I have a 90g tank, it's been up & running for exactly one year as off last week. I had a octopus bimaculoides in the begging but sadly it passed away months ago, know I had a 1/10 hp chiller keeping the water at 72° Fahrenheit when I had the octo. But living in southern California which is always hot and no air conditioning or insulation in my bedroom meant the chill was always running, blowing hot air and making noise while I slept. My question is, what octopus would you guys recommend for a 90g but that is a tropical species so my chiller isn't running 24/7 and is diurnal?
