Thank you for your thoroughness! Your answer of course gives me more questions.
As it was intended.
First, clownfish are not the focus of my tank, I merely wanted a pair bonded behavior to observe. I know your policy on recommending fish, but I still have to give it a shot: Can you mention/recommend another fish that would bond and display interesting paired behavior? You could name a fish and I can go research it myself

I will still check out the book you mentioned.
Well, you can get bonding behavior with firefish, but it is more complex as you must get a M/F and they must bond which does not always happen. You can also get it more easily with a pair of gobies that are bonded along with one or a pair (the pistol shrimp do not have to bond/pair) of pistol shrimp. And, of course a M/F pair of banggai cardinals will bond and mate. I see people wanting clowns but I personally find them to be boring relative to their aggressiveness "cost". It is very, very difficult to recommend. I can relate issues associated with choices, however.
The focus of the tank is actually the pistol/goby pair(s). I even built the stand with an open bottom so I can see the bottom of the tank with a flashlight to watch the pistols activities. I'll stick with a single pair for now, maybe later when I have more experience I'll look into another set. Is 3" of sand overkill for them? Should I go shallower or deeper?
What you need is sand ideally mixed with slightly courser gravel and live rock rubble that can be used for structure. Two to three inches would work well.
Second, what was your concern for the chalk basslet? I only added him to the list because I read that he was 'peaceful' but maybe I'm mixing him up with another fish I read about. Is he going to terrorize someone or compete with a food type or territory?
It is a recollection rather than an experience with them. As I personally keep a Candy Basslet I know that basslets don't really mix so I never kept a chalk basslet. If you are looking for an interesting fish look at the various possum wrasses available (yes I violated my own rule) as I feel they are much more interesting.
This will be my first marine tank, I want to make sure I minimize the noob mistakes as much as possible. :hmm2:
