Kyle, you are a wealth of info! I have nothing to add, just reading and trying to learn... but I agree that variety is the key, from all we've gathered. That one article I read is supported by what you said above... that the cells rupture quickly in dead fish and so they recommended not feeding previously killed or frozen/thawed fish to garters that are known to carry thiaminase as the level would be higher. But it also said that gut loading the fish with vitamin/mineral rich foods offset the effects. Interesting stuff, all of it...
