Hi, I am new to this forum. I bought an octopus about 2 weeks ago. He is alone in a 65gal tank. The salt level is 22 and chiller setpoint maintains water about 76 degrees. I was told he is a Caribbean reef octopus but no scientific name. I have left clams in tank and he has eaten them. He is extremely shy everytime I come in the room he hides as soon as he sees me. I have a red light on tank but he hides while it is on. Is this normal? Water had good test results. Trying to get pic to post to maybe find out species
