I got 2 LTA's yesterday. I put one in and it is at the bottom of my tank on the sand by a rock. The secon is on a rock up higher. I thought they need to be in the sand so I tried to move the second one today however it is attached to the rock. I noticed the first one kind of folded up once the lights went out and today it opened a little. The second one didn't seem to change when the lights went out and the tenticles don't seem to be moving much today. I have read that they take longer to get use to the tank and I have read that they usually move around the aquarium however neither of mine have moved. Should I be concerned or just be patient?
