I've never kept a ceph before. However, I do have two reef tanks, a seahorse tank, and a moon jelly tank. I need some help getting started. I live in the US, so I believe it's a little harder to get a hold of a cephelopod. What kind of octopus or cuttlefish (that can be bought in America) can I keep in a 30-40 gallon aquarium? And are there any articles for these species? Also, where would I buy it? What species did you start with and what do you suggest I should start with? Any help would be great! Thanks!
