Yea mine was at the top of my tank, about 6 inches from the 175 watt 10k halide and 2 55wat pcs. But found he was gapping.. he had attached to the rock though,  
 
 so i moved him down to the bottom of the tank about 18 inches from the halide now, seems to still be attached.. and not gapping as much.. so i will give himsome time and see if he is happier here or not.
