You have very little light for that size tank. I've never have good luck with swords in low light <40Wx2>. <No luck in medium either....> You would need to triple your light to consider swords IMO. <FYI, I have 4x that amount over my tank & is only good for medium light plants.> Anubias, however, would do just fine with what you got.
With the amount of light, you prob don't need to dose fert. Esp. when you hae goldies, they make enough waste as is. <Also swords would do better with root ferts (tabs or substrate) ... but that is a moot point when you don't have enough light.>
