Speaking for myself I'm not sure how they came, but it's probably the same way aquatic vegatation come --- primarily by birds, and it is possible they came from the transfer of new water that came with fish transplants.

Snails can be part of a parasite cycle which produces the yellow and black grubs we see and other parasites in fish. However, for the most part these parasites are just unsightly, and the fish seem to be able to tolerate them well. You should be able to find all the information you need on this by doing a word search on the internet.

If pigs could fly bacon would be harder to come by and there would be a lot of damaged trees.
