The Lightning Project

The ongoing saga of the PNG Lightning Maroon Clownfish Breeding Project

I let Jake Adams break the news on ReefBuilders, sending him shots in the late/earlier hours (depends on your frame of mind).  I’m quoting an excerpt from Jake’s great writeup from ReefBuilders here, because he really presents an objective view.

Even though the maroon lighting maroon clownfish was paired with a related Premnas biaculeatus from Papua New Guinea, we don’t think anyone really expected to see expressions of the lightning pattern in the first generation of the lightning maroon’s offspring. All observers of the lightning maroon project who know anything about mendelian genetics realistically thought that we might see some traces of the lightning pattern in the second, F2 generation of lightning maroon clownfish once they were back-crossed with each other a bit. However, for Matt to observe the lightning pattern in his very first batch of offspring from a half-cross of lightning maroon but full cross of PNG maroons clownfish must be very encouraging…

Since my last update, I DID opt to start feeding brine shrimp nauplii.  They are being rinsed well.  I’m using 16 month out-of-date decapsulate eggs from SeahorseSource.com / Dan Underwood, and they’re still hatching great (I keep them stored in my fridge).  I’m doing daily water changes, occasionally siphoning the bottom, and I’ve been using nothing but Marine Environment salt by AquaCraft (thanks Mike Del Prete – who contributed enough salt to last me and the Banggai Rescue project years).  I also started offering the APBreed TDO A1, as well as older Otohime A I had on hand from Reed Mariculture.  I cut way back on the RotiGreen Nanno I was adding; basically just 10 drops or so once or twice per day, just to keep the rotifers in there from dying en-masse.  I am currently trying to weed them out.

These photos (and the video at the bottom) were shot after midnight, so technically this morning (7-9-2012, but almost 24 hours ago now).  This puts these larvae/juveniles at 10 days post hatch, and most have gone through settlement. I have included multiple variations / crops / zooms of most photos so you can get a sense of scale and overall view, as well as the maximum zoom I could give you.

MORE TO COME….

8 days post hatch.  To brine, or not to brine, that is the question.

First noticed this at roughly 1:30 PM on July 7th, 2012.  Dare you to hold your breath…
