Agree with anubias, Val, swords (though they don't seem to always do well in my low tech tank), crypt wendtiI has done really well for me...

Well, You’ve gotten some good plant suggestions. Vals, java fern, anubias, swords and crypts. I agree with them all. What kind of substrate do you have? Do you plan on dosing ferts? If you do, you can do some stem plants like bacopa monnerI and carolinana, some ludwigia, anacharis, most hygrophilia. Id do taller plants for a 40gal is it a 40 breeder? Try plants like jungle val, hygrophilia difformis, crytpt wendtiI bronze or green, bacopa monnerI and an amazon sword.
