These species should mix well together in a 40 gallon aquarium, although the Maroon Clownfish can get rather territorial and will make it difficult to add other fish in the future. The Maroon is more suited for a much larger tank to help curb its aggressive behavior. I would suggest a Tomato or Ocellaris Clown for your tank size.
Both fish will do well on a varied diet, which should include a staple flake and a good rotation of frozen foods, such as Brine Shrimp, Angel Formula, and Prime.
The water parameters of marine species generally do not vary. There are a small handful of cold water species which show up in the trade, but this is rare. You want a pH of 8.0 to 8.4, temperature of 76-80F, and spec gravity of 1.023 to 1.024.
The Maroon Clown can reach 6'' in length in the wild, closer to 4'' in the typical home aquarium. The Flame Hawk is similar in size, usually maxing out at 3-4''. Both are reef compatable, but Hawkfish in general can present problems because they tend to "perch" on corals, causing them to close.
To my knowledge, there are no visible sexual characteristics. This is true of most marine fish, but certainly not all.
Both of these fish are available almost every week at every LFS that stocks marine fish. They are probably in the top 10 of easy to find marine fish. Price should range from $15 to $30.
When selecting any fish, you want to first ensure it has been at the LFS for at least a week. Stand back and observe from a distance. Watch its behavior. It should not be scratching or twitching. The Hawkfish will probably stay perched, and will often swim behind a rock to hide when you approach the display tank. The Hawk should have active eyes, and will usually look up at the water surface waiting for food. The Clownfish may or may not hide upon your approach, depending on how long it has been at the LFS. It should also be eager to eat, and should respond towards the surface when you place your fingers up pretending to feed. Both of these fish are very hardy fish and generally arrive at the LFS in good health. They are also deeply colored, making it easy to see parasites should they not be in good health.
I would avoid generalizing the behavior of these fish with the other memebers of their family.
