If you aquascape the tank from the beginning with a lay-out, you should be able to get whatever look you are trying to achieve. Browse through pics of other users aquariums for examples. The only reason for potting them would be for easy moving or if you have perhaps diggers or something of the sort. If you just want the pots period, well, burying them is fine or hiding them some sort of way with rocks, wood etc may be okay too. IMO- I would plant them without the pots
