Hi Chris,
my suggestion would be to go to the fish profile page of Fishlore and start going through the list checking out the photos and requirements of fish that may interest you. There are so many fish to pick from the list there. You mentioned you didnt want cichlids and you dont want the mollies, platy guppies etc etc. I would also advise that you check the
pH requirements of the fish as well as compatible water temperature needs.
If you can round up a group of fish you may like to add to your tank you can come back to this post with the list and other members can let you know their opinion on the list.
You can look at my aquarium siggie below to see what I have in my 55g tank.
