Yeah, in terms of rental agreements, fish don't normally count, IME. I've always thought that was a little silly. When my family and I were considering moving, we looked into a rental townhouse-- the landlord told us that we could only have one "uncaged" animal, but could have as many fish/rodents/other miscellaneous caged pets as we wanted. We had three dogs at the time, so we didn't move, but I suggested getting one really big cage and dropping it over the entire house as a solution. Then we'd all just be caged pets. >_>
