As for fish suggestions, read up on various fishes and figure out which fish hold the most interest for you. Visit a few fish shops and see the fish in tanks to see what they look like and off course read up on the maintenance a fish would require and whether you have the time and interest for a high maintenance tank or would prefer a low maintenance tank.
Simply put everyone likes different fishes and its best you get a fish you like than a "beautiful and active" fish that you get bored of quickly.
