I have fed my Garter/Ribbon Goldfish for 13 years. Is Thiaminase a problem?

[drache]

I see absolutely no reason or excuse to ever use a thiaminase containing fish when there are already other things available that are totally safe without any additives!

I don't really either, but if I had a snake that only eats live fish, and I was on the brink of death with the flu and had to depend on others to buy feeders from a petshop for me . . . it's happened - thankfully I've not stayed ill long enough to make supplementation an issue
