I have a 20G tank empty for a long long time. So started playing with couple of rocks collected locally and some gravels. And I have came out with this scape. what you think about it?? Suggestion and criticism most welcome. Also help me to choose plants for this scape. Thought about HC but not confident enough that I ill be able to grow them. So what plant should go for the foreground? Also what in Mid and Background? Will use Amazonia II with pressurized CO2 and 5 WPG PLL 6500K light.
