I'm not an allergy specialist, a doctor, or trained in lung problems- but I've spoken w/ several people who are and I've been told the more the merrier.
I'm in Utah (a high desert) where it is very arid and humidity is quite low, the doctors and allergy specialists have spoken out against de-humidifiers.
It's my understanding that dryer air is bad for the lungs. As mentioned above keep up on water changes to keep smell down, and clean the bottoms of your lids regulary to reduce mold growth.
If your dad is still adament the fish tank humidity isn't healthy talk to some professionals in your area-nothing like a person in a lab coat to change the opinions of people w/o lab coats (see the milgram studies from the 1950's, authority figures are able to make people do crazy stuff).
