Shannon,

I don't think thiaminase will appear in fish if it's not there to begin with. It's not the freezing process that creates it.

I miss feeding my radixes live fish but the enjoyment of watching they hunt isn't worth their death.

While I was out Herping yesterday I came across a field mouse. I was able to catch it and kill it. The whole time I thought my Speckle or JW (my two biggest girl) would love to have a full grown mouse. On the way home I knew I was going to freeze it for a couple of months just to make sure parasites weren't an issue. At one point it hit me, I had no idea what this rodent had be eating or what other problems could occur with feeding it to my snakes. Out the window it went. Better safe than sorry. I have a very difficult time losing any of mine. I don't want it to happen because of something I did or didn't do. Safe foods all the way here at the T.r adix Ranch
