I have a small fish room also and I decided to go with an a/c wall unit and a bathroom exhaust fan.

When I was doing my research, they recommended that I do not run an A/C duct from the main unit. Something about salt getting to the main unit, not good.

I like it separate from the main house, that way I can control the fish room independently.

I'm current looking for ideas to get some type of humidity sensor to control the bathroom exhaust fan.

Ahh, just make sure that you exhaust to the outside, not the attic.
