cotton mouth

Well, when it rains, it pours. Think it's a sign I'm not supposed to be
going on holidays.

With the havoc going on in the big tank, I haven't been watch the smaller
tank to closely. The smaller tank has my smaller breeds of fish, bloodfin
tetras, few platties, danios, couple kribs, couple skunk loaches, few head
tail tetras.

Anyways, long story short, two bloodfins have a bad case of cotton mouth.
It's bad enough, their upper pallet (sp) of their mouth has fallen off,
don't appear to have the ability to eat. No other fish in the tank currently
show signs of cotton mouth.

So, couple questions. I'm leaving in a couple days, I have a hospital tank
currently set up treating my pleco for body fungus/bacteria, currently being
treated with Binox.

Three options:
1. Put the two bloodfins down as the damage seems quite severe. Fatality
rate of late stages cotton mouth is high, and it's said to be contagious.
2. Move the two into the hospital tank, start them with treatment of Binox.
3. Treat the whole tank with Maracide or Binox, as cotton mouth is deemed
contagious by many websites, even though no other fish show signs of cotton
mouth. Treatment would have to stop Thursday night, unless treatments are ok
to leave unattended for a week.

Anyones opinion?

Thanks
