Do you see lots of life in it when you take the time to look? My only worry about them at all is that somehow I won't end up with enough life to 'work it' for me...
To be honest with you, there are pods in the fuge, the sand bed has worms, and life is good. I honestly haven't taken a real good look in there for about 3-4 months. I have plenty of pod life in there and in the display.
