Looking for neat or unconventional fish stocking ideas!!!

[ScubaSteve]

Hey Fish People!

I need some help. I need some suggestions on fish stocking in my 50 gallon cube. I am running open top, so that's my main concern. I'm also making this primarily a coral tank, so I don't need a huge fish list but...

I'm looking for some cool ideas! I'm more of a coral guy, so I tend to draw blanks when it comes to my fish wishlist. I'm really serious when I say: no clownfish, no damsels, no cardinals. This will be an SPS and zoa tank, so the fish need to be safe for those two especially. I am all for challenging fish and am ready to try unconventional ideas (in fact I would like to challenge conventional thought). This whole tank is, in some ways, an experiment in what can be done.

Feel free to make all suggestions, this is an open forum. (INSERT FISH HERE)-Police, please stay your piece. I am aware of all the ethical issues, I know what can be done with what fish, I've been lambasted before, I get it. Please, allow people to make suggestions without fear of reprisal or flaming.

I've so far been considering anthias; either Bartlett's or Sunset Anthias. They're a bit more than what I'd like to throw down on fish for the time being but I have been tossing around designing the flow patterns to simulate a reef crest and choose a dominant fish (different species) that hangs out below. I've been studying anthias behaviour for a while and chatting with a few fish specialists on how to keep anthias in a small school without them all killing each other or all turning male (and subsequently killing each other); starting to have a pretty solid theory I want to try out... but alas, I be poor.

So, any suggestions on some other fish that are cool? Pairs?

I'm all ears!
