Venting a room

I've been doing a lot of searching and they do sell single rome HVR's in Europe that would be ideal for a fish room, but I haven't found anywhere online that offers shipping to North America. You could always just vent the room with a regular bathroom exhaust fan that is controlled by a humidistat, but I'm curious to know what solutions other people have come up with.

More or less what I added. Though a HRV is not required by code in Canada (NBC 2012) but it may be required by a provincial code (not required in Alberta). It is a good idea though to have it installed in new construction.

There are many threads on here about retofitting a HRV to an existing house. The costs vary, but in most cases, the price would be worth it.
