Ive been seeing some pretty cool cold water octopus tanks here and I'm trying to get some more info on the whole thing.
Is coldwater the same principle as regular salt, just cold? Does it follow the same cycle?
Coldwater tanks will take much longer to cycle, treat it more along the lines of a fish only tropical marine tank as far as filtration. Make sure and get a quality chiller, or at least one you trust, since that will be the heart of your system.
Also, what size tank would I need for the octo.
Size depends on species. An E. Dofleini can get 20 feet across and 160 lbs, where as an O. Rubescens maxes out around 24 inches and 6 pounds.
Where can I get one online?
You can purchase them from me
I will be licensed and permitted to collect and sell marine fish and invertebrates from the state of Oregon as of January 1st 2012. PM me for more details
Is he best left alone, or is there things I can put in with him? How can I octopus proof the tank. What do they eat?
Anything you put in there with him is a potential food target that is a fish or invert. They wont mess with anemones and corals really but larger anemones may damage your octopus. I have several slipper cucumbers and small patches of corynactis in with mine, as well as lots of live shrimp (which he seems to ignore) and lots of shore crabs which is his food source.
As for octopus proofing it, best rule of thumb is that if their eye can fit through so can they. ( People always say their beak, but how many times are you going to see that really?) Make sure and make a good lock down top.
Is there any good guides I can read? (read the sticky up top, that said articles, wasn't sure if it would actually be a guide)
Thanks and all help is appreciated.
