Advice for getting started

Hello! I am in the greater Seattle area and am looking to get into the dart frog hobby. I have been doing salt water aquariums for some time at the nano level, so I have a decent understanding of patience to get things cycled for your pets, included making my own salt water.

First things first… any recommendations on a tank? I am thinking. 24x18x36 sized habitat to build and learn at first before going bigger.
