I'm pretty suprised that someone hasn't at ours. Oh and our wal-mart don't have weird blue water. lol, ours is just plan old tap water i guess. i don't really know. I think that blue stuff is supposted to keep them somewhat healthy. but i'm not completely sure. hm...lets see, i also forgot to mention that this man brought some liquid detergent down my isle, and the top wasn't screwed on...and needless to say it spilt all over the scanner, so it's temporarily broken. lol, oops. it wasn't techniqically my fault. lol, oh well. i know that didn't have anything to do w/ fish. but that's annoying. lets see, what else happened, there was something else that had to do with the fish. can't remember what it was though, watch i'll remember it right after i submit it.
