Not sure of this is possible but it might be a good idea to update the care sheet on here with some additional information on feeding fish. Other than advising not to feed fish containing thiaminase, there is no information about feeding frozen/packaged fish to your snakes. It seems to be a very confusing topic and obviously there are many on this site alone who aren't 100% sure or in agreement about what to do with fish. Feeding silversides seems to be very common on this forum, so either many people are unaware of the risks posed by this brand of frozen silversides, or any fear of feeding these has been blown out of proportion. If packaged fish can be deadly to snakes I think it is very important this information be added to a care sheet. The sticky thread has been very helpful but I'm worried this information has come too late for many people. I'm not sure if one meal of packaged fish could kill my snake but I know I would be devistated if it did, and I would like to think I don't fall under the category of "questionable keeper."
