Welcome,
Sounds like you are going about this the right way. So many people want to jump in and end up getting frustrated and killing something.
I have herps too. I would equate cephs to poison dart frogs or chameleon species. Short lived, suseptible to environmental conditions, and you don't know they are sick until they are really sick or just die. BUT.... just like the dendrobates azureus and chameleo pardalis -nothing is cooler. Part of the satisfaction to me is knowing I have the knowledge to properly care for these animals, but it takes time.
Scour the articles on this site. They are the best I have ever seen in one place. I had octos 15 years ago and was flying by the seat of my pants. It was very frustrating and definately a learning experience.
Another good resource is "the cephalopod page" by James Wood.

Ask lots of questions on these forums too. Everyone here has different ways that they do it-so you may not get the same answer, but they all will work.
Happy Herping and Cephing!
