No luck, above. Trying again. Got a fresh parvo culture. I'm waiting to add the nauplii until the larvae have eyes and a mouth.

I stopped trying for a while, distracted by other stuff. Recently I set up a larval tub for watchman gobies that hatched too early in the parental tank, so I didn't get the eggs. My Damsels had spawned as usual, so I moved the tile to the tub, and turned off the light, and an hour later, the tub was thick with damsel larvae. I returned the tile to Mr and Mrs Strom. This morning I fed the tub parvo nauplii, lots of tetraselmis, isochrysis and rhodomonas, some apocyclops, ciliates, and what could very well be O. marina. I moved the light down closer to the tank. Many fewer lavae darting around this evening, but still a lot. We shall see what tomorrow brings.

This morning I loaded the tub with parvo nauplii, and there were some larvae, but I couldn't find any this evening.

July 9: Added some damsel eggs to a freshly prepared tub, but containing Chryptocentrus cinctus larvae which hatched July 2 or 3. Many died but at least 2 persisted in a BRT with a single watchman larva, and all the live food items. It's July 16, day 7, and there are still a couple of damsel larvae darting for food. They share the brt with the watchman larva, more damsel larva, hatched yesterday, and some ruby red dragonet larvae, also hatched yesterday.

Tub 1: In the watchman tub, the new July 15th damsel larvae are numerous and swimming. There seem to persist a couple of damsel larvae from the previous hatch,July 9th! Yay!. Tub 2: The new damsel hatch in the freshly prepared tub seemed to massively die almost immediately although a couple survive. The Ruby Red dragonet larvae seem OK in this new tub.

Just reviewed my notes from the last time I got a damsel larva to live past 4 days. I lost it during the MBI 2014 workshop weekend. My older damsel larvae this year will be EXACTLY the same age as that first larva, when I leave for MBI this year. EXACTLY!

Day 12, still at least one, but it looks underdeveloped compared to the last time I got any to survive for a while. Tomorrow the tub gets a bunch of euterpina, tisbe, and brine naups since the watchman larva may be metamorphosing. Edit: the lone survivor turned out to be a runty Cryptocentrus cinctus-watchman goby. Much smaller than the other one, and looked so different in size, I thought it was a damsel….

Kathy, this may seem like a foolish question to ask, but have you looked into the scientific journals around this genus and its culture? Dascyllus was done a while back and multiple times over...I feel like you should have the materials and tools to pull this off.

yes I've looked. I hope get one this time. Luis A M says this one is particularly difficult as it hatches as prolarvae and very small. I suspect that those who have brought the through on rotifers had a particular ciliate contamination of which they were unaware.

Still have a little swimmer after MBI this year, but it is not as far along as the one from last year. I went back and recalculated the age of last years run and it disappeared after day 19, and had some color just before. This one is beginning to look like a goby larva , no color at all, and is at day 23. I wonder if it s a goby runt. It is significantly smaller than the one I know is a goby, and always has been.

It's got to be a goby runt. bears no resemblence to a damsel larva.

Ok, Damsels. Now is the time to apply learnings from MBI workshop to these amazing damsels. I've already turned the temperature down on the damsel parents. They spawned probably early this morning. Normally the eggs would hatch in two days. It may be later, and I hope it is, because I turned down the temperature to allow the embryos to get just a bit larger before hatching (thanks, Kevin Barden). I've prepared a 2 gallon pretzel jar (thanks, Ramon Villaverde) sitting in a water bath (thanks, Kevin Barden). I plan to feed the damsel larvae daily with lots of Parvocalanus crassirostris nauplii and copepodites and live phytoplankton (thanks, Andy Rhyne, and Ramon Villaverde). The earliest I can expect metamorphosis for this species is 16 days. Not bad. (thanks, Kevin Barden) I'll keep you posted.

I jumped too early. They didn't hatch and I am hoping they won't hatch tonight either. Isn't it strange that a lower temperature is supposed to delay hatch but not development or growth? I would have guessed the opposite.

Looking at the eggs last night, some died at an underdeveloped stage, yolk turning black. The rest had beating hearts and pulsing colorless blood through their veins. They hatched last night in the clean cup, not as many as I had wished, but probably enough for a 2 gallon pretzel jar. In they went with a ton of parvo nauplii and enough live Iso to tint a medium brown. When I put the Iso in, they all went to the surface. I lowered the light. I hope they are OK. The plan is to slowly increase the temperature, but I am leaving it as is for now.

at 40x, 80F prolarvae day0-1 at 20x, 74F, prolarvae day 0-1 not a head to head, same batch different temps, but two separate nests, so there is no control here, but kinda an indication that temperature of incubation matters.
