I picked up an 8 legger from Ed. His name is SUCKA! He's in a small tank until I can get a good enough picture to id what type of octo it is. Currently I am feeding it sally lightfoot crabs. It is AWESOME to watch him crack open the shells and eat their brains. Then he tries to drag them into his rock, but they are too big to fit through the holes from which he comes out of. He is definitely nocturnal, and swims around the tank at night. With subdued lighting I can watch him from far. His feedings are expensive, but so far, very much worth it!
