It turns out they do make a moonlight for the baby biorb. I even found a website that is selling the tank and moonlight together.
Hmm
I'd feel guilty setting up a tacky tank on purpose. All of my tanks are planted, and I guess look pretty natural. I think my fish in the natural tanks would taunt and pick on the fish in the tacky tank, thus making them angry.. Then the tacky tank inhabitants would plot to get me in my sleep or something.. and I dot want to go to bed worrying about that...
