hello i have one of these in my aquarium but mine only lies down with his foot out . when i brought him from the store he was standing upright, how much substrate do you have in your aquarium and how can i get mine to stand. and does it matter on the grade of sand ?
Just a couple of hours.... when the lights come on in the tank the sea pen begins to emerge ... within about two hours he's wide awake. When the lights go off he goes back under the sand... it's wild...

This is great! I studied this behaviour in sea pens for several years but never thought of putting it to a soundtrack!
