Nice tank, I like your lay-out and am curious how its developed. How's it looking now? I'm particularly curious how the Bolbitis looks. I'm interested since a number of people, myself included, believe that there are two different forms of B. heudolti that are commonly circulating within the aquarium trade. One has much lengthier fronds, which I believe is the original B. heudolti that was introduced to the aquarium trade a long time ago, but nowadays there appears to be a form that stays lower and develops shorter, bushier fronds. I used to believe that this was likely due to differences in water parameters, and aquarium conditions, (lighting, fertilization, level of co2 injection if any, and the plants positioning in the tank in relation to the flow of the water), but I now believe that the two different kinds may have to do with a slight genetic variation, possibly due to differences in collection location of wild plants.
