Are these mini-lotus or big lotus?? Can you keep plants in your pond with your fish?? My koi are kinda wild and pull up and eat all plants they can get hold of!

Those are the big boys.
I'll pot them and put gravel then larger rocks ontop of the soil. That's what I do with my lillies. Most of my fish are Comets. I only have 3 Koi (12", 10", and 5")
