aww Im sorry I hope he pulls threw,Update:
Bo isn't doing too well. The worms have been killed but he can't expel them, so he's doing a lot of bottom-sitting with clamped fins. Still eating, though. If that stops I'll probably end his suffering with the clove oil bath. He's been through a lot, and may be about four years old which is typical life span for a ram, I believe.
I really hate these parasites...
after 3 doses of levamisole, i have no visible worms, one of the worse apistos had stopped eating but started shortly after the second dose. I am now out of Levamisole, they are still in QT eating like pigs im to afraid to put them in to my main tank,..going to wait a few more months i would be devastated if i put them in my 65 where they were planned on going and they infected my main tank!.
hope yours starts to turn around!
