If a fish is free of white spot, it cannot give to another fish because it no longer has the parasite.

If there are free swimming parasites in the water, they can be transferred into another tank on plants, ornaments, driftwood and the water. But if there's no parasites left alive in the water, it is safe.

That’s what I had been taught. Shows to be careful with what you read. Thanks again for all of your help.
