You should add a red specie of plant as the center piece.
I would like to but I don't think my lighting is strong enough to sustain one. The plants in the front (Lobelia cardinalis) were actually partially red when I planted them....due to the lack of sufficient lighting they all turned green. Are there any red plants that don't need high intensity lighting?
It looks really nice! I agree that a dwarf Tiger Lotus would be a nice addition, maybe in the little cove created by the stump on the right side of the tank? The extra lobelia there could be moved to the far left side.
Really love it, but if I had to change something, I would add something like Flame Moss to the piece of wood. I would also add more of a diversity of plants. You should try cryptocoryne species and something slightly red like Rotala Indica. I think that would make your tank "pop". But, really it's fine as it is.
Really good looking tank. Love the plants. I had a 16G bowfront, but have upgraded to a 20G High. What's your opinion on the bowfront?
Actually I am on the fence regarding the bowfront. I custom built the canopy which ended up being more difficult then it should have been due to the curve. It is also much harder to fit multiple lighting units due to the bow. That being said, I think they look good when everything is finally set up. I had a smaller cylinder tank that I absolutely hated due to the viewing distortion. I was worried about that with the bowfront but it is pretty clear looking through the front.
