Breeding Journal, Species: Amphiprion ocellaris "Darwin Black"

Breeding Journal DataSheet for Amphiprion ocellaris "Darwin"
General Species: Amphiprion ocellaris - the unique "Black" form originating from Darwin. Social Structure: Male Female Pair Size of Individuals: Female almost 3", male around 2" Age of Individuals: Approximately 4 years at this time Date added to Tank: Female was purchased 11/2/2006 from a LFS with a partner. The partner vanished on 1-7-2007, and was replaced with the fish that became the current male from RPI stock on 1-14-2007. I believe this male was known to be around 4-5 months of age when I got him. Broodstock Tank Details Size of Tank: ultimately the pair has spent most of their lives in a 6 gallon nanocube. Substrate Details: live sand Filtration Details: stock nanocube filtration Water Changes: roughly 50%, once or twice per month. Water Temperature: 82F Lighting: 2 X 18 watt PC (a Nanocustom's tank) Lighting Cycle: 12 hours on, on timer Other Tank Inhabitants: For a while, they shared their tank with a Yasha Hase Goby. The pair is kept with a Red Bubble Tip Anemone host. Broodstock Feeding Details Food Types: Virtually anything you could imagine...multiple types of pellet foods, frozen foods, squid, cyclopeeze, Rod's Food etc.. Feeding Schedule: At least twice a day, but usually more. Spawning Details Date of First Spawn: 5/8/2008 Spawn Time of Day: early afternoon Dates of Consecutive Spawns: - spawns have been sporadic and random for the past 1.5 years. CourtShip Details: The day of the spawn, the male and female both intensely clean the nest site. Egg Size: approximately 2 mm in lenght Egg Color: orange Egg Count: the first spawn was less than 50 eggs. Largest spawns to date have been several hundred, possibly almost to 1000. Hatch Details Hatch Date: - early spawns did not make it more than a day or two... Hatch Time of Day: # Days after Spawn: Larve Description: Larval Tank Details Temperature: Size of Larval Tank: Substrate Details: Other Tank Decor: Filtration Details: Lighting: Lighting Cycle: Water Changes: Larval Feeding Details Food Types: Feeding Schedule: Metamorphosis/Settlement Date of Settlement Start: Days after Hatch: Date of Settlement End: Description of Fry: Grow-Out Tank Details Temperature: Size of Grow-Out Tank: Substrate Details: Other Tank Decor: Filtration Details: Lighting: Lighting Cycle: Water Changes: Size at Transfer: Age at Transfer Grow-Out Feeding Details Food Types: Feeding Schedule: Additional Information Miscellaneous Information: I originally kept track of this project first on Reef Central - http://www.reefcentral.org/forums/showthread.php?t=963740 Then, updated again when they spawned for the first time, on MOFIB - http://www.marinebreeder.org/phpbb/viewtopic.php?t=2630 For my past experiences, refer to the above threads. As this is a current project, new posts will be made below

I don't remember what date we moved the fish from Chicago to Duluth, but it was around September, 2009. It took until January 8th, 2010, for the Black Ocellaris pair to spawn. The surprising part was the fact that they stopped laying eggs on the rockwork and finally used the tiles! That, and the spawn was massive compared to all others. Still more surprising was that the eggs appeared to go to full term for the first time, disappearing overnight on in the transition from the 17th to 18th. Something must be going right, because today, January 27th, 2010, they laid another, even bigger, massive nest of eggs. My calculations put hatching due to occur the night of February 6th  Here's some pictures from tonight's spawn:

You're killing me with the awesome pics! BTW, I see you're using a single tile. I just switched mine over to tiles but I'm using the "lean-to" set up... Obviously you don't have room for that in your case. I hope mine do nice neat rows like that too.

so Big boo today - The eggs developed fast, they were fully eyed yesterday,which told me they'd either hatch last night or tonight. So after lights out, between 9:00 PM and 1:30 AM, I periodically had the pumps off. I don't know if the pump shutoffs did it, or something else was to blame, but today, the nest is dead and 50% gone. And No Hatch that I'm aware of! GRRR. BTW - I needed to come back and add - strangly, it almost looked as if the pair was going to SPAWN again last night. Female is huge, and they were circling around on the tile. I thought I might end up with a double nest. Something got botched here...and I'm blaming myself at the moment... Matt

This is the nest spawned on the 13th. It turned silver today, 6 days post spawn (Feb. 19th). Based on when it turned, I'm guessing it should hatch tomorrow night, 7 days in. I don't have a functional thermometer on this tank, but I'm guessing it's at least 82-84F. What do you guys think?

Looks nice. My Darwins seem to hatch on night 8-9 but I'm keeping them a bit cooler, ~82°, and pull the tile so that may be slowing mine down.

Well, came home from the Wilco show @ the DECC, having delayed any possible hatch from 9 PM to Midnight now, the lights just went out. I have to say, when we came home, both parents were paying particular interest in the eggs - behavior that I normally associate with hatch night. So I am now camped out, watching things in the moonlight periodically, just to make sure there's no funny hatching business going on tonight!

No hatch has come off (a good thing) so I took a peak with the flashlight just to be sure. If you ask me, something about the eggs doesn't look quite right..i.e. it looks like they're dead? Let's hope that's just my imagination.

Well, maybe the eggs are still alive. Pretty convinced that tonight will be the hatch then..will be watching carefully.

So the eggs weren't dead, and thus begins another stressful evening of wondering IF they'll hatch. I'm guessing they won't, as it's now been almost 4 hours since the main tank lights went out. That forces hatch day to be Sunday, day 8, and more on par with what we might expect. Still...will keep checking in..

Once again no hatch, so this one tonight is the real deal. Has to be! I may pull the tile and hatch them in the larval tank... I really don't want to deal with the anemone catching all my babies....

Pulled the tile tonight at 8:00 PM (lights went out on the broodstock around 8:10) and placed it in a 10 gallon tank which I sterilized (bleached, dechlored, drained, rinsed, dechlored, drained again). About 2.5 gallons of water from the broodstock cube, and another 2 or so of clean new 1.025 saltwater I mixed up around 7 PM. Set it up just as I've done in the past, using the basic method shown to me by Joe Lichtenbert, airstone bubbling up over the eggs along the tile (yes, direct contact). Taped a dark paper brochure over the glass to darken out any external light coming through the glass...

I posted this with my "hatch report" "other info" -> I wonder if in fact I will once again be subject to hatches split over 2 days. Many of the eggs remained unhatched on the tile...I moved things around and left the tile in the tank...will check it tomorrow to see if the eggs are still alive. MOST of the larvae that hatched, when checked after midnight, were found on the bottom of the tank. I added 20 drops of RotiGreen, as well as a gallon's worth of rotifers, and left the tank lights on to hopefully get the weary larvae up off the tank bottom to start feeding. No clue why this happens - it seems to be a regular issue with my clownfish. Will update this report if more eggs hatch on the 9th night. Overall, if I had to take a while stab at this, I wonder if either the parents would've done a better job of hatch, or if I STILL pulled the nest a day too early?! I wonder about the day too early part, because these babies all had nice round stomachs with plenty of "yolk" to consume, yet they're mostly all ending up on the bottom of the tank shortly after hatching??? Pictures are the proof (and this newer camera just SUCKS!)
