yeah surprising that works. I would figure some sort of kriesel for them
RLTW 180 Gallon Mixed Reef Then I heard the voice of the Lord saying, "Whom shall I send? And who will go for us?" And I said, "Here am I. Send me!" Isaiah 6:8

Yes that is all I have done up to this point. They sit in the tank to maintain certain temp. They will be moving to something else soon thought.

I would try them without the air bubbler. You'll get more hatching. Also, hydrogen peroxide baths for the eggs help tremendously.
Good luck!

Well guys I have bad news. Today was day number three post hatch. I did not do anything to the larvae yesterday. Today I came to fine that about 10-15 of them where swimming around in my little bucket. I took a salinity reading and it was up at 35pp. So I decided to do a water change. I used water from the main system mixed with some fresh RODI water and did a small water change. I was hoping to get the salinity back to around 30pp. I did the water change by dripping. I think I did the water change a bit to fast because after the water change I had lost about half of the larvae. I think the change in salinity and maybe the temperature difference may have shocked the larvae. I also ran some chem test to see how the water quality was NH3- 0.08 and NO2-0.107 not terrible but not perfect either. By the end of the day all larvae where dead. Record so far 3 days post hatch. I dont see a reason to do anything to the eggs right now as I am getting a go hatch rate out of what I am catching. I am losing a lot during day 2-3 and that could be because I was not able to top off and do a small water change on day two. Good news is the egg collector is in and should have more eggs tomorrow. Here is a picture of how far the little guys where developed by day 3.

Three days post-hatch is about normal for losing the prolarva. I would give Luis' system a try (in his angel thread?). That's what I'm going to try as soon as I get a little time.

Hey guys it has been a little while since I have posted but there have been some upgrades. Here is the last batch of eggs and prolarvae    I am moving away from the plastic cup into a flow through system. I have not used it yet as I have not been getting good egg collection. But here are some pictures. They are just easy black carry out containers. There are two of them. The top one will hold the eggs and Larvae I will drip water into the top one. There is a small cut that has a screen on it so the larvae and eggs will not flow out. The water will then fall into the next container. The water will fill up the container and then drip out of the holes in it. The water will then return to the system. Here are a couple pictures. Here is the top one with the drain and screen cover.   Here is the bottom container.   The egg crate is in there to space out the containers so the water can flow through. Here is a picture of the full setup.  I have not yet used this system still waiting to get another collection of eggs. They will go into this new system.

I am amazed with the dimensions of your tank,the size of a public aquarium display  .Could you tell us more about it,its measures,is it made of concrete with window panels? This tank will provide you with a wealth of eggs of many species.  The yellow sphere is the oil vacuole,not the yolk sac. For some reason,we all in this site are finding the same prolarval mortality problem,and,as I said,solving this issue ,which I suspect the same in all cases,will open a new era in MO aquaculture.

This is the rule most scientists use.But not all of them,see in the link provided that the term prolarva is not used,they are called larvae since hatching.It is mostly a semantic issue.Pelagic eggs hatch in the embryonic stage,but they cant call an embryo to something that hatched and swims free!

Well thanks to the MBI Workshop and Eric Cassiano for getting my motivation to get back on track with this project. Looking forward to getting some more updates on this project!

These look the same as the [blue tang prolarvae I have been working on. [They have a similar shape and the eggs look like they are less than a day old. I have only really seen two varieties of prolarvae so I might be wrong. [If they are some sort of tang/surgeonfish then rotifers will be massively to big (about the same size as the entire head). Thread and lots of pics here http://www.mbisite.org/Fo.ms/tm.aspx?m=63962

Well guys. Following Todd and Erics advice from the Workshop. I put in a net to catch some eggs just to see what my egg collector was missing. I could not really tell how many where actually caught by the net. I did however end up with another 6-10 eggs which I put into another cup to hatch out. They look exactly the same as the eggs that have been collected before. I will be turning off all pumps and try net collecting tomorrow night. I am hoping Erics ideas of catching 1000s of eggs will be right! Will update once I know what I get tomorrow.

Regarding the egg collector,is it fixed to something or free floating?
Water level is slightly above the edge of the horizontal cut in half pipes?

The collector is fixed and does not move around. The water level is in the middle of the pipes that are cut. This may change after talking to Eric at the MBI workshop he recommended to increase the drain size and to get rid of the the other pipes as it may not have a strong enough sucking to over power the drains on the aquarium. I dont know what I am going to do yet. Regarding my collection once turning off all the pumps in the system went well. I collected between 100-1000eggs. This took place on the full moon. I also was not able to turn the lights off till just after sunset. I let the fish do there thing for about an hour before I started collecting eggs. I used a net and just ran it over the surface of the aquarium. Fish that I saw showing signs of spawning where: Lookdowns, Saber Soilders, Atlantic Blue tangs, sailfins tang, yellows, hippos. Again I am not sure who was spawning or not. I will get a better count tomorrow and decide if I am going to ship to Eric and Matt down in FL.
