Getting ready to move to bigger tank, got any tips?

[jojabis]

Currently my T. Maxima is attached to a rock 8" deep in a 20L (30 x 12 x 12) about 15" from 150wt HQI. The new tank is 90 gal (48 x 21 x 18) will get 4 of the 150s over it. Can I leave the clam attached to it's rock? Or do I have to remove it, I would rather leave it attached.

tia,
