Looks like Marty's eye is finally subsiding, and returning to it's normal size. I'm letting the Maracyn Two work it's course through the tank, and then after this weekend I'll do a water change again. Good lord, I wonder how I'll be if we have kids. :) (NEWS FLASH: Little Bernouli now has continued nasal drippage. I'm thinking it might be a cold, but we're not sure. I'm medicating with a children's cold medicine, and will advise on the results. Wish me luck!)
