Hi I've currently stocked my first aquarium with 6 harlequin Rasbora, however I'm not too sure what tank mates are suitable as I want it to be a community tank with various fish sizes, also I don't want to overload the tank! Preferably I would like barbs or gourami and some bottom feeders, the tank is 70L so I'm under the impression only 12-15 is the maximum?
