I'm going to set-up a 37 gal for a bimac. I'm going to drill 2 holes in it for the sump drian and return line. I don't have my lid planed out yet, it all depends on if I break the tank while drilling. But I have a few questions. Should i have a DSB with a bimac-octo? If I have a DBS, should I provide PVC tunnels for the Octo to crawl through, or will I never see it? Do they only eat live food? Is there any good octo books available? What is the best lighting set-up? Any other toys that I should look into for keeping it busy? Thanks.
