Hi! I'm constructing a large tropical vivarium for dart frogs out of wood. Its 42" long, 30" tall and 16" deep. I want to install small fans to allow air circulation and ventilation. Where could I find such fans, how much do they cost, and what would be the best way to go about installing them (both to protect the dart frogs from the fan, and so that it will look asthetically pleasing because the vivarium and its stand are made of furniture quality wood and are made to furniture quality standards. Thanks for your help!
Mike
