When presented with a fantastic catalogue of coloured pictures and photographs of plants it is easy to become carried away with the huge choice available and to end up with a somewhat cluttered look in the tank.
This may be very effective in a 'jungle' style aquascape but in many other styles, such as the simpler Iwagumi layout, a cleaner less cluttered style of planting works very well indeed.
Obviously certain plants gel well together, and different patterns, textures and colours may be represented in the aquarium just as they are in nature.
