they grow well emersed right? the idea i have in mind is having my anubias 1705 (maybe also my nana)stick out of the water as i dont want these huge specimens i just got crowding up the whole tank. but the problem is that they will be getting little light. since i will not have my lights suspended over the tank, i will just have an opening on the tank. 1 light strip sitting over the edge leaves lots of space of opening space. is this possible?
