The Lightning Project

The ongoing saga of the PNG Lightning Maroon Clownfish Breeding Project

On 5/21/2014, initially the hatch didn’t appear so good, but by afternoon, it was clear I had a solid hatch with hundreds in the BRT. I checked the tile, looked like 50% had hatched perhaps, so I let it go in the BRT overnight again, with only ambient light.  THAT might have been a mistake, because this morning, there was no additional hatch, but many of the larvae had perished. Seems like I have a pretty reliable hatching protocol with H2O2 dip and broodstock water yielding reliable results on the first night. Moving the batch for a second night hatch might just be the ticket.  The OTHER interesting thing – I do have to wonder if we have hatches going on during the day. I’ve long since wondered if that could be happening…

On the other front, Mike sent me an update video of Spawn #27.

Looks like I’m gonna owe him a Gold Nugget Maroon from ORA.

Based on my calculations, 5/20 is the night we’re due to first have hatches. Having moved all the fry from Spawn #30 into a BRT “on the system”, I wiped down and drained their BRT, and refilled it with water from the Lightning Maroon’s broodstock aquarium. The tile with eggs (huge nest, 4″ X 2″) was placed in a 0.5 gallon specimen cup with 4 ml H2O2 for approximately 15 minutes, after which it was set up with a coarse airstone for hatching in the BRT. I confirmed that the air is flowing directly over the eggs at a moderate clip.  This *should* be a good hatch if I’ve done things right.

Side note on spawn #30 – ultimately the split was a nice dice roll – 8 Lightnings and only 3 White Stripes.

As of 5/13/2014, there were two fish from spawn #30 who had yet to undergo metamorphosis; the rest had. Trying to avoid past issues of small groups doing well and then just dying randomly, I selected 3 lightning juveniles and moved them into an empty black round tub that’s running on the larviculture system.  When 5/14/2014 came around, and those 3 test subjects remained alive, I transferred over 3 more Lightnings and one White Stripe offspring.  This leaves 1 White Stripe, 1 Lighting, and 2 unsettled juveniles in the larviculture BRT as of 5/15/2014.

In other news, the Lightning pair put down Spawn #32 on the slanted tile sometime in the afternoon/evening of 5/14/2014.

Then, there is the mystery.  I don’t recall what spawn these offspring are from at the moment, but I had a small group of 5 growing up in a BRT; what amounted to 3 Lightnings and 2 white stripes.  Mysteriously one day, all the Lightnings went missing.  I presumed there had been fighting and jumps, but I never found bodies on the floor. This evening, when doing my feedings, I discovered one of those missing Lightnings sitting on the bottom of a cube tank on the top run. This would seem to confirm that the babies did jump, although perhaps they either went down the overflow or otherwise landed in the sump beneath, and this one apparently made it through the PUMP (WOW) along with a small Onyx Percula (also discovered in the tank today)?!  At least that’s the only possible explanation I have, but wow, I am shocked that these fish would have made it through the pump at all…they weren’t that small!

I can only say this is bizzare.  I have yet to give the sump a more thorough examination tonight with a flash light, but I would not be surprised to find a couple more clownfish hiding in the dark down there!  The Onxy Perc and the single lightning were both placed back onto the Onyx Percula tub for the time being; frankly the Lightning did not look to be in good shape, and I would not be surprised if it doesn’t make it.
