Very cool tank. And you answered my main question before I even asked, I have a small ric and a small acan garden going in my tank and was wondering about them being being too close together and some even overlapping. But obviously not a real problem based on your tank. Guess they will figure it out for themselves
Are some of your rics on the sand bed or do you have rock under them all. Mine are growing and overhang onto the sand bed but dont seem to be spreading out. Wondering if I should add some flat rock to let them expand?
