Sorry for the lack of info here right now. Got these eggs donated from a LFS near me. They just hatched and so far I count 2 larvae. When more hatch I will get a photo of one. They are a stream-line shape and are about a mm long if not smaller

So I managed to get a picture of two different larvae. The left larvae, I believe, is a shrimp larvae, because it had two phalanges that it was using while it searched or the panamanesis. The right one, I believe, is a fish larvae.

You will want to see if you can observe the fish larva "striking" at any of the copepod nauplii. You will also want to see if you can observe the larva's gut having contents -- usually a darkish or sometimes greenish or orangish line following where the gut should be. I understand that you don't really know what you are looking for just yet, but this is a good opportunity to start making these kind of observations, to train your eye. It helps to have a variety of magnifying glasses of various powers around. Good luck!

Jim, is the "gut's contents" in this part of the picture above?

Are you sure they are fish? Hard to tell in the pic but they resemble early-stage shrimp from that angle.

I truthfully have absolutly no idea tal. I know the one on the left is a shrimp larvae because it has 2 legs in the front and 12 underneath its belly. I have no true idea what an early-staged shrimp looks like, so I will do more research. Also, if you have a link, that would be helpful too

Ok so it turns out we've got a book on peppermint shrimp, and the only larvae that looks similar is the Larva on the left. The one on the right is just a singular streamline "thing" with no extra appendages on it

Wow! Thanks Jim! Now to see how long I can raise this single larve. It is striking at the Panamenisis that I have in there so I think I am in good shape.

The left one seems a Z1 shrimp larvae,but the one at the right looks more like a Mysis? Still,it is unclear how your LFS could collect the eggs,since none of them produce free eggs

My dad designed an egg catcher for them where the pelogic eggs get caught into it. The store owner told us that his fish spawn every morning. I will post more on the egg catchers design later on today

Ok. Time to explain how the egg catcher works. Here is the basic design of it: The tank has a 4" "lip" around the top of the tank. The pvc frame is attached to Lexan tabs that insert into suction cups. The two gallon bucket, cut short, has a 100 micron screen on the side to keep the eggs inside the bucket while still allowing water to flow through. Airlift comes inside the bucket to draw in the eggs. It fits below the screen net that is there to keep the fish from jumping out of the tank. The frame holds the bucket in the tank with use of friction.

This was started from the idea presented by Todd Gardner at the MBI workshop in 2012. In his presentation, he talked about using local aquarium maintenance vendors and their customers as a source of pelagic eggs. I struck a deal with one of our local companies. Here is a video of his 430 display tank: http://youtu.be/DSRUTM6vsr0

Today, the one shrimp larvae has reached the Z2 stage. When I feed the larvae, I put in mostly Panam. Nauplii, but I also put in a few adults for the shrimp to eat. His eyes have split onto small stalks ( I think that's what their called), and he has "antlers" as well.

Just got a new batch of eggs today. The shrimp larvae from the first batch were all eaten by the mysis shrimp then they all canalized themselves.

Exciting update! So far, I have 6 little pro larvae, I believe. And of course this had to happen a week before I go to Mexico! But I will try an get these guys to last as log as I can. I will feed these guys A. Panamensis F1 nauplii (Smaller than 120 microns and bigger than 48 microns.)

Prolarvae of what? And I think you mean "N1" nauplii.

I truly have no idea of what, and thanks for the correction. No idea what the prolarvae is, but it has, from what I can see, a head and still looks egg-shaped without a mouth and is VERY clear. I almost passed over them.
