mudduc,
Well the thing is that, my local pet store, Petland, just have the mice in a 20 gallon long. I'm pretty sure there are a few hoppers in there because I'm assuming they continually breed. If that's the case, I'm pretty sure I'll be okay feeding them live hoppers if I can just grab the small ones (weekly visits to check). So until furthur notice, just keep them on live unless you suggest otherwise.
