Dehumidifier in a Fish Room

If heat isn't an issue without the dehumidifier and you have a way of exhausting air outside from the fish room I'd suggest just using an exhaust fan to control humidity. By venting air outside you're exchanging air, new dry air will enter the room as needed from the rest of your house. No need for an HRV, it really won't help in summer months, only winter and more than likely humidity isn't much of a concern in the winter.

Totally agree with you. I run a 500 CFM exhaust fan, works great and the room air is replaced by the air conditioned area in my home.
