Depends on what kinda set up you want really. Do you have good light levels?? What kinda substrate yer got etc. There are loads of pinned treads on here telling you what you need to know. Or you could do what I do, all my plants are growing on bog wood, none of my plants in the 55 gal tank are actually planted in the substate. I can then move them about any time I like. I will try n get a piccie for you to see.Mine are all good plants for low light levels
