i can get you tons of parrot feather in june when it starts to grow locally. it doesnt do well submerged and prefers being mostly out of the water. this is why it is more suited for ponds. it did well in my 125 and is on the thread in the beginning but i just didnt like the way it looked. now i have some in a vase on the window sil. it grows much better emersed with snails in the vase feeding them.
