The Lightning Project

The ongoing saga of the PNG Lightning Maroon Clownfish Breeding Project

I am still owing the world a full post, but in the interest if simply keeping you all relatively updated, here’s some short tidbits.

Based on an egg photo count, there was 310 eggs on the tile and all hatched.  There have been some larval losses, but that is to be expected.  Mike Doty did an excellent job watching the babies in my absence – plenty of live larvae when I returned from Boston this past Sunday, July 1st.

Since returning, larval maintenance has been a study routine of upping the water volume with drips of pre-mixed saltwater (for those who will ask, I am currently using AquaCraft’s Marine Environment – they donated a palette of it for Banggai-Rescue).  The SG is probably running around 1.021.  I am using Reed Maricultures RotiGrow Plus to culture my rotifers, and using their RotiGreen Nanno for greenwater (I may have preferred the Omega variant, but Nanno is what I had on hand).  I’ve been dosing RotiGreen and CloramX (a solution mixed from the powder) at roughly a 2:1 ratio, and averaging 30 drops twice a day now on the BRT. I have been harvesting up to 4 gallons of rotifer cultures daily (2 in the AM, 2 in the PM) to keep rotifer levels up.  As of tonight, we are at basically 6 full days post hatch, so I introduced the larvae to their first taste of APBreed TDO (Top Dressed Otohime), Size A (smaller than the A1 I’m more normally accustomed to using).  All is going well with these larvae, and I look forward to settlement soon.

The Lightning Maroon herself continues to be a problem…the Foureye has been removed for a while now, the Maracyn + Maracyn II treatment was long since done yet low level bacterial problems persist, most recently some very light markings on the male’s face, and then I found what looked like an enlarged light area on the leading spines of the left pelvic fin.  These fish just can’t get a break.  I am continuing to work with Dr. Kizer on some alternate ideas, as we’re really ruling out all the normal causes at this point.  Me, I’m stumped.  Without diagonistics, I think it’s fair to say that Dr. Kizer can’t really offer any other insights either.  We may try yet another antibiotic course, another one dosed through the food, that seems to be where we’re heading.  But I’m also thinking I don’t want to overreact either, so most likely we will try to have the prescription-based feed on hand, ready, should another large-scale problem crop up.

So not sure how much I’ve conveyed, but the jist was that I had an artificial incubation hatch last night.

Once hatched, I tinted the water (about 5 gallons of broodstock water) green with Reed Mariculture’s RotiGreen Nanno (a frozen algae paste specifically made for use in greenwater technique).  It took about 20 drops.  I added 10 drops of Chloram-X (for ammonia control).  And I sieved 2 gallons of rotifers to innoculate the black round tub.

Mike Doty came over to check everything out, as he is in charge from now until my return from the Boston club’s event where I’m speaking this weekend.

As of noon today, there are likely a couple hundred baby clownfish zooming around.  A quick check of the water showed that rotifer densities were already quite minimal, so another 3 gallons of sieved rotifers were added.

And that’s it – I’ll have to write this up more thoroughly sometime next week (assuming time permits).

Seriously, one baby found hatched in the tank, and failed to collect it.  One more baby has hatched out in the BRT (Black Round Tub), and that’s it!  It’s now 4:00 AM, so I turned on the lights on the BRT, angled it off to the side so that the light intensity is greatly diminished.  The eggs appear to be fine, so my guess is that I was tricked by a couple early hatchers, and the bulk will hatch tomorrow (Thursday, 7 days post spawn).  That’s my hope anyways, but wouldn’t it be just like the rest of this project to only get ONE baby?!  Wouldn’t surprise me in the least.

In a balancing act, I introduced a very light level of Rotifers and equally light dosing of RotiGreen Nanno into the BRT so that our lone ranger has something to do with all this time on his hands.  I went very light to hopefully avoid any contamination that could foul and kill the remaining eggs who have probably another 24 hours to hatch.

I’ve been taking photos, so at some point I’ll post a pictorial recap of tonight’s (and hopefully tomorrow’s) big event!
