The first forum I would like to recommend reading for, "how to" is Octopus Care
. Pay special attention to the Sticky Posts in blue at the top of the page. I suggest reading the posts in Posts with Info for New Octo Keepers to start
(it includes suggestions for tank cycling and set up. The link is part of whole forum, Tank Talk
, dedicated to tank environments.
For fun reading and vicarious keeping experience, read through some of our journals. The current most active will be @sedna
