Steve,
I've kept those three fish, plus old wifes, moonlighters, Shaw's cowfish, magpie morwongs etc. What kind of feedback are you looking for? The only species I've had problems with have been ornate cowfish - they seem prone to skin infections. I keep most of these at a temperature range of 65 to 68 degrees F. I've had less experience with Australian temperate invertebrates. There is a section these critters in my book, "Advanced Marine Aquarium Techniques". Ceretainly not the last word on keeping them, but probably a good overview.
