i figured out what's wrong with roger. and now adolf too. ich. they've got ich.
i woke up this morning, well, this afternoon, i guess (1209), and roger looks like he lost a fight with a salt shaker. thanks to google and koko's goldfish world i learned all about ich. and it's icky.
so after a trip to a fish store, it looks like a smurf exploded in the tank (and on the wall... oops) and i had to change the filter. i hope it helps. :(
wish me luck.
