The pond we are considering adding either GSH or even shad if we could source them has what I believe to be a type of water lily I will take some pics next time we are there and post here.

Would the lilies be good for the GSH or shad or do they need something else more like cedars, pondweed, water primrose etc.?

Would it wise to add some sort of vegetation and if so can you give me some ideas as to what I could add and what I should avoid at all costs?

Thanks
