Yes actually, many different types of algae loving fish will gladly munch of lettuce. Be warned though, there isn't much nutrition gained from eating lettuce, so its not really worth it.

It depends what type of fish you have.
For all practical purposes the answer is no. If you mean to ask if fish are harmed by lettuce, they are not. If you mean to ask if fish will eat lettuce, the answer is no for virtually all fish, but I would not be terribly surprised if there were a few species that would eat lettuce. Fish are generally not vegetarians. Even those that consume plant food would want something with more carbohydrate or protein than lettuce.
