I recently purchased and octopus from live aquaria. It was said to be a Mexico octopus. Unfortunately I didn't take any pics before I put him in the tank which is gunna be 2 weeks ago coming up this Saturday. I have really only seen him out once at night and every now and then I will seen a tentacle pop out for where he made his den. He has eaten the emerald crabs that I put in there and I think one hermit crab. Does anyone know if or when he will come out of hiding I tried getting him to come out by putting some frozen shrimp in front of his den but only got a tentacle And wasn't interested. How can I get him to come out ?
