I am considering setting up a community tank in a 40 breeder- either with one male betta and some peaceful schooling or shoaling fish or else with 2 male bettas (separated by an opaque divider) and smaller groups of schooling or shoaling fish- and was wondering what species of schooling or shoaling fish would work. If it helps, I intend to plant the tank fairly heavily. Also, you should know that I have no experience with freshwater aquaria, though I do have a few years of experience keeping Dwarf Seahorses. So beginner fish are preferrable, although given my experience with finicky Dwarf seahorses, I may be able to handle some intermediate level fish.
tl;dr What beginner level fish are suitable for a 40 breeder (which may or may not be divided in half) with one (or possibly two) male betta fish?
