You'd sell the WK or trade it, of course! Bet it would also look cool in a tall vase with some pool filter sand in the bottom of it.
It could look interesting with Akadama. Small, rimless tanks and light-colored substrates like that look great together for some reason.
Akadama, a nice burl of Malaysian driftwood with lots of hidey holes, moss and such could be stunning. You've got the aesthetic eye so you could definitely make it look better than most.
I definitely don't need more tanks - though I am tempted to buy up tons of these little cubes - so I have to live vicariously through this journal.
