walmart!!! they were actually supposed to be $0.78 but the lady was nice enough to just charge me for one.
i caught aeryn staring one down this morning. i'm on lunch right now. i dropped in some romaine lettuce and checked on everyone. at first i just saw one, but then the other two scampered out. they are hard to see and take pix of :p i assume because the smallest one is about john's size they're just not interested (yet).
but they did a really good job at cleaning up my tank!
