Does anyone really know:
Can Ich survive in an aquarium with no fish, no living animals?
I've have a 40 gal tank that my kids use.

Were there fish living happily in that tank before the additions? If
there weren't then you need to cycle your tank.

Ich need new hosts to survive. You can guarantee that ich will be dead
by 6 weeks, if not by 3 weeks.
