Other good house hold plants for aquarium are ivys, spider plants and hostas. I think almost home have some sort of ivys. Ivys are shady plants, I wouldn't recommend it if your tank is next to a window. Just take a cutting and submerge it in your tank and tied the stem to the side. It will grow. Another good alternative is to have a 5-10 gallon pot.
This is good if you want the "Black Magic" taro, since this plant gets quite large. Also good for water chesnut.
