I have a 110g tank, running for about two months. The tank currently has 100lbs of sand(a little over an inch of substrate) and 30lbs. of live rock, with another 90lbs in a separate tank curing. I have a sump rated for a larger tank, and also an extra canister filter rated for a 100g. I'll be picking up a protein skimmer later this week and adding it into the mix. So now the question is...What species? I would prefer a diurnal octopus but I know you cant be to picky since its already hard to find any octopi. My tank stays around 74-76 degrees and can be lit either by a fake light, or natural sunlight as its near a window that currently is shut so it doesn't allow light in. Id prefer a larger species but I don't want anything that wouldn't be fully comfortable within the tank. I'm not planning on picking an octo up till late march but wanted to go ahead and try and find a species and seller =] Any recommendations on the species or tweaks to make to the tank please let me know thanks =].
