UPDATE- DECEMBER 1 2009

Nelly is still going strong (about 8 months old now). She and the Eel are still "best friends". The Baboo was removed from the tank as it became aggressive. The Cuttle and Nelly never bothered each other. The Cuttle died a few months ago after laying eggs for over 2 months continuously. Just added a new baby cuttle to the tank 2 weeks ago. So far so good.

I guess Nelly is now getting old, but she still seems to be going strong (and is very very active all day)

P.S. I have never covered my tank at all and Nelly has never tried to escape. Its been 8 months.
----------------------------------

Hi All,

I have an 600 Litres tank that I started about 8 months ago.

I have an Octo (Octopus aculeatus I think), Cuttle, Ribbon Eel, Snowflake Moray, Large and Small fish and a Bamboo Shark.

I just wanted to share my experiences with everyone.

I got Octo Nelly (my son named her) about a month ago. She has been incredibly friendly and social. She seems to like hanging out (sleeping) with the Ribbon Eel which I found quite strange. She has started feeding by hand a few days ago and I am able to touch her now.

I also have (had) two Cuttles. One died a week ago (and then Nelly ate him) and the other just laid about 20 eggs (big surprise). I guess I bought adults and will have babies soon.

The Snowflake Moray seems to do his own thing as does the shark.

Most interestingly, my tank is not Octo proof (AT ALL). She seems to be perfectly happy not escaping. I put in about 20 shrimp a week and small fish to feed all.

I am hand feeding the eels, Shark and Nelly. They also hunt the shrimp and fish I add.


I am having some water quality issues, but that is another story.

I just wanted to know if anyone else has a similar setup.

I live in Hong Kong and have very easy access to most any species of fish, cephs, etc.

I am quite new at this but have become very interested.

I am glad your tank is working out, I thought cephs were usually kept in Species only tanks even if you have a 160 gallon/600 liter tank. I am shocked that it is working for you and I am happy nothing is getting hurt.

I was scared when I read the title... and now I'm terrified. :alarm: You should NOT, 100% NOT have ANY type of shark in a 160 gallon tank!!!! Let alone all of those animals. It has been well noted that octopuses will eat sharks etc, however aculeatus is most suited to being with other animals. Either way, a SHARK in a 160 gallon tank :banghead:. I hope this is a small shark and that you're planning on upgrading to a VERY large tank soon. Also, two cephs in one tank (apart from cuttlefish) is a no no.

I saw a horrific video on youtube were someone put an Octopus in a tank with a Snowflake Eel I realy hope nothing like that happens to you.
I did not want to link it on here if you want to see it type into youtube Octopus Vs Eel

I agree TDean, that video really just makes my stomach sick. I have seen worse, but really would not want to see that happen to my octopus, let alone any.:mad:

Hi all, just to clarify. The Snowflake is really small as is the Shark (maybe 7inches long) I appreciate all the feedback. At this point everyone seems quite happy together. Octo does not seem to bother anyone (well fed) and the Shark is also very laid back. I will keep everyone posted on how this turns out. I still think it is weird that Octo and the Ribbon sleep together in the same cave most of the time.

My Cuttle will only be around for another week I guess (since she has now laid over 30 eggs). I heard that they die after, correct?

First, please note my personal octopuses are kept in species only tanks and I have no desire to try mixing preditors. That being said, I appreciate members who decide to expeiment as long as they know the eating habits of the critters they mix and post the results even if the mix fails.

We have (or had since we have not seen Dom around for awhile) an experienced reefer who had good luck keeping an octo with a ribbon eel. The bamboo is not likely to hurt the octo (I suspect the opposite is true as well since it is too large for the octo to eat and not a threat - L8_2_Rise - the bamboo is closer to a catfish than the sharks you are thinking of and an aculeatus is nothing like a GPO) but the snowflake may be a problem and likely falls into Thale's "It is OK until it is not" category.

Do you know what kind of cuttles you have? The only ones we see here (US) are the small bendensis and they can mate and lay eggs multiple times over a roughly 18 month lifespan. Most of the larger ones seem to mate, lay eggs and then die within a couple of days. If the eggs hatch in the same tank as your preditor stew, you will not likely see them though as everything you have mentioned will eat the young at the hatching. If you wish to try to raise them, you will need to remove the eggs and read some of the cuttlefish forums on keeping and feeding the new hatched young. If you have a larger species, IT is likely to be a threat to the octopus if it is still eating.

Octohk;138060} My Cuttle will only be around for another week I guess (since she has now laid over 30 eggs). I heard that they die after said:
My cuttle started laying eggs at around 5 months old and lived at least 4 months after she first started laying eggs.

Thanks for the info. My Cuttle is a Bandensis as you suggest. I have collected all the eggs already and put them in a breeder in the main tank for now. If they begin to grow in size I will move them to an isolated tank or larger breeder in the main tank. I have read about rearing them (was just not expecting any eggs at all).

For the Snowflake, I did watch the videos and agree he may become problematic. I need to observe and see.

My theory is that if I keep the tank well stocked with shrimp and small fish no one will bother the others. So far it is working. i add about 15 fish and 20 shrimps a week.
