Hi, glad you have found a good source of information. How long have you owned a Vulgaris? What size tank? What kind of filtration? Where did you buy it? Enquiring minds want to know
Much of the same information you will find in the Ceph Care articles as well as the forums applies to babies as well, you will just need to provide much smaller live food for them; hermits, snails, mysis shrimp, etc. And being smaller, they will be more capable of escaping through even the most seemingly unlikely of spots, so make sure there's nowhere for them to get sucked into a pump.
If you own a Vulgaris, you should be aware that feeding an octopus is expensive, especially more so when they won't accept thawed raw foods like shrimp and silversides, and the larger they grow, the larger their appetite is going to be. If you live near the beach in California, feeding them will probably not be that big of an issue.
For now though, you should read all of the articles on this website, even the ones pertaining to Cuttlefish husbandry, as the more knowlegde you take in now, the better off you will be when you come across changes in behavior, husbandry do's and don'ts, and everything else involved with this particular hobby. Both you and your pet will be better off!
Also, if you don't have a tank set up for another octopus yet, you should focus on your Vulgaris while you get the other tank put together and cycling. You need to wait AT LEAST 3 months for the tank to fully cycle before buying an octopus for it. Many people aren't patient enough to wait out this long, and most of the time it ends with the octopus' premature death.
