I have a Xmas tree rock that has several in it, however, they are never out, is this normal? About the only time I can find a couple of them out, is when the lights are off and I look in tank with flashlight. Thanks!
I have 3 fish in the reef tank and I have had the rock about a month. There is more activity when the lights are on during the day. Do the Xmas Tree worms like more or less light? Right now the rock is on the sand and under a 12K metal halide bulb. Thanks! Donna
