i had the same setup you had a while back. the male never quit bugging the female, i ended up with fry, so i dont think there is much to worry about(unless you dont want fry
). i added a blue gourami and an opaline gourami, but there is a veriety of fish you can add. just dont overstock. i picked this up in a good FW fish book.
w x l = total surface area, 1 inch of fish = 12 sq. inches surface area.
if your tank is the same as mine(most 10 gallon tanks are) it should be 20 x 10, total 200 square inches of fishy goodness to play with. hope it helps! :D
