At the top of the home page, right under the Tonmo logo there is a gray bar with the word articles. Click on that , and the first several Articles listed are all under the general heading of ceph care. Read those articles and you will start to get a better understanding about what is involved in keeping a ceph. It is strongly recommended that you do not start with an octopus or a cuttlefish, because they are much more difficult than most other aquarium animals. They are also very expensive to keep, and unless you have very generous parents, it's probably a good idea to wait until you can afford to feed them what they need. Many cephs will only eat live food and that can get to be extremely expensive. Please read those articles, and if you have more questions after that, there are knowledgeable people here who will be able to answer your specific questions.
