Aculeatus Hatchlings

Well several hundred little babies are off to a few new homes. We split them up and spread them around so we can learn as much as we can. I am optimistic that there might be a chance with the different foods that will be tried.

Thanks for octopus paralarvae. I am trying collecting plankton with a plankton net. It looks like some researchers may have had some success
raising octopus paralarvae. Below are a couple of references. Copepods
may be a possible food source. They used live king crab (Lithodes santolla) zoeae. Juvenile (1-5 day) Mysid shrimp might be a good food source but they are 50 cents each.

Rearing and Growth of the Octopus Robsonella fontaniana (Cephalopoda: Octopodidae) From Planktonic Hatchlings to Benthic Juveniles

"R. fontaniana could serve as a reference model for rearing other cephalopod species with planktonic phases (González et al., 2008; Uriarte et al., 2008a, b; Pereda et al., 2009)."

Thanks for the opportunity with these. Some results here:

Day 4 - Down to 1 this morning.
I cannot get a picture showing it, but there is a light red / pink spot inside of mantle, just aft of center. I'm unsure of where gut might be located.

What I fed:
New hatch artemia
Tigriopus califoricus
Copepods and tiny isopods vacuumed off glass of cuttlefish display
Mortor / pestle ground flake and shrimp pellet (one of my mysid foods)
Frozen cyclops

The set up for the 100+ hatchlings:
5g aga w/ screened bulkhead drain, plumbed into a 165g volume reef set up.
"very low" flow
I neglected to light block tank the first day, but did there after.
End of day 2, I transferred 8 surviving to a small Dip-n-Pour inside the 5g and reduced flow (in it) to a trickle
End of day 3 had 2 surviving

Excellent photos here:

We tried to take pictures of a 32" display hooked up to microscope, but mine didn't come out well.

Yes, forgot that one. I did thaw a cube of SFB frozen cyclops and drew out just a little for the octopus. I remember seeing that bright orange in mysid guts.

You can try soaking all the food in the Cyclop-eeze just before feeding. For my briareus (large egg, benthic) hatchlings, I seed the tank with a mixture of Cyclop-eeze and Frozen oyster egg and then let whatever I am going to feed sit in the remaining saltwater and thawed mixture. Since one of mine will turn upside down and troll the surface, I suspect it might help for the peligics as well.

I realize its too late for this batch of paralarvae, but if you or anyone else has any octos that lay eggs I am doing a graduate project on the paralarvae. The only issue is that I need the eggs before they hatch. I have tanks and everything setup so it would be relatively easy for me to get them on short notice. Any help that I could get with this would be very much appreciated.
