Hello All,

I am fairly new to all of this so please bare with me if my terminology in incorrect. My Indo-Pacific Red Octopus just laid a bunch of egg sacs. What do I do?

Sincerely, Giar

What size eggs, are they the size of a Pea or a grain of rice? Do you have pictures of the octopus? Indo Pacific makes me think its an Adopus.

... but red makes me think Macropus. Unfortunately, either way they would be small eggs (there may be a couple in the Macropus complex that are not but the comment was not clear on the specific species and for sure (ie thought to be).

That be said, the drill goes like this:

- IF the animal was captured not more than 4 months ago, the eggs may well be fertile. Watch for two black dot on the eggs in a week or two. The small eggs seem to hatch much more quickly than the large egg and can hatch in as little as two week (8-10 weeks seems to be normal for the larger egg species where 2-6 weeks is what we see for the small egg). Tank temperature has been shown to impact time of hatching.

- Unfortunately, if it is a small egg species, you are pretty much out of luck if you would like to try to raise a couple. Even the large, ocean water aquariums can't find the success key. The hatchlings live in the water column for roughly a month before they settle and become benthic. Getting them from palegic to benthic has proven painful (most studies are done on the Mediteranean vulgaris in hopes of raising them for food). Other members in you situation take the challenge of how many days can you keep them alive. One member reported 21 days and the next was around 11, most are 2-3.

- Feel free to experiment with the hachlings with any foods you can think of. The standard fare has not worked so any experiement is acceptable. Unfortunately, there is not much guidance but look in the raising Octopuses from Eggs subforum, paying attention to any of the threads "stuck" to the top and highlighted in green.

- I am assuming you know that your female will only survive as long as the eggs need her for hatching (or would have if they are not fertile). It seems that females laying and caring for fewer eggs live a little longer than those with large broods but that is poorly observed antecdotal timing (not being a scientist, I can get away with seems like somewhat safely :wink:).

- If you can get your camera to focus on the eggs, taking pictures every few days makes an interesting album.

Best of luck and if you choose to attempt to beat our record, please journal :biggrin2:

Hello,

The eggs are rice size. The octo was introduced about 2 months ago. The Octo stopped eating a few days ago so I was worried about it. I decided to move some rocks around to check on her when i noticed the sacks. I want to take pictures, but i'm afraid of disturbing and stressing her out anymore then i did earlier. I've at In the tank I have a few feeder damsels, and a large decorator crab. Should I try and remove them? She is currently in a 100 gal tank with live rock and #0 live sand. If the eggs hatch what should I do? What shall I feed them?

Sorry for the questions i'm a octopus newbie. Thanks everyone for your help!

Sincerely,
giar

Cool octo!! I believe D was right with suggesting macropus. damsels are never a good idea, they can cause harm and stress for the octo. and will certainly eat babies when they hatch. The crab should not be an issue. Being that they are small eggs there is not much you can do. As far as feeding try whatever the smallest live food you can get your hand on.

I heard artemis is bad? What other live foods do you guys suggest and any suggestions as to where to purchase them from? Will I stress out the Mom if I move the rocks around in order to remove the damsels? I've been doing a 15% water change every 5 days should I continue to do so? Again i'm sorry for all the questions. I just want these octopi to have a chance.

I don't recall any Macropus hatchlings. Beldar did brood but we never saw young but she had been in the tank longer than we think the sperm stays viable. If they do hatch please do your darndest to get a few pictures. The easiest way will be to catch one (turkey baster or cup recommended) and put it in a clear shallow container with tank water. Photograph with a dime under the container and/or a ruler.

I have only had one batch of palegic hatchlings and they were squid that died within two days. They reminded me of fleas (they are that tiny) and were about the same size as my infertile O. vulgaris eggs from LittleBit (that are still sitting in saltwater and still have not deteriorated :roll:). Do some reading in the thread I mentioned for some ideas.

I will definitely document everything I can. I've breed tons of fish but i'm very excited about this. I will do my best not to disappoint. Any suggestions on food? Is artemis a really a bad source? I feed my corals artemis. there are mysis in Lake Tahoe, but I have no idea on how to catch them.

We have had zero success raising the initially palegic animals so I can't tell you no but they don't keep cuttles alive and it is probably the most tried food in the universe. It may even be that we need to add something to the water (I even had egg white in one of my nurseries for the albumin, something one of our grad students thought might be missing). We really don't know that they starve to death, we just know they die and in great numbers quickly. Far too fast to suggest cannibalism as the culprit though it is likely it occurs later.

With the large egg O. briareus, I set up a counter with everything I could think of (large egg are not easy, just not impossible), including a footbath (the black dish in the photo is a brine hatchery). The two that survived (out of 5 that I think should have) were two that were in the large tanks. Both had spent time in the filter sock. Neal set up a mini filter sock arrangement for me when we expected hatchlings again but the eggs were not fertile and Cassy and Tanks offspring only lived a couple of days.

If you have a couple of buckets or small tanks (notice the conglomeration on the counter) go ahead and try any idea that comes to mind. You will only have a couple of days so don't dally once they hatch. The longer successes with the small egg octos have been in the primary tanks. We have no real clue why though. Keep in mind they won't live a day with the fish in the tank.

The ONE food that we know has had limited success - and I do mean limited - 4 out of over 10,000 vulgaris in one cast (the 4 did settle but did not live to full adults) and only a very few of an Alaskan species that I am not familiar with. If you can find anything that approaches hatchling crabs (if you find some frozen (or other crustacean) or as part of something (not dried), please let me know), crab zoea was part of the diet in both cases and thought to be a contributing factor. I froze some crab eggs when I last was able to get berried crabs but have not used them.
