Nemo has adopted this lump of mat covering one of the wrought iron curly cues of his basking lamp table. He seems to love resting his chin on lumps of blankets. This is the first really good look I had at seeing how he stretches his head out to rest it on a "pillow" of blanket or rug. Doesn't he look so peaceful?
I still think it is odd that he will curl up in as much of a circle as he can like a cat to sleep. My assumption would have been that turtles would pull into their shells to sleep. Guess he wants to see what's going on.
