Royal Gramma's

[supersmile]

We just bought a Royal Gramma on Friday. When we got it he darted right into the live rock and hid. At times we would see his head poking out but he never did come out not even at dinner time! Yesterday we tried moving the rock we thought he was hiding in to get him to come out and he wasn't there. Now we don't know where he is. Is it normal for this fish to still be hiding and never come out after we have had him for 4 days already??? I didn't buy this fish for him to always hide and never see it!
