The ongoing saga of the PNG Lightning Maroon Clownfish Breeding Project

So despite two nights of attempted hatching of harvested eggs, I ultimately only got ONE viable larvae out of LxL Spawn #3.  It is in a BRT all by itself.

On 11/7/2014 – the F1 Lightning X Lightning pair threw down another nest…and once again, not on a tile.  I won’t be in town to try trapping or harvesting this nest, so I’ll have to wait for the next spawn. Will update with some photos as I’m able.

Not a lot of time tonight, so I get to be real quick.

Spawn #44 was laid by the F0 pair on late evening of 11/3/2014.  Spawn #43 ended up no hatching much when it was finally set up, but seems to have hatched apparently during the morning.

I opted to harvest 50% of the nest from the F1 Lightning X Lightning pair tonight, the 7th night post hatch, the overnight from 11/3 into 11/4. I used a very simple harvesting technique, using a section of air tubing, inserting the tip section from a 2 ml pipette, which was cut at an angle on the harvesting end.  The eggs were scraped from the back wall while the tubing was siphoning into a specimen cup.  The harvested eggs were added to a brine shrimp hatchery resting in a water bath in a BRT, with a bubble rate of a few bubbles per second.  3 larvae were dislodged from their eggs during harvest…one was viable and started swimming, while the other two appeared lifeless.

It’s the 7th night for Spawn #43 which was spawned on 10-22; we’re on the night of 10-29 going into 10-30 now; there wasn’t any noticeable hatch on the tile over the 6th night (I left it with the parents yesterady)….it will get pulled.  This is what Spawn #43 looked like when it was laid fresh on 10-22…I should also point out this is the first time I’ve taken pictures of the F0 original wild pair of Lightning Maroon X White Stripe PNG Maroon Clownfish.

The larvae from spawn #42 that are still alive have largely settled out…it was a small group, but I’ll find a way to work with them.  More importantly, it looks like LM X LM Spawn #2 might be over…I have not found any larvae in the BRT, so one more look, I repurposed  it for Spawn #43.  The eggs got the usual dip in H2O2, but started hatching during it, so they were moved straight into the BRT with 8 gallons of broodstock water and a few ML of RotiGrow Plus (only thing I had thawed…it’ll be fine for the first 24 hours and by that point I’ll have RotiGreen Omega up and running).

The most frustrating news is arguably LM X LM Spawn #3.  So..to recap.  Here was the first spawn:

F1 (Lightning X Lightning) first spawn for the Lightning Maroon Clownfish

 

So…I took some proactive steps and tiled the back wall of the tank.

This was LM X LM (or LxL if you prefer) Spawn #2 on the first attempted hatch night:

Yeah..that gray patch on the side..those are the eggs…

So that didn’t turn out obviously…so I tiled the side wall as well.

Here is Spawn #3, laid on 10/27/2014:

The internet shorthand FML seems somehow appropriate. Clearly the pair is flipping me the middle fin.

 

It’s been a few late late nights waiting for results on the Lightning X Lightning pair’s second spawn. Given that they had either spawned on Thursday, Oct 16th, or Friday, Oct. 17th, and going off of their parents 6 day hatch window, I set up their tank on the evening of Wednesday, Oct 22nd, to prepare for a possible hatch.  This made sense given that it would either fit into the 6 day window if the eggs had been spawned on the 16th. No hatch was observed. On Thursday night, Oct 23rd, I encountered a very small hatch around 3 AM, a solid hour after lights out.  But, nothing furhter happened, so the 10 or so larvae I had snagged simply sat in the snagger for the next 24 hours.  And now, Friday night, the 24th, going into Saturday AM, it’s now just shy of 4:00 AM and I just finished “putting away” around 50-100 larvae from the F1 Lightning X Lightning pairing.  I snagged them with the Vossen Larval Snagger…ultimately most totally bypassed the snagger, so I had to set up a LED crank-charge flashlight and manually attract the larvae to it. I also had to really crank up the flow rate faster than I was comfortable with, but if I hadn’t done that, I watched as most every larvae would swim back out of the trap once it realized what was happening.

I gave LxL Spawn #2 a very weak dosage of RotiGrow Omega (yes, I know this is not ideal, but I need to thaw out some new RotiGreen) and placed a half gallon’s worth of SS-strain rotifers (because I have those going now as well, thanks Mike) along with roughly 4.5 gallons of broodstock water in a BRT downstairs. Now we wait. Knowing how these fish tend to color up quickly, as long as I don’t massively screw up, we should get an idea of what’s going on very soon…eg. within 30 days.

The larvae from Lightning Maroon Spawn #42 did not do well despite what appeared to be a solid hatch on their second night.  I’m guessing no more than 6 are still viable.

Back on Wednesday, Oct 22nd, 2014, the Lightning Maroon and her mate threw down Spawn #43.  A beautiful nest.  I have a lot of photos in the camera to post, but I’m still recovering from two back-to-back laptop rebuilds, so pictures are just going to have to wait for now.

Lots of little updates

Spawn #41 was left to go for itself because the Lightning X Lighting Spawn #1 took priority.  Unfortunately, by the time the eggs reached the anticipated hatch night, Wed, Oct 8th, there were only 7 eyed up eggs left.  I attempted to harvest them by using a rigid air tube attached to a flexible tube to scrape and siphon them out…this broke one egg but the rest went through intact.  By the next morning in the incubation cup (a half gallon specimen cup with broodstock water), the eggs were dead.

So back to the F0 Lightning X White Stripe pair; Oct. 11 they laid Spawn #42, and tonight, Friday, October 17th, 2014, I pulled the eggs and gave them the typical H202 Bath..about 11 minutes in, we (Paul Whitby of HighDefCorals is in town to speak at our club) noticed that larvae had begun to hatch, so the dip was ended and I placed the tile in the cleaned, readied 6 gallon BRT which had 5 gallons broodstock water and 1 gallon new water.

In other news, the Lightning X Lightning pair put down their second spawn somewhere between 5 PM on Thursday, Oct 16th and 4:30 PM Friday, Oct. 17th. It’s a much larger nest, which was expected. Despite having basically tiled the entire backside of the aquarium, the pair thwarted my efforts by spawning around the corner in a tight area of black plastic background. I don’t know when the proper “harvest” date will be for these fish; I’ll like try my Vossen Larval Snagger this time around. But I also know that I’ll be putting even MORE tile into their tank now ;)

So yeah…October 2nd, I’m just walking by the tank and I see this…

F1 (Lightning X Lightning) first spawn for the Lightning Maroon Clownfish

We are about to embark on the next exciting chapter of the Lightning Maroon Clownfish and genes.  My hypothesis is that the Lightning gene is partially dominant or dominant. The offspring from this spawn, if successfully raised, will yield important answers that may shed new light on the genetics at play. Will we see something NEW come out of this? Well..I certainly hope so and it looks like I’ll get to name it!

Let’s give that a closer look:

Yup, one of those quick little posts…9-29-2014, Lightning Maroon Spawn #41 was put down…and we’re back on the “slanted” tile instead of the vertical one.

And alongside, the loaner pair of A. melanopus from Mike Doty also spawned on 9-29 as well…time to get me some MBI points!

That is all…

White Stripe Spawn #3 seems to have hatched earlier than expected.  I was looking at the tank on Saturday, 9-13, which would’ve been the day to pull the tile, but the eggs were already gone.  So they may well be on a 5 day schedule?!

Meanwhile, Lightning Maroon Spawn #40 was laid on 9-10-2014.  I’ll be out of town late this week, which means I won’t be able to properly tend to baby lightning maroons.  So this batch, like the last, will be left to hatch and move one.  I believe I’ll be in a good position to deal with Spawn #41 if the fish are back on schedule.

That’s all.

I skipped worrying about the hatch on the last spawn…we simply have too much going on in our lives at the moment to effectively start rearing a batch of clownfish this week.  Meanwhile, on 9/7/2014, the White Stripe Maroons, the unrelated F0 pairing, put down another nest, but small.  I’ve yet to see a really large nest out of these guys, and their spawning is not consistent yet.  I will try to raise this batch so I have outcross material…and down the line I may finally opt to split this pair up to make three foundation lines of Lightnings in my fishroom.

That’s all!

After a lot of downtime, the Lightning Maroon Clownfish F0 pair settled back in and put down a SMALL nest yesterday, in the afternoon of 8-30-2014.  This after a couple tile house collapses and such, combined with a diet change, which put them off for a few weeks.  Basically, I accidentally thawed the Shrimp/Scallop mix I had been making, and have yet to find the time to remake it, so the fish have been only on pellets (Thera A from Spectrum and Ocean Nutrition Formula 1).  Seems pretty apparent to me what happened here…
