Man, toy have some nice clams! I really like that small maxima (baby blue, black and gold) and the fine lined derasa is awesome!... And those green croceas.... And, and...
I run my tank bare bottom because of flow too. I did not like it at first, but now it's grown on me.
Also, if you ever get the dreadful pyramid snails, a sand bed makes them extremely hard to eradicate with a sand bed.
I would highly recommended a few Macropharyngodon sp wrasses (aka leopard wrasses) for these snails, as a preventative measure. They do require a sand bed to bury in a night or when startled.
wow great idea, i never liked the zero edge tanks beacuse you had to clean both sides of the glass but with this desig n it makes me want to build my own!!
I think one of the big tank manufacturers are going to steal this idea
