I have decations that was in another fish tank that the fish had ick in it. Is it allright to put the decations into another tank and the fish wont get ick from it or anything.
Let the decoration sit in a tank that is heated up to 28 C or more and leave it there for a week. The ICH parasite won't survive if there is no host it can attach to
I'm guessing that's decorations.... If so, why not just place it in boiling water for a couple of minutes and place it into the tank? That'd kill all of the parasites that might be hanging onto it.
