That's an impossible question as what I would suggest may not be what you like.
I personally would decide what sort of fish you would like to keep
1) You could have a species tank (african cichlids, livebearers etc....)
2) Do you want small shoals of tetra or two or three larger fish?
3) Are you after oddballs or regular type fish?
Look at some of the pictures in the gallery, take a look at your LFS, do a bit of research as you'll never find someone with exactly the same taste as you but you can certainly gleam ideas from many sources, put them together and you've got your own community!!!!
Definately ask questions on the sorts of fish you want, but try to get an idea first, get a list and find out if they're compatable, if they're not, then choose something else!!!!!!
Good luck with your decisions!
