Answer 1

That depends on which "fungus" you have. Saprolegnia and Achyla are present in most tanks, so if it's that, it's already in your new tank. This rarely attacks healthy fish, but will infect those that have wounds, are stressed by poor water quality or parasites, or are already dead. You can easily find out if this is in a tank by getting a container of the tank water and adding a sesame seed or shrimp pellet. It it's in the water, your item will be fuzzy in two days. Here's a photo of what this looks like o a dead bug: http://www.visualsunlimited.com/images/watermarked/227/227311.jpg and on a fish: http://botit.botany.wisc.edu/toms_fungi/images/saprolegnia-perch.jpg

Your fish could also have Columnaris. This is a bacteria that looks similar to the Saprolegnia, but the strands aren't usually as long and in Columnaris, and the edge is circular where in Saprolegnia it's more irregular. Here's what that looks like in the early stages on a fish (page down to photos): http://www.fishjunkies.com/Diseases/columnaris.php The center becomes a red sore in later stages: http://fish-helpline.co.uk/photos/img211.jpg You can treat this with Furanace (generic name Nifurpirinol). This may be something you could introduce to the other tank if this is what your fish have.

NOTE: As long as you have water on your hands (or net, or other tank equipment) there's always a possibility that anything from one tank can be introduced to another. A good rinse with hot water between tanks will go a long way in preventing the spread of disease and parasites.

Answer 2

possible. it is even possible even if you hadnt [ut your hand in both tanks. the farther apart the less likely.
