" that some people see aquatic snails as pests which carry diseases and proliferate uncontrollably. Others see them as an integral part of a 'complete' ecosystem in tanks."
"Some problems people complain are mostly unfounded. They claim snails are carriers of disease and parasites that will affect their fish. The truth is only the case with open pond snails, were snails may act as intermediating hosts to certain parasites that come from bird feces."
Does anyone on the forum have any thoughts on this subject?

Actually I don't care much for fish in my aquaria. Some snails can be intermediate host for parasites, but I've never heard of that being a problem with aquarium snails. For marina snails, there are some parasites living primary in/on snails, but I've not heard of any in freshwater.
