We have clowns, a wrasse, an angel, two gobies, and discovered a rogue octopus had come in a rock. It was small and we tried so hard to capture it during the nights because we were afraid it would eat the gobies and it was stressing the clowns. Unfortunately, it died and inked the tank, making the coral and fish sick. We are doing water changes and hoping to save everything. I would not recommend it. They are nocturnal and come out at night.
