last time, but they were quite a bit bigger. They would still be small enough for him to be able to eat them, but that's not the only issue. They are yellow, not silver. I have never seen yellow silversides. I am leery of feeding them to my snake because of their sensitivity to thiaminase. Anyone know if this is normal? Thanks!
