Forgive me if this is a question that's been addressed, but have you looked for any papers detailing the past success of culturing other Dascyllus damsels?

Yes there is one from India, and they have pictures of the juveniles, but I have been unable to repeat their success.

IT's time for them to die again. This time there are at least two in there swimming. I captured one this evening, and he is transparent except for the eyes and the very brown guts. In the past, when I've attempted these guys with abundant Parvo, it has been Parvo of all sizes. This time, I'm adding nauplii each day, so there should be nauplii to munch all the time. In the past, with Parvo, they have all died by day 3, and this is day 5 with Parvo nauplii, and I still have at least 2, so that's something.

I was ready to drain the tub for the July 3 hatch, when I noticed a bright eyeball swimming. I think I have at least one survivor at 6 days! I witnessed this several times this morning. This is a breakthrough for me. More P. crassirostris nauplii and live Iso added this morning. We live to hope.

Its definately a larvae swimming, hunting, and striking, and not an air bubble or a floater, or a large copepod. Yay, day 6! Tomorrow is another day.

Day 7 morning, and I have at least one swimmer! Skimmed some bubbles off the surface, and added about 200 ml live Iso. I checked the copepod population in the BRT, and have a decent amount of day 1 nauplii and some adults, so the naups I added a week ago that did not get eaten, must have reproduced. I decided not to add more at this time. The larva presents itself as a bright dot, larger slightly than the copepod bright dots, and not being pushed by the flow, but swimming independently of it. If it gets close to the surface, I can detect a hint of a body, but at the turbidity of the BRT, that's all I get for now. When it dives below the half full level of the BRT, I can't see it at all. No point in taking pictures. Its motion suggests hunting and striking at prey. I look forward to the possibility that it will grow.

Day 8 evening. Just spent an hour searching the tub with a flashlight. Mainly frustrated, but I could not look away until…I found it. Still swimming, striking, a definate larva. The tub is now an official Parvo culture. I'm going to have to thin it out. The pipefish will love it. Unfortunately, during the search, I thought I saw a hydroid, so panacur treatment tomorrow.

Day 10: I couldn't find hydroids today, so I did not treat with Panacur. I search for the Damsel larva twice daily. It's actually getting harder to find. The copepods glow more brightly under my flashlight, but the Damsel has a glow that is about 3 times the size. It is very hard to detect the body. The glowing part is roughly triangular, and I think it is just behind the eyes, which seem black. Today, I gazed upon it for almost a whole minute, and caught glimpses of body/tail, but I can't tell how long it is. It seems a bit wider than it used to, when viewed from above, which is the only angle from which I can view it. Should I put tonight's hatch in the BRT with it? It might help with the copepod population explosion. And I might get a few more damsels through, or it might crash the whole thing. what to do, what to do...

Didn't take the hatch, it will be better to leave the lone larva to its own devices, and I'm going to MBI next weekend, so I don't need the complications. I'll just thin the parvocalanus.

Yesterday I caught a fleeting glimpse of the tiny larva in the morning, and couldn't find it at all in the evening. This morning I searched and searched, and was about to give up and go to work, when it appeared amonst the copepods. Now it has 2 black spots on its body, which I can guess is why it is so hard to find in the BRT. The good news is that it appears to be growing and new pigmentation must be a good sign. Today is Day 12. By the time I go to MBI workshop, I hope to have the copepod population down significantly, and set up a peri-pump to keep the Isochyrsis brown water refreshed. When I get back it will be Day 18, and meta may not be far away! I sure hope this puppy grows significantly in the next few days. Bending over a BRT with a flashlight is a pain in the back…. Anyway, I am excited!

Congratulations Kathy - hopefully this one will keep going. I am about to get some BRT's set up and was wondering if there was any benefit in fitting a white base to the bottom of the BRT? I was thinking some plastic 'cutting board' material or similar? Would this aid in locating the larvae?

This evening (DAY12) I was able to capture the little guy in a plastic cup and get a not great picture of him: Sorry for the quality, but it was the best I could do given that I do'nt want to stress him out taking his picture… The eyes are dark, and the brain region, and a spot further down. I don't know what the diagonal projection is, but I guess it will become clear with time and growth.

I once tried to paint the bottom with Krylon white, but it didn't hold tightly, and eventually, I just scrubbed it off. I don't think it helped with visualization even when it was intact.

How is it behaving? Still pelagic, or settling?

Good question. Still swimming around, but even my clownfish didn't go benthic. I guess I should put a piece of pipe in there...

Looks a little fishy to me! Should be interesting to see the difference when your gone a couple of days for the conference.

It still has a lot of transparent parts. I'll wait to see what happens before calling it meta... One thing is for sure. BRTs are great for growing lots of copepods. I've been pulling out 2-3 gallons of the 10 gallon culture each day, and it hardly looks different. Thick, it is.
