Keep things in perspective a 180 gallon is a nice tank but not a large one. The shape and dimensions are also important. many of the 180's are only about 18 inches wide making it uncomfortable for any of the larger chiclids to swim and turn comfortably. I would humbly suggest you aim for the mid range sized fish they will be happier and less stressed- Hey bonus you would now have more options.
