I have a 20g long tank that I am planting. I currently have 5 glowlight tetras and two bolivian rams. The rams are male and female (I think). I have an Aqueon T5NO dual fixture that I am returning today. I am getting a fishneedit T5HO dual fixture instead. I have a val plant in there right now. I also have two large pieces of driftwood that are currently in the process of soaking. I will order the new light today, and update frequently.
