First off deep blue...please lay off the smilies and little cartoons in every single one of your messages. Your posts are giving me a damn seizure every time I open a thread in 'Fish Health and Disease.'
Secondly, the plutonium and general lack of correct information ewurm gave out was his idea of a joke. I didn't think it was that funny, as after his first post (not the second with the verbose plutonium description in it), I could honestly see someone who's new to the hobby starting to freak out and irrationally spend a few bucks on some stupid medication when a few neon tetras will do the trick.
My solution: Get a few glowlite tetras or neons. They LOVE to eat Planaria.
