Most of the eggs hatched last night. I set up a snagger since I didn't have time to set up for the pot to hatch in a new tank and I worked late. The snagger didn't catch any clownfish larvae. There were still some eggs however, so I siphoned-scraped them off with a straw and set them to tumbling. There were probably just 20 eggs or so left. Hopefully they will hatch soon!

As of 10PM there were three that hatched. The remaining eggs don't look great, so I'm guessing they won't hatch, but I still have them tumbling just in case. I put the few larvae in with some day 2 D. lineatus larvae. The female is starting to get plump again and I'm hoping the next spawn will be larger and that I'll be home the night of the (main) hatch.

The rest of the eggs (all 10-15 of them) didn't hatch. I saw a couple of the larvae that hatched last night swimming around this morning. Hopefully they stay strong!

Another spawn yesterday. It is noticeably larger than the first nest, but not quite double the size. Once again, they seem to pay little attention to the eggs.

Hatch last night...sort of. Most of the eggs disappeared several days before they were due to hatch. Last night I siphon-scraped the remaining eggs off (they are in a tank where collected the larvae is not possible and the clay pot they are laid on is covered with..stuff so I don't want to take the entire pot). Nearly all the ones that ended up hatching did so within the first hour or so, when the lights were still on over the tumbler. I ended up with less than ten and they didn't look strong. We shall see...

Four left this morning (day 7). I have to do water changes to remove rotifers at this point. I have also given them small amounts of nhbbs. Tomorrow I may try to get them on enriched bbs, and today I will probably give them some crushed flake.

The settled one died yesterday; I suspect sudden shock. Still three left cruising around though. There is also a nest due to hatch tonight, so I will likely pull that and perhaps try them in a BRT. We'll see. This nest is larger than the last ones, so I don't want it to go to waste...

Last night I pulled the pot, and only a few hatched. A few minutes ago I used to straw to agitate/scrape the remaining eggs off the pot and a few more hatched. I plopped them back into the larval tank and dripped another gallon of ASW into the BRT (already ~5 gallons in there).

I tried to remove most of the unhatched eggs this morning. There aren't a ton of larvae, but more than five this time at least. The older batch has one settled and two larvae left. I'm hoping they settle soon so I can finish taking down and moving that larval station

Settlement is done today (finally) Only a few of the younger larvae are still alive. This bad hatching issue is quite annoying.
