i'm still working out a budget and components list for a (possible) octopus tank and i am having a hard time finding information about lighting requirements. In a couple of the articles by Nancy and Colin it is mentioned that octopuses don't really have lighting standards, and i remember that they need red, not normal actinic lights for night-time, but i am wondering how you guys individually have tackled lighting? is 30 watts over a 50 gal tank really sufficient? can an environment be too bright for an octopus? how much is too much? are LEDs ok? so please post what you use and any general info. i didnt see anything like this in other threads. if it's already been covered i'll gladly delete this post.
