Not a pair. Only ever keep them in trios (1 male, 2 females) if you want them to last Also, don't attempt a trio in a 10 gallon.
A single male would be fine. You can keep some pygmy cories and dwarf rasboras with him or some guppies or endler's or you can have a trio of platies. Take a look here: http/www.fishforums.net/index.php?showto...=options+gallon I wrote that a while ago - it has all sorts of 10 gallon options.
