What to do with my biocube 16....

[jjschno]

So I have had a larger main display and my little biocube, the biocube gets no love and doesn't even have inhabitants, its just rock sand and water. So I was wondering what you all think I should do, my plan is to attach it to my main display as a joint piece, but what should it be? The main display is a waterbox 105.4 frag, around 70-80ish display with a 20 or so gallon sump for anyone wondering.

Why not do something a little out-in-left-field, like a sea of Pulsing Xenia (only) tank— with one Yellow Tail Damsel as king.
