Re: Breeding Journal, Species: Chrysiptera parasema

Here goes attempt #1! The eggs started hatching immediately after lights out. My Vossen larvae trap collected probably 300+ larvae in about 1 hour. I didn't collect any longer as I don't think my brt could handle any more than that anyway. I put the larvae into sterilized reef tank water in the brt for the night. I will add rotifers and greenwater in the morning.

I'm not sure if they are eating the rotifers (yet?). Maybe they don't eat right away? Maybe the rotifers are too big or not attractive? I expected the rotifers to be cleared from the water column by this afternoon, but there are lots of rotifers still in there. I'm going to pull a larva tonight and look under the microscope. Here are a couple pics from lastnight. I took a video of them getting sucked up the Vossen larvae trap too, but I haven't checked it out yet [EDIT: video quality is terrible!]. I'm not sure if anything can be seen.

Ok, well I can't get my microscope to work right now (hard drive is dying on puter) so I had to just use my camera. After looking at them up close, I still have no idea if they are eating or not. I don't think so... Tomorrow I will try to get a pic with a rotifer in it to compare to the larva. I didn't think of doing that tonight. 23 hours post hatch:

That's a bummer, they look cute. Thanks for finding that article, I'm going to add it to the library.

Seems likely. They are probably way too small for rots. Good job catching them, though.
You only need 20 days of food (if these act like sergeant majors). Maybe just order in a couple of batches of copepods and some algae to keep them nutritious?

It was definitely a dread feeling when I saw that.  I see earlier in my thread I thought rotifers were 180 microns, but reading Witt's book I see adult L-type rotifers are 300-340 microns. I think the nauplii hatch around 180 microns which should fit in their mouth, but that obviously has extreme limits.

I have not been able to get my hands on Parvocalanus crassirostrus in Canada. Reed's has them drop shipped, and the company that does so won't drop ship to Canada. My LFS hasn't been able to find any suppliers listing or able to get them from AlgaGen either. I put an email in to AlgaGen lastnight asking if they will ship direct to me, or if they know any LFS or wholesalers in Canada carrying them. If that doesn't work for me, I will be asking some MBI members to help me out.

I didn't see any striking in the larvae tub, so I guess I knew the answer already.  Looks like I also need to use a much bigger larval tub too.

Sorry. I didn't look and missed that you were in Canada. How are the Blades doing this year?
Getting any package across the border either way sometimes (all the time) seems like such a nightmare. I'm a typesetter and I remember back when your courts first enacted your new obscenity laws: It used to take months to get manuscripts (basically stacks of paper) across because the border guards were checking everything. Getting correction pages to and from authors was a nightmare.
From what I recall, there are some folk who make a living having an address on the U.S. side and on the Canadian side, driving packages over the border, and then re-shipping. Maybe that would work if you could find someone?

Most of them were dead by day 3, and on day 5 they were all dead. It turns out AlgaGen with direct ship Parvocalanus to me, and apparently I can get them through ORA (through my LFS) too even though they aren't on ORA's list. Not that I want to encourage my LFS to order from ORA though...

What is the problem with getting them? Are they not allowed to be imported into Mexico or is it just that you can't get anyone to send them to you?

Last week I found the male cowering in the corner of the tank breathing heavily. On close inspection, he had some white thing on his forehead. I wasn't sure if it was parasite or fungal. He was looking terrible, and didn't even swim away from the net. I gave him a Formalin bath to try to help. In the morning he was a goner.
I will try to re-pair the female.

Mindy, look back to Wittenrich's book - I do not think Chrysiptera required copepods (they'll HELP, but they are not required). WE shouldn't make assumptions across genus lines; my understanding is that Sergeant Majors were one of Witt's "nemesis" type fish...one he had to chase a long time before succeeding. C. paresema doesn't seem to be in the same category (eg. look how much more developed they are than Chromis offspring, which hatch as prolarvae).
Good luck with the re-pairing...this is one you should pull off with patience and practice!

Hey Matt. Yeah, you would think rotifers should do the trick, but so far I have not been able to find success using rotifers. Witt's book says about 50% of the larvae show full guts from small-strain rotifers, but high mortality on day 8. Wild plankton tows got larvae to day 20. Witt says there is at least one successful report for each Chrysiptera species and each was using rotifers and brine shrimp. Witt's book also says Chrysiptera larvae are 2 mm at hatching, and I measured mine at 3.6 mm which I find interesting. At the writing of his book, it appears Witt did not have personal success with Chrysiptera species. My LFS hasn't had any Yellowtails in lately, but I will grab one from the next batch.

Yeah, I always was under the impression that Witt had done everything in the book successfully, although looking back on this now, 7 years post publication, it indeed looks like perhaps he didn't personally complete the work with Chrysiptera. Thankfully I know others have.
Looking back, check the Nov/Dec 2009 issue of CORAL - that includes a quick synopsis of a few successful runs with Chrysiptera from the 2000s. Luis of course is well known for his work with Damsels, having done a few firsts IIRC, and copepods always helped (Acartia tonsa, Pseudodiamptomus) and 24 hour lighting seems a critical component to successful rearing in my brief skim.

Thanks for the info Matt. I will check back in my collection of CORAL mags, and see if I have that one. I didn't have any plans for Acartia tonsa cultures, as I didn't think I had need of them. I will be ordering a Parvocalanus crassirostris culture from Reed's soon, I will try that first.

What are you doing with the rotifers in terms of enrichment / gut loading? Perhaps you could make the rotifers "better" than you're currently doing?

I was gut-loading with N-Rich PL Plus. However, the problem I had was the larvae were not eating the rotifers. There were a handful of larvae that had semi-round bellies, but that's it.

L rotifers, I'm assuming? Could you get your hands on S (or SS) rots?
