Ideal fan to vent a fishroom outside

[lastlight]

I'm looking to buy a fan to wire to a humidistat. I'm not sure how often the thing will be operating but I don't want anything REALLY loud and I also want something reliable. My fishroom is maybe 50 sq ft.

Seems the options are a normal bathroom fan and the fancier inline ducting fans (Fantech etc). I'm not sure your average bathroom fan should run as often as this may require.

I'd also like to purchase this locally in Calgary. Thanks!
