Careful with discus if you aren't prepared to do a lot of water changes and if you water is too hard, don't expect them to breed successfully. Also, if you are growing them out from juvenile size, always go bare bottom, it'll help ensure that you keep things clean for them so that they grow correctly. Discus are more easily stunted/deformed than a lot of other fish, IMO, if you aren't staying on top of everything.
