New to octopus tanks


Aug 8, 2019
Hello so I am interested in starting an octopus tank. I wanted to know what size I should get I am thinking about getting an O. Vulgaris. Also what I might need and where to get an octopus. I am open to looking into other octopus but just need help with finding one and all I need. Any advice for a first time owner? I live in Los Angeles, California and want to start one ASAP! If anyone can help me with filters and what else to get it would be greatly appreciated thank you!

I trust we'll have some of our resident experts weigh in, but a few things I think are correct:
- vulgaris grow fairly large for a home tank; I think I recall recommendations for at least 75 gallons
- I also understand they are typically nocturnal. If you are a night sleeper, you and your octo buddy may be more estranged than either of you might like.
- you sound like you are in a hurry for this; generally this not a good sign, but if I'm reading you correctly, you just want to get the tank going quickly, not necessarily rush the octo. But just in case šŸ˜ -- we have found that haste breeds failure; this is a pretty painstaking hobby (which is why I don't do it). Keep in mind it can take months to properly cycle your tank before it's ready for a ceph. I don't mean to discourage you from it, but I do mean to encourage you to reflect on this, adapt your plan accordingly, or shelve it for a better time for you if it comes to that!
