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.


Hello D,

If you are willing to part with some crab eggs . I would be glad to purchase some from you if the eggs end up being fertile. I would also be glad to send you a baby assuming the rarity of some surviving if that interests you. I willbe photographing and posting pics tomorrow when i remove the damsels. Please let me know.


Sincerely, Giar.

Thank you for the thought and I hope you make me eat my words BUT please go at this as a project for learning and not for raising a tank generation animal. I would love another Macropus as the two I have had were very personable (as long as you played with them at 3:00 AM :roll:) but I won't hold my breath :wink:

What I have is a thimble's worth of frozen eggs that I took from newly dead, fed or dying females. These are not hatch zoea but the closest I was going to get. I would be willing to send them but they would not keep if they thawed. I do have a hefty smaller cooler that came with some frozen fish food and probably some ice packs but the cost of overnight even with the post office is steep (and may not be available in Gainesville - we have very limited overnight service with the USPS because most everything goes directly to Atlanta and then to us). The box would weigh more than the eggs :biggrin2:. Let me see how much it would cost to send them but I am thinking it is not workable (we are having excessive heat and it is not even August). We used to have a place for dry ice that might have faired better but it has been closed for several years.

Watch for eyes on the eggs. If you don't have one, even a dollar store ($2 now I think and $5 at the grocery :biggrin2:) 2x or 5x magnifying glass (anything stronger won't focus) is helpful. I have several and have used them to increase my camera's vision into the tanks (I don't have a macro lens and the macro setting does not often focus in the tanks).

On thing you can try, is to get a pair (two to a net only or you will only end up with two and maybe only one - Hannibal was removed and place by himself in another tank after one such trial) of peppermint shrimp (you can try others but I have only experimented with the peps) and keep them in a breeding net (easier said than done, they can exit if it is not covered) and overfeed them in the net. Peps (and most if not all) shrimp are hermaphrodites so any pair can create offspring but a pair is required. This seems to induce mating and spawning more frequently than just loose in the tank (they will eat the octo hatchlings but are fine for anything as big as they are and they are very helpful to keep aiptasia under control). They won't produce enough to feed as a primary food but may help. Unfortunately the hatchling shrimp don't live long but my pipe fish and mandarin loved them.

If you are adventurous, turn over a few rocks (putting them back in the same orientation) and look for any kind of invert that might have eggs. If you are near the ocean, look for crabs. Check in with any mom and pop restaurants that serve lobster or crab and see if they would keep any they remove (preferably raw but we are on an adventure). In freshwater the only thing I can think of would be crayfish and I am not sure of their spawning season. Commercially, I have seen Oyster eggs (they come in what looks like a face cream jar). I have never tried them but it is on my list to locate when I have viable eggs again (neither of the two I have now will so it will be awhile).

Think about how you are going to keep the dead food suspended to look like live. These are pelagic hatchlings so anything dangerous should be kept close to the bottom and shielded from drawing in the fleas. :biggrin2: Numerous air stones might provide the current you need without being problematic.

Haha 3 am. That's no joke! I completely understand were you're coming from when you say "Learning project". I do have a diamond loupe so I will be looking out for the "Eye dots" I will post pictures as things progress. I was thinking of putting a bunch of turbo snails in the tank. They always seem to be laying eggs on the glass. The LFS carries Oyster eggs, Arctipods, Mysis, Rotifers, and a few other items. I was also considering acclimating ghost shrimp to salt and harvesting their eggs. Another option was driving to a chinese market and asking for female crabs. Heh, It'll be a meal for all of us! I'm gonna wait a few days then update her status. Damsels have been all removed. Here's the best picture i could get!

GREAT find (I save the seller's store in my favorites). Expensive but I think it is a must try when I next have hatchlings! You might also write them if they can provide the smallest possible foods (and ask for suggestions). The mention cuttles so they have some idea of the market and their rating is extra high so I suspect good customer support.

I am excited to see that my suggestions have you thinking creatively!

It looks like you have a good view of a lot of the eggs so I am holding you to your promise to take pictures. I suggest trying to set a schedule of taking pictures every two to three days and only keeping one or two of them each session so that in the end you have a series. I did this with both Kooah and Mama Cass and found I would see things in the pictures that I missed with the eye. The embryos will flip twice during their maturation (assuming all octo embryos follow this pattern - as far as I know it has not been determined why they do this). The second flip (returning to the original positon) should imminent hatching. I was able to catch pictures of some of the eggs in one orientation and the others flipped (started photographing daily at this point) with Mama Cass (here is a photo in Kooah's Raising Octos from Eggs journal. Her own journal has week to week photos individually posted). Setting a photo schedule also helps make the waiting time less like watching paint dry :biggrin2:

Here is a photo from today. Unfortunately I do not see any black dots in the eggs yet. She's been trying to move rocks in order to cover the exposed photo area. \She'll move in order for me to snap a quick shot, then quickly returns.

Giar,
Please introduce yourself to Octo.. on his Raising Octos from eggs thread . He is going to attempt Abdopus hatchlings simultaneous to your attempt so note comparison may help both of you (and the rest of us :biggrin2:).

I was surprised the eggs were out in the open. I have several videos of animals securing their dens to keep the eggs well hidden. The most extreme case was with Kooah and I never would have believed she could move that rock through the tube. The funniest was Maya as she planted a "tree" outside her den.

My Abdopus keeps so many shells in front of her den you cant see into it at all. I have to add a crab in the tank so she leaves then shine a flashlight in, then get a 3 second look before she gives you the eye and blocks it all up.

Thanks D!
My order from ebay arrived today! Looks good.

Hello Octo!

My girl is trying to rearrange the live rocks. She swims away allowing me to photograph her for about 10 secs. As you can see in the photo, the rocks are placed against the glass which I cover with a black shirt. I think it keeps her from being frightened. Octo do you have any pictures of the eggs? Do they look anything like the ones in my photo? I'm just trying to figure out if they're fertile.

D,

Maya's Video is amazing! Today she pulled in more rock trying to prevent me from my occasional peek. She usually completely covers the eggs but when i move the shirt it she takes off for a few secs. I think once she realizes its me she returns.
