The stars align - False Percs finally lay again!

Hi, I am no expert however I just read Jojce Wilkerson's clown fish book. She said that the larva tank should be covered on the sides to keep out light as it confuses the larva. You are way ahead of me so please don't take me as a know it all. Just trying to help. Congrats on your spawns. :)
 
I used to cover my sides. Not to discount Wilkerson but I have found it does absolutely nothing. (with my fry) What does work (for me) is keeping the water nice and green. Other than that I don't think the sides are important. If they are dying on day 1 or 2 I agree its either physical damage or initial egg / larvae quality likely caused by brood stock diet. I'm not sure a siphon is that easy on them though. It is a vacuum after all. That being said I have batches at times that just die like crazy on the first day or 2 and I use the tile method. Sometimes its just not meant to be I think.
 
Update: The remaining 10 from the first batch to fully survive meta are doing well. All are growing, they are on otohime A 100% now, with 50% water changes every 2-3 days and smaller changes in between. I have moved them (still in the bowl, there are only 10..) to a new location with a normal FL light. They seem to be doing very well, and are forming some sort of social hierarchy. Its fun to watch.

The last batch of eggs (the one I was not really expecting so soon) was about to hatch yesterday, so I relented and pulled about 75% of the nest via the tube method. I had 100% hatch last night about 11pm (lights out at 9:30). At about 11:30 I transfered them to the bowl, and I already noticed the quality of the larvae did not seem as good. Many (probably 50) were on the bottom and not swimming well or at all. (this is before transfer)

I transfered them all anyway, probably 250 or more, into the already prepared bowl. (It had been ready with rots and GW at 82F for a day already). This am (6 hours later) all but about 10 are dead. I siphoned them out, and observed them. Some are "circle swimming" others just lie on the bottom on their sides and dont move. I disposed of the dead, and hope the remaining 10 or so that are swimming normally will survive.

Interesting side note, between the last nest and this one, she had probably eaten almost nothing but pellets. Survival to day 1 is going to be about 5% tops.

I guess I need to relent and make some of my "own" food. The store bought stuff is too big (she loves it but spits half out because the pieces are too big), and pellets just arent good enough for a breeding female.

On the plus side, I'm getting good at all of this now, its almost second nature.

So you are moving them from whatever container you siphoned them into to another bowl later that has GW and rots right? If so I wouldn't be moving them into different water so soon. Even if it does come from the main tank. Things change quickly in water. Especially with no filtration and with the addition of Rots / Phyto. I would siphon them to the bowl using the water from the hatch vessel and add the phyto and rinsed rots to them. They are very fragile at that stage. It may help your survival rates. I'm glad things are becoming easier for you :)
 
Currently I have tried a couple different methods of transfer from the hatching vessel (funnel).

- I have siphoned them directly to the fishbowl, then added (dripwise over about an hour) clean tank water. Then dripped in greenwater/rinsed rots.

- I have siphoned them to an intermediate vessel (tupperware) and examined them, removing any dead ones and the egg cases via suction, then transfered them to the bowl (containing tank water, same temp, same sg, etc), then dripped in rots/GW.

- This last time I siphoned to intermediate container, removed dead and dying, and transfered to 1-day-old tank water/rots/gw.

All yielded about the same results for me - 90% fatality by end of day 2.

Next time I will probably go back to method #1, or possibly simply "pour" the whole funnel into the fishbowl (about half filled with tank water).

I really think its nutrition. I will be getting some frozen "mixed seafood" at the asian grocery today, and some Tobiko or other fish roe.

I agree. I feed mine that mixed seafood medley stuff. I blend it with a couple sheets of Nori and some water. Make sure its all uncooked though. Sometimes the mussels are cooked.
