New hatch

Back from various trips, I am waiting for the remainder of the Ocellaris eggs to hatch. I already got a boatload of larvae, but, I suspect there are more eggs to hatch--alright, I looked at the parent clowns, and they are still working the nest. So after delivering the shoebox of larvae to their new home tank, I set the snagger back up to collect more. So far I have a few more, we will see if this was worth the effort.

Don't you just love the smell of newly hatched larvae? Ok , I've got it bad....
:p

Umm............yea.
 
I got tired around midnight and decided to leave the snagger on all night. There was a risk that I would lose what I collected, because they might get tired out from the current in the box, but I had already moved the majority of the larvae to their new home. Anything I collected overnight was gravy. Sometime during the night the batteries ran out in the pen light, but I did collect a fair amount of larvae, and they were still alive this morning!

Two disadvantages to the larval snagger:
1. It is hard setting it into the tank to get the height of the hole just right so that the pump does not empty the box.

2. It is hard to carry the full box downstairs without spilling water and larvae.

On the other hand, it collects a bucket of larvae--more individuals than I ever got hatching eggs!
 
Glad to hear you're back on it again Kathy, been a while since I've seen a new hatch post from you. Same here though, but I'm down to ONE baby from the ones I kept, he's sellable now, but since he's the only one left, I can't let him go ;) I'm keeping more from the next set.

I love the smell of larvae in the morning, smells like VICTORY. :smokin:

NOT what I was referring to. :)

The smell this morning was not bad, but there were at least a hundred dead ones in the tank....I don't know why and don't have time to test water quality, but at 24 hours I hardly think ammonia is the problem. Still many alive, looking good, rotifers look good.

I think this is just one of those "Oh, well" moments.
We push on. :(
 
Tested the water, no ammonia.

Upon reflection, I know there were a couple of things I did wrong. One was to forget to plug in the heater when I set up the larval tank. Because I was using diplay tank water, it was warm from the get go, and I did not check the temp later. Got down to below 70 overnight, and in the morning, before I knew of this mistake, I put the overnight collected larvae and their water into the tank--it was 80 degrees, and raised the tank temp to 70!. So both sets of larvae got temperature shock. Then I plugged in the heater, and over a couple of hours the temperature shot to 84! I had used this heater previously in a 20 gallon and it kept the temp at 80, but now, in the 10 gallon, .....I didn't think it would heat differently.

The other thing I may have overlooked is how much energy the overnight collected larvae expended trying to deal with the current caused by the pump all night in the larval snagger. They may have depleted their reserves by the following night.

Did I add too many rotifers? Maybe there was an oxygen depletion. I have since added another airstone.

I have had no deaths all day, so perhaps the massive death thing left only the tough ones, and I will have some luck with the remaining larvae. There are quite a lot of them despite the massive death. I am having no trouble keeping them in rotifers, in fact I did not have to add more this evening. They appear to be feeding well, are peanut shaped, and striking at rotifers. Fortunately, life goes on...
 
No dead ones this morning! I decided to keep them at 84 degrees, because they have already had enough temp swings in their short life, and it may make them grow faster. I already think they are big for 2 day olds.
 
Unbelievable!

Unbelievable!

It was the afternoon of day 6, and gazing at my larvae, as I do rediculously often, I thought I spied a white headband, and there's one that's orange!

This evening I came back from a wedding reception to a tank of larvae half of which are sporting white headbands! It's day 6! Several larvae have lost their dark pigment, and are orange. Previous batches from the same broodstock did not get headbands until day 10 or 11.

Is this because of the increased temperature, or the incredible quantity of food my female ocellaris is consuming?

A little bit of both of those and a whole lot of a bunch of other stuff that just happpened to line up in the right order, keep up the good work. That stuff about everything lining up gets easier and easier all the time, you'll see.
 
I think you are right. It's the lining up of a whole bunch of other stuff, including temp and feeding. Thanks, Dman.

I have to agree, I can't put my finger on anything in particular that changed at my house but suddenly everything is in sync and it's like a machine. I really think a lot of it has to do with routine, at first you spend way too much time thinking about what you are doing, second guessing yourself and making changes to try to improve. Eventually everything just becomes automatic, any changes are very subtle, and that seems to be where the real fun starts :D

I think if someone new to breeding wants to know how, I'd say "paint fence, wax on, wax off" :rolleyes: IOW culture rotifers, hatch artemia and get some empty tanks. Feed and clean those empty tanks and do daily water changes. You won't even notice the day when they are full of baby clownfish :cool:
