Placement for a Classic Red/Blue Rim Acan

[Merry]

I just this past week purchased a classic red/blue rim Acan for my BioCube 312 with the stock lighting. I have no interest in fragging later. It is very small on a peg and I placed it on the sandbed. Should I keep it there or move it to a rock? If I place it on the rock do I leave it on the disc removing the peg?

Sandbed or low on your rockwork. Low light and low to moderate flow is preferred for these guys
