Hi Tonmo

We are two college students who have been lurking on this community for some time as we made preparation to get ourselves an octopus. We followed all the suggestions and have set up a good quality 90 gallon. A month and a half ago we purchased the octo from saltwaterfish, and have since hit an issue.

Our octo has not left its den (to our knowledge) in the entire time that we've had it. We realized a while back that this was due to our blue LED lighting, which must've been too bright for it, and so switched to red LED. All other conditions are optimal. However, it still refuses to come out at all. The live fiddlers we offer have stopped disappearing, so we began feeding it ourselves by offering shrimp on a bamboo skewer every day. It reaches out, three tentacles max at a time, probes at it, but doesnt seem to take any. It does this several times until it eventually stops pulling at it and instead swats it away.

We are concerned about this behavior and are looking for ways to coax it out and get it eating more. Please let us know your suggestions and if you've ever had experience with an octopus this shy/scared for this long. How should we proceed? We will be updating this journal as we go, but of course we have no photos yet, as all we've seen since putting it in is a few tentacles sticking out of a rock, hence its name.

Hello! Welcome to the neighborhood!

How long did the tank and live rock cycle?
Have you checked the water/salt/ammonia/nitrates levels?
Water temp?
Any photos of your set up and tank?
Any photos of your ceph?

If you made it past your first couple of weeks... for the first month or 3, if it is young, you're lucky to see the ceph much.

Have you tried a teeny piece of shrimp on a long stick where it (name?) hides?
Don't tug of war, resist the urge.
Teeny, like, peace sized, a small pea.

You can ways try another piece, let it refuse.

Maybe the fiddlers are too big yet. You can try hermits, small ones. Sometimes octos will eat them OR at least attack or hug them and lug them around.

Little things in the tank, like shells, can entice your ceph to build a door. It's a good tricky to figure out if your ceph is out and about.

Try to keep positive. If you've been reading along in the threads, sometimes you end up with a traumatized ceph, or a sick ceph, or a super hidey ceph. Feed it, love it, get it little things to build or play with, and it might come out after a while.

Octopus pets often try our patience. One way or another.

Ps you don't have fish in the tank... Correct? Take them out if you do.
I learned my lesson withat that.

No fish in the tank, all water conditions optimal and confirmed regularly by test kit, and we had a cycling period of more than two months. The only thing is that temp has been rather high lately due to these intense two weeks. We've managed to cool the water down by putting in large RO/DI ice cubes every day.

Our octopus (Rocktopus; named so because from our perspective, it is merely a rock that occasionally waves tentacles) had built a door earlier, apparently using a piece of rock it broke off. It has since removed the door and doesn't use one any more, but had the materials to make one if it needs. We have tried hermits from very small to fiddler size. Whenever they crawl near its den, it grabs them and flings them away.
We have been feeding it shrimp exactly as you describe. The other night it managed to break off a tiny piece, swung it around a bit, and then simply dropped it on the ground.

We'd love to hear suggestions on encouraging it to come out. Our primary concern is making sure it is eating well and staying healthy, but never getting to see it and struggling to feed it every night is a poor return on investment.

How long have you had Rocktopus?

When Taba, my first ceph, starting pushing food away, we tried feeding every other day.

Did this for a couple of weeks, it again started to refuse food, then it died.

There are too many stories of short lived cephs. Do not let it discourage you. Ordering an octopus is like a box of chocolates.

Our 2nd Octopus stole the show, and our hearts. Misty lived for months and gave us and many others, a great tank to watch.

Rocktopus plays with the shrimp for a bit, pulls it toward the den and we offer no resistance. It will do this for 40 minutes to an hour, not visibly taking any pieces, and then begin pushing it away at some point.

Any other foods we could try that might be more appetizing?

Maybe have the shrimp piece be very loose on the stick. Maybe it doesn't get food must be pulled off. Maybe.

Try fresh clam.

Enjoy the look the seafood counter guy gives you when you ask for just one, lol.

Let the clam sit in cool water, rinse the muck off, let it filter a little, and stick your knife in it to open the shell for the octopus. I scrape it and cut into it a bit to make it easier to grab and take.
Can also try pieces of it on a stick.

@Jocco has covered most of the suggestions I might offer except the possibility that you have a brooding female (either with eggs in your aquarium or having laid eggs before she was caught, a senescent male is more likely to be very active while not eating). It may be eating small crustaceans in the tank (amphipods) but it is not normal for an animal that WAS eating small crabs (fiddlers) to stop unless it is brooding and/or in senescence. Since it is not maintaining a door, there may not be eggs but the symptoms are common to brooding and a female will continue to brood if removed from her eggs.

Do you remember anything about the size or other features when it arrived (best guess is best you can do for this one but in the future, I highly recommend photographing during acclimation). Size, however, is not much help after a point as they all vary significantly. A female with ripe eggs can sometimes be spotted from the distended and somewhat floppy mantle. However, I find this easier to note when I have observed the animal for a month or more.

Our primary concern is making sure it is eating well and staying healthy, but never getting to see it and struggling to feed it every night is a poor return on investment.
LOL, There is NO good ROI in this hobby (saltwater aquariums in general but this is true of most hobbies). Octopuses, in particular, are short lived (8-18 months for the species kept at home and you don't know the age when they arrive). I always advise setting up a tank that can accommodate any of the most common species (which you seem to have done) because of the short lifespan. That being said, I hope you are not too discouraged with your first animal.

I was getting to brooding, DW.

Sad, but part of the cycle of their life, and keeping these wonderful creatures.

I do hope they try again! Although an investment, it's priceless when you get an active, quirky octopus lol!


I'm also wondering how long they've had the ceph, see if it's from the same area mine came from. If there is a species popular this time of year etc. Help them ID, help me ID. Further the amazing amount of info in this forum.
