While I do enjoy looking at my tank, I feel as if it is lacking some more color? Everything is very green! only thing that has a slight hint of red is my Rotala Indica. Anyone have any suggestion for plant species with more color? tank is an 8 gallon & the footprint is kind of cubeish. No special substrate just sand, c02 via reactor, seachem comprehensive, 1 15watt 6500cfl & one 13 watt cfl 6500
