lol kanga, mike might be a slight draw back but he does know of some really decent tanks in the area and a few darn fine LFS, but he does drink as much beer as you do
Tankgirl fish compatability is a great topic and endless fun in my view. a few clowns generally will cohabit with most other fish so long as they are suited to a smaller tank like a nano. However some clowns can be real terratorial (tomatoe clowns jump to mind) so even there you have to research, but thats fun anyway
the way i go about it is to pm a guru.....no kidding thats what most people do, the best way is to choose a fish you like the look of and :googlenub: from as many marine sites as you can. the ask people on MASA what their experience of a specific fish is, thats when you find out all the true specifics of a specific fish that the general lists dont tell ya.
have a good look through some of the members sections as to what they have achieved( we have some stunning tanks in MASA) and especially the nano's so that you have a goal tank to work towards. then with that as a guidline you'll better visualise what your end tank will be like
