I need some more plants for my tank. Aiming for low-medium light, and able to be run over by a mystery snail and not easily uprooted. Emphasis on that part. Soooo many plants float because Mr. Mystery tramples over them or the filter blows on them. My current plants that are doing well, to give an idea: Amazon swords Purple cabomba Rosette sword Parrot's feather Anubias Java ferns Bacopa Susswassertang Java moss Some sort of grass-like sword (forgot the name) Thanks.
