Wah Abang Ruslan,

The riccia and the other back ground plants look very healthy too. I guess your theme for your setting is to highlight the riccia as the main plant in your aquarium (correct me if I'm wrong). The riccia provides a good place for fish to lay eggs and the tall plants at the back provide a good place for fries to escape predators or for shy fish couple for "making love". This is a good setting man. Have you achieve any success seen your fish produce new generations?
