What are some low light and hardy plants that I can use to cover my aquarium floor with? I'm planning to keep angelfish, maybe a pleco/cory catfish, and some random compatible fish depending on what fish stores have in stock 
I'm buying a used tank that comes with 2 of those marineland penguin filters(for up to 150 gallons combined), so would that allow me to overcrowd a little bit?

Edit:Since angels get pretty tall in height, are there caves for sale that can fit angels?
