I like how you went all out on filtration. I love to have alot of filtration myself. Nothing gets to me as bad as an overstocked tank with poor filtration.
Your plants will look more "real" once they age some and the color fades and get algea on them.
I am sure the barbs wont last long once the O's get big. I had some baby O's and once they got big enough to get the HUGE tiger barbs in thier mouth they slowly pick off the schoal one by one, mostly at night.
Where in Nebraska are you at?
