I found this activity going on in the reef tank early this morning.
The sea cucumber has been consistently "vacuuming" the sand with its sticky tentacles when the lights go out. It has also grown in size over the past several months. This is the same sea cucumber I inherited with my tank "upgrade". After I initially set up the tank, the sea cucumber would invariably crawl up the side of the tank during the night and end up going over the overflow and landing in the sump. Because it has decided to stay in the main tank now, I consider this as a stamp of approval on the tank's condition.
Before it crawls back to a dark cave for the day, here it is posing with the slowly recovering "x-mas" Favia coral.
