URGENT: Aculeatus Hatchlings (octopus) in NH

Postby Flighty » Wed Jun 23, 2010 12:29 pm

I have about 30 hatchlings in a krissle and am not able to try raising them this time. I know it is a long shot, but if anyone would like to try them in my area, please contact me right away. I hate to just let them die without asking if there is anyone who might try to learn something.

This is a small egg species that has not been successfully raised yet, but the babies are active and striking at critters from our macroalgae.

Thanks. I wish you were closer. Failing that ( :) ), good luck finding someone to try them out. Congratulations on the hatch and good luck with them. (Nice pictures, too.)

Nice to meet you today. Hope the kids enjoyed the NEAq.

I have a 100+ or so. Lets see how they do. I'll at least post so good pictures of them growing up hopefully.

Keep us posted. Everyone I know that has worked with them doesn't bother anymore. It would be great to crack this one. :D

Well they sure look like they would make nice fried appetizers. I'll post some pictures tomorrow, crazy little guys.

Great Andy - what are you planning on trying to feed them. Have you seen any strikes or darkened gut?

They are in a tank full of A. tonsa, adults to nauplii. 200L tank, with 150 octopus. I have seen a few strikes at the adult copepods, but they didn''t catch anything. I opened one up this afternoon and didn't see a lot. These guys are way out of my norm, so I'm still getting up to speed. I have no idea what normal behavior is, no idea what type of water flow, so we'll see.

Can't tell you how cute they look to me.
Any estimate of the copepod density of the tank they are in ? What kind of flow are you using ?
Good luck with them Andy !

Anderson,

I'm not sure exactly, been really busy with other things. I think its somewhere around 2-4 per mL. For now I'm just bubbling up the side of the tank, few mL per minute. Gives a slight turn to the tank. I'd like to roll the tank a bit more but these guys are strange and seem to like to swim up and drift down. They all have a nice ink sack and use it when exposed to MS-222.....

Is that still some yolk left in the belly in the second shot? Good luck!

Not sure, its a white spot, has some slight blue/purple in it under the compound scope when you dissect it out.

It kind of reflects like oils in that second photo.

Some still alive. They don't like the light. Right now our lab is under construction and we have no photoperiod control, Brad was in this morning and said the sun beams right into the larvae tanks. They were all piled up on the dark side of the tank. Fish larvae generally sit under or just on the fringe of the light. Still don't know if they are eating. I'll shot some pictures tomorrow or Monday if we have any left.

Do you have any harps you could feed them that are easier for them to catch? Or even newly hatched Artemia?
Or could you even try tiny pieces of table shrimp? I'm just thinking it looks like they could hold onto prey if it were easy for them to catch or even handed to them. You could spend your whole Saturday hand feeding 150 tiny mouths! And when you're done it's time to start over again! :D

Good luck with them. They sure are cute. Karen

Love the pictures! We met in Brunswick Andy - recall I asked you about raising small egg octopus.

Flighty, I am down to 2. Mike about 12. I lost 80% in about 14 hrs. from getting them. It was interesting that while acclimating, I watched one grab a little piece of flake food and swim around the bucket with it. I grind a bit for my mysids so put a tiny pinch in the hatchlings acclimating container. The piece was large relative to the "dust" I meant to put in there. I'd say it was about 1/2 the size of the spread tentacle radius in the above picture.
We didn't have a great plankton tow, and our captive copepod numbers pretty thin when this opportunity came up.
We were able to view live microscope images on 32" lcd which was amazing.

Good luck. Will be following along 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
Rotifers
Tigriopus califoricus
Copepods and tiny isopods vacuumed off glass of cuttlefish display
Mortor / pestle ground flake and shrimp pellet (one of my mysid foods)

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 to a trickle
End of day 3 has 2 surviving

Out of 8 that I caught after I got back from neaq and left alone in the kirssel (sp?) over the weekend with macroalgae and lots of pods and stuff from the fuge, at least 2 are still alive. The flow is low in there.
