I have been wondering if anyone has ideas about how much light newly hatched octos need? I have been reading that fish fry have to have the tank sides blacked out and only lit from above so they can see their prey. Sounds good, however octos aren't fish, so I was wondering of the same rule applies? My tanks are near a window that receives a strong southern exposure, I was thinking of just setting up my hatch out tank in the same place and only giving them the natural light. I have extra lights, so I could try either method...

You probably already know this but, the reason for blacking the sides of the tanks for larval fish is because their vision is not fully developed. The black background makes it easier for them to determine the distance their food is from them. I don't know if there is a similar vision development delay issue for octos. Cuttles don't seem to have that issue: http://news.bbc.co.uk/2/hi/science/nature/7435757.stm
