Technically you don't need fertilizer, but if you want your plants to grow you should grab some. There are a number of fertilizers available at Petsmart/Petco. I personally use Tetra's FloraPride which seems to work but there are many others to choose from that are probably better (I haven't really experimented). Dose it according to the instructions on the bottle :)
