Live small aquarium plants (Montgomery)

I just put the last two goldfish into my pond & aqua plants need fish to survive. These are aquarium plants not pond plants, so they need a new home where they can live with fish & a light source. There are 4 all pretty small, currently in a 15 gallon tank. One is in a basket, others are anchored in the gravel. If you have everything they need to strive plz let me know. Thanks
