When they look like that, they hatch that night. :-)

They did not hatch last night. So it must be tonight. Eggs are still alive. I put the pot with the majority of the eggs in a bucket with airstone, to preserve the vast majority, and just to see what happens.

Many hatched this afternoon in the kreisel: kreisel fuzzy white things are larvae: at 40x under scope: no eyes, mouth, in other words--prolarvae

I gave the kreisel a light Isochrysis dose and lots of Parvocalanus. More damsels may hatch out tonight. The bucket appears to be unhatched, but it is harder to see them in there, and the temperature is about 75, as opposed to 78 in the kreisel. More to come!

OMG! Overnight we had a massive hatchment! The kreisel has hundreds and I didn't think I put that many eggs into it. The bucket is just thick with them. I'll keep that as a starvation test. But I've already fed some to some larger fish, and haven't made a dent in the bucket population.

By Wednesday (2 days later) they developed pigmentation in the eyes, and were certainly able to avoid the pipet, in my attempts to capture one in order to look under the scope. By Thursday there was a huge die off, in both the kreisel and the bucket. Many floaters and motionless ones. I did a 25% water change with siphoning and skimming the surface. I think there are still some live ones in the kreisel, but its hard to tell, as there is a bloom of isochrysis. Anyway, starvation time is 3 days, coincident to the formation of the mouth, and disappearance of the yolk:

Have you seen them strike at/eat anything yet?

I'm pretty sure they are all dead, despite having lots of appropriate food. Probably the kreisel is not ideal for them. Once I get some space, I'll try a larger tub.

Still waiting to clear some space for a BRT, I still have the kreisel running on the shelf. It has a bloom of Isochrysis, P. crassirostris, and I'm afraid a few brine shrimp….dont know how they got in there... I scraped some eggs off the pot, and they look almost ready to hatch, so I added only 18 eggs this time to the kreisel. Perhaps the other die off was because of too many larvae in too small a vessel. It may be a little early, so I'll add 18 more tomorrow if they remain unhatched in the brood stock tank.

Just a side note - reading through about your pair, and knowing that Damsels are generally supposed to start life as females, it would make sense that the one guarding the nest is the male and the one cowering is the female. Perhaps you should hang a section of large diameter PVC up by where she hides...will give her a more secure home.

Matt, I put a second pot in the tank and she has taken up residence there. They are getting along better now though, and I frequently see them swimming together in peace if not enjoyment. I continued to add 10eggs, morning and evening, to the kreisel until I noticed that the other eggs in the broodstock tank had hatched. By then,kreisel Iso and P. crassirostris had bloomed, so visibility was minimal. Yesterday I could not see any larvae, so I thought it had failed. This morning, however, I saw a couple of tiny swimmers with pigmented eyes trying to strike at food. I don't think they can miss, given the amazing population of pods in there. Pods look as dense as a rotifer culture.

If this works I will credit the success to the small number of larvae in the relatively small kreisel. My goal is not to produce large numbers of them, but to get one to 60 dps.

Gave the kreisel a bottom siphon, removing the largest brine shrimp, some more Iso and a small water chonge last night. This morning I saw at least 3 larvae darting for food. To quote Matt, I ONly need one.:-)

If I get them to tomorrow I will have passed the first hurdle, getting them to eat past the starvation time. Then it will be the challenge to get them to meta. They look rather strong tonight. Although they don't have the body shape of clownfish, and they are not big at all (their eye is about the size of the largest copepods they are swimming with) I think I can detect a bulge of dark food just posterior to the eye. Tomorrow will tell.

Meanwhile, the parents are doing some interesting things. Normally, the presumed male has a white spot on its forehead. The presumed female is rather washed out there, and doesn't usually display this. When I get home from work , frequently, I see them in the front corner of the tank, and they both have the the white spot on display. By the time I get their food prepared, they are back to their usual coloring. This evening I was watching just before lights out. They were active in the tank, swimming to the front corner and darting around and going to their hidey holes. Both had lost the white spot, and the male was particularly black in the face. Both fish spent some time vibrating their tails, sometimes near the sand, and kicking up a small storm of sand into the body of the water. In addition, the male, at times, did a swooping kind of dance in front of her, swimming in a U pattern, over and ove again. He also did a little cleaning of the spot on the wall where some of the eggs attached last time. (They were mostly on the pot, but there were some on the wall as well, and by some, I would guess, a thousand or so.) The female does not look gravid, and indeed has never looked gravid, despite the weekly appearance of THOUSANDS of eggs. They are very tiny eggs, and these are relatively large damsels. Just reporting the observations. I have no idea what they mean, but I am expecting a spawn tomorrow, and I hope to catch them in the act, so I can know when they do it...

Judging by the swimming patterns, I have a huge population of apocyclops in the kreisel. I will try to reduce all copepods tomorrow, as they are so dense, they are eating all they phyto, and I fear that they will crash one day if I am not quick enough to replenish.

I did siphon out the copepods that collect on the side closest to the light. I siphoned out 500 ml of them. the copepods were 10/ml in the collection pitcher. ALL PARVO. No Apocyclops. I fed the 5000 Parvo to the pipefish, who liked them very much, thank you. I noticed soon after that I could not find any damsel larvae in the kreisel, so I think it failed, and now several days later, I am sure of it.

Meanwhile, of course, the Damsels spawned again, this time on an algae covered wall, instead of the nice clean clay pots. I almost missed the spawn, as I was not looking for it there. It was well camouflaged. As I scraped eggs to check for maturity, it seems the damsels attached them directly to the filmy algae on that wall. No clownfish-like nest cleaning preparation for these damsels. Just pick a spot, and get busy!
