[Cuttlefish Eggs]: They Have Hatched

There was a point when I realized my cuttles were eating better than I was...

It is possible to have more than one female lay eggs in a clutch, so there is a possibility they aren't all related...
That could be, also my batch of eggs are from two different pieces of media, so chances are they were two small clutches or the wholesaler just through two clutches into the bag, as I picked them up directly at the airport, before my retailer took them to the store.

As far as breeding siblings, the only way I can guarantee that I am not, is to separate the sexes the best I can and use the from different groups, as by controlling this I am hoping to see if it gets around the Gen2 Barrier or reveals if there is some other variable that could be causing these low yields on captive produced eggs. Just trying to advance the understanding of these critters as a steady captive bred supply will greatly help the hobby

I know @Thales has managed at least Gen2 and there may be others but success rates are not high so it will be interesting to see if your strategy helps. A suggestion is to keep them on live food. @cuttlegirl has suggested this in the past and the only eggs that matured from my group where those laid while feeding live. After I switched to frozen, none of the eggs developed. The evidence is anecdotal and may not be related. It is one of those experiments that are hard to justify but worth the knowledge for others.

Here is some uneditted footage from this morning, from shortly after the lights were turned on. Still holding at 11 babies, I'm thinking there may be two maybe 3 more viable eggs.

I just witnessed my first confirmed successful strike, I'm a proud papa. And the babies are definitely social now, as I've been watching them and they are definitely communicating with each other, waving their little tentacles around and changing colours. I'm still holding at 11 individuals, and the remaining eggs I don't have much more hope for... there are two eggs that I will give a few more days and then I will remove them to make room for the growing babies. I also have 2 more orders of eggs arriving on the 13th.

Not much to report, aside from running out of Mysids, as I was having difficulty getting brine shrimp eggs. who would have thought that their is a shortage of brine shrimp up here. I ordered a pound from the US, but unfortunately its taking its time to get up here. I managed to gets some eggs from a local clownfish breeder so I will be able to keep the next batch of Mysids from eating each other, hopefully long enough to get them into the sorting tanks. Though the sorting tanks are in limbo waiting for my micron mesh to arrive, again from the US. I still have 10 babies for sure, 2 got swept over the overflow during maintenance, and I've only been able to recover one. Granted the only fish in the tank they are attached to are Mollies, so the 11th cuttle may have a chance of surviving in their, as there is lots of microfauna, as the Mollies really are only interested in flakes.

Note on feeding mysis. I had no luck keeping them alive until I experimented. One of the things I found that I know helped was feeding them frozen Daphnia twice a day (I just happened to have cubes in the freezer so I tried them). Way easier and more successful than brine and I did not feed anything else. The other things I did (I was able to keep some alive over a month where my past experiences were less than a week - same supplier) was to NOT change their water, used live rock (from my tank) only for filtration (probably gave hiding places), used a circular tank (bio-orb) and a VERY gentle circular curtain of air (like this). Outside the twice a day feeding of Daphnia, I am not sure how much impact the set up made but I would definitely do it again this way.

Well my Mysis arrived, and well I have only lost 1 baby during the "No Mysids" time. They really didn't like amphipods and BBS. Since they where really hungry when I put the Mysids in I decided to film it a bit. So here is the raw video, as I'm still learning this editing thing.
I filmed it in 4K so that I can zoom and crop later in 1080, once I figure out how to do it.

I had BBS waiting for when my Mysids landed and within 30 minutes of being released I can see little red spots on their tummies, so they are definitely eating the BBS. Starting this weekend I'm going to try and decapsulate, in order to not have to worry about removing the egg casings as well as removing the chance of getting hydroids in my Mysid tank.

A Long overdue update. I still have 5 cuttles, 3 from the orginal batch, 2 from a different clutch that are 3 weeks younger. Last week I moved them out of my breeder and into a 5 gallon section that I use to grow out Mollie Fry, key word is I used to grow out Mollie fry in there, as the little predators devoured 35 new born Mollies over night, and started to make a dent in the 1" long group... They still get live Mysids, as well as live Cherry Shrimp when I'm culling, but I have finally reached a mile stone. All Five will take PE Mysis off of a "Stealth Stick," and my largest will even take frozen Mysids off of the bottom of the tank.

This mile stone will take much pressure off of my Mysid tanks, as I have eggs arriving next week in an attempt to get my breeding project off to a diverse start, I also have 100 fiddler crabs arriving so we will see how those go.

I am in talks with a wholesaler to get setup so I can bring in ghost shrimp as feeders, as I haven't been able to find one retailer who imports the into Canada, and well trying to find the truly saltwater grass shrimp is completely impossible up here. In my talks with FedEx it appears as long as it is produced in the US it is fish and wildlife excempt, and they will ship to me, but most vendors don't want to take this risk. I am even considering setting up a tank just to rear peppermint shrimp, as they are available up here and their larval stages aren't too difficult to get to settle.

Ive been in talks with livebrineshirmp to get her shrimp and micro crabs but so far I can only get them as far as Montana, so I may be looking at a 16 hr round trip, trip, to get some good food for my little guys. If I can get the tank cleaned up a bit I'll probably take a video tomorrow of them feeding, but since it has just been used for Grow out, and is hooked into my larger system, its pretty scummy.

What is a "micro crab" (the only thing I find under that common name are freshwater inverts) and can you provide a direct link to livebrineshrimp's page? Small saltwater crabs are always of interest.

Well Looks like I quoted the name of the crab incorrectly, they call them mud crabs, shell size between a nickle and a dime.... they appear to be a fiddler species Ocypodidae Uca -pugnax, though starting at 3.00 per dozen plus shipping they would be a good deal for us land locked ceph keepers.www.livebrineshrimp.com
