Just went and picked up my octopus which I am told is hummelincki. When I got there to pick him up, he was eating a fish which is a good sign considering he had just arrived at the store the night before. He was a red color while eating and then returned to white. When putting him into my tank, i noticed 2 brown spots on him. I took a couple pictures although they did not turn out great. Since adding him to the tank yesterday, he went into the rocks and I have not seen him since.
