I am planning on seting up a 20l, will one florsent bulb the length of tank work well? If not, what is the recommend watage for PC bulbs? I am going to set the tank up with gravel on the bottom, then some bed-a-beast, and then moss. I plan on live plants and a water dish and coconut hiding spots. Is there any thing else I am forgeting? Any tips? Thanks, Jacob.
