No no no no!
I posted this a couple of weeks ago - http://www.bettafish.com/showthread.php?t=74710
and got excellent help from OFL.
Today, I was sitting and watching the boys. Nero in particular, since Octo's very happy and other than the occasional bite, has nearly stopped tailbiting.
His eyes are almost completely white now, with small pinpricks, which I assume is for the pupil. His gills are green, and I noticed an alarming new development. He has white fuzz on his upper lip. It doesn't look like fuzz, more like a thread or fiber. But I have no idea how anything like that could've gotten in his tank. In any case, it looks like it's sticking to his lip. He also has faint fuzz on his dorsal fin.
The tank specs again:

Hikari Betta Bio-Gold pellets
How often do you feed your betta fish?
Four pellets twice a day with one day of fasting per week.

Every few days, and siphoning the poop in between.
What percentage of the water do you change when you perform a water change?
50 to 75 percent
What type of additives do you add to the water when you perform a water change?
Nutrafin water conditioner
Have you tested your water? If so, what are the following parameters?
I haven't done that yet - I'm doing that tomorrow.
Symptoms and Treatment
How has your betta fish's appearance changed?
Cloudy eyes with a whitish film, green markings on the gills, white fuzz on lip and fin
How has your betta fish's behavior changed?
None that I've noticed. He might be having difficulty finding his food now - he hangs out very close to the trapdoor at feeding time.
When did you start noticing the symptoms?
The eyes and green gills - July 9th. The fuzz - a few minutes ago.
Have you started treating your fish? If so, how?
Not yet - I wanted to get opinions and tips on how to treat
Does your fish have any history of being ill?
Cloudy eyes and green gills.
How old is your fish (approximately)?
Maybe six months to a year old?
The tank has a snail to help with the BGA, and it is cleaned frequently to maintain water quality. There is also a moss ball, which I QT for a few days before putting in. Everything is just how it should be.
I have no idea what to do. I keep googling and nothing's popping up. I'm at the end of my rope. I can TRY getting pictures in the morning.
