Normal for RBTA to hide?

[jquek]

Hi,

Is it normal behaviour for RBTA to hide in/under/behind the LRs even after about 1 and a half week in the tank? It sometimes also moves to hide behind the LRs and shrivelled up though its still attached to the rock. It opens occasionally (not fully i think) but at the same time hides very much too. Tried to feed it (without success) but when approached, it will close up almost immediately. Are these normal behaviour or is there something it doesn't like in the tank? I do think its still healthy since it still attaches to the rock and is responsive but it just doesn't like opening up and enjoy the light?? By the way, the anemone is positioned near the sandbed of a 2 ft ht tank. Any advice?

Tank/water parameters: 150W 14K Mh light; NH3=0; NO2=0; NO3=30-40ppm; PO4=0; PH~8.0-8.1; sg=1.023; Ca>400; Alk=7.7dkh; temp=26-28C
