Well, I had an octopus many years ago and he did quite well, unfortuneatly he decide he wanted to get inside a powerhead. Currently I have a very successful reef tank and now an octopus tank as well. I was at a local pet store when I saw my octopus in a small plastic container, inside of a larger tank. The octo had nowhere to hide at all and they had put it under full lighting. Then I noticed that two if its legs had also been damaged and were basically cut in half. I decided to save the poor thing. This was 2 weeks ago, he is now doing great in his own tank with plently of live rock to hide in. I have 5 questions for you guys. 1) Is it possible for its legs to grow back? or not? 2) What kind of lighting cycle does it need? Currently a moonlight comes on at 8am untill noon where a flourescent light comes on till about 4, then a moonlight till 10 then darkness. 3) The octo is currently eating ghost shrimp, I have attempted frozen twice, but no luck. Any suggestions on diet? 4) I can't tell what type of octopus it is and they didn't know at the pet store. I see no blue rings, so I don't think its a blue ring. it's body is only about half an inch and it alternates colors from light brown to redish brown. 5) I have noticed sometimes it looks like it is breathing very heavily, could this be a problem? I was devistated when captain (my last octopus) died, so I am really hoping to do my best for this one. He is adorable and the best part is I'm pretty sure he has taken a shine to me, when I'm alone on the room he comes out of hiding and watches me, but if anyone else comes in he hides. Thank you all for your help.
