I have been kicking around the idea of getting a Mandy, too. As such reading up on pods. Several of the articles I have found indicate that the temperature at which they do best goes from pretty darn chilly, (which I don't recall the number, my tank will never get there...) to 82-83 degrees farenheit. This is what worries me, as I don't have or want a chiller, and right now my tank is running between 81-82.
