Hi all Newb here, I have some questions about caring for octopus eggs. I recently purchased a Dwarf octopus from a guy that breeds them near me. I had picked out what he told me was a male octopus. I have a 12 gallon nanocube that I have plumbed into my 100 gallon reef aquarium so it is easier to keep the levels maintained. She has this tank all to herself. I put in some pvc pieces for her to hide in she quickly made a home out of one of them. She never came out not even to eat, so I would give her the food while she was still in the tube. After a few days I pulled the tube out of the aquarium to check on her. Once I pull it out she came out of the tube and inside the tube I saw all these sacs attached to the tube. I realized they were eggs so I quickly took some pictures and put it back in the water. I have been feeding her every day in the tube and she eats everyday. I have been browsing the forums and can't find the exact answers to my questions. The questions that I have are first what should I be feeding her? I am currently feeding her raw frozen shrimp tried scallops but she wouldn't eat them. How long until the Eggs hatch? She laid them about feb 20. What should I feed the young fry? I have a reef aquarium with a large supply of copeopods, anhropods and other misc small critters or should I feed frozen mysis. Then what is the best way to get the food from my main aquarium to the new babies. Should I seperate the mother from the eggs or after they hatch? What is the Ideal water temp for the new babies? Any help with these questions would be greatly appreciated. Attached are some pics of the eggs and the mom.

:welcome: to TONMO!

If you haven't found them yet, dwhatley's "trapper" and "trapper's babies" threads are probably the best reference for your situation, and gholland is in the process of something similar. It looks like you have a large-egged octo, which makes it possible to raise raise young. Dwhatley feeds mother octos primarily cyclop-eze, see her posts for details...

It sounds like you don't know the species, but it's consistent with mercatoris. I'm surprised that she let you take those pictures, since normally they really don't like to be separated from their dens when there are eggs... was she OK with that for a minute?

In any case, it's pretty hard to ID a living octo as male or female, particularly a small one where you don't know the exact species... mercatoris are a bit easier than some because the males have some oversized suckers, but they're pretty hard to spot unless the octo has his suckers positioned to give a good view.

anyway, searching for "trapper" is probably your best bet for stuff to read immediately, although there's no "distilled" version like an article or FAQ.

Thanks for the quick reply. She is a Dwarf octopus "Octopus joubini " I will check out the Trapper. She is ok for a minute being seperated. However I don't have to seperate her to take the pics. The back of the pvc has a screw off piece that I can take off while she stays in the front gaurding her eggs. Here are some pics from today.

YOu don't need to separate Mum from the Hatchlings. The sad fact is that nature will do it for you, most octopus die after breeding :sad: . The pods etc from your reef tank sound just fine for the babies. Transfer either by moving a piece of the live rock (no anemones or corals attached...very bad for the babies) or scoop them up with a very fine mesh net. The water temp for the babies should be the same as for the adult.

Cheers

So any ideas when I should be expecting the eggs to hatch? I read somewhere on here about 50 days for the gestation period but it was for a different species would it be the same for mine Dwarf octopus "octopus joubini". And then if you look at the second set of pictures that I posted not all of them are developed as much as the rest will those still hatch?

Great pictures! Looks like you've been pointed in the right direction. Dwhatley's threads are probably the most detailed literature you're going to find on the subject. I'm sure if you read enough you'll find the answer to your gestation period question, but I imagine it's going to depend on a few things, like water temperature and flow.

Some of the eggs might not develop but looks like the majority of yours are well on their way.

azreefguy,
How big are the eggs? Our O. mercatoris eggs were about 8-9 mm long... O. joubini eggs will be smaller and from all accounts, virtually impossible to raise. If they are the larger size, then you probably have O. mercatoris. Our eggs took between 35 and 50 days to all hatch out at an average temperature of 75 F. Copepods and mysis have done great for our babies (Varys) and they are now eagerly taking frozen foods at 1 month of age.... Guess I need to update our thread, eh?
