|
Hatch Time of Day: |
suspect main hatch 5:30-6 am on 4/27, and premature on 4/25 and 4/26
|
| Where Hatched: |
Eggs had been previously scraped from the rock they were laid on, transported in a soda bottle, and transferred to a brine shrimp hatcher. I sterilized the hatcher using bleach, dechlorinated, tested for residual chlorine, and added the eggs, their water and an air line bubbling fairly briskly to keep the eggs suspended. I also added 1 drop of methylene blue. |
| Eggs Removed Pre-Hatch: |
Yes
|
| Larvae Removed Post-Hatch: |
Yes
|
| Yolk Sac: |
Unable to Tell
|
| # Hatched |
50-100, but nest was shared with another breeder. His hatched same time and method |
| # Not Hatched |
about 15 |
| Larvae Size |
4mm long |
| First Food: |
rotifers raised on RGcomplete, and enriched with isochrysis and RGcomplete. At day 2, added some Apocyclops panamensis. Added more 2 days later. At day 13, added newly hatched brine shrimp, but not much, and every day thereafter. Tried Otoheim A size pellet feed each day starting on Day 9 or 10 but no real evidence of it being consumed. |
Larvae Description:
( Do larvae have eyes, mouth, gut, attracted to light, etc?) |
Eyes, mouth, gut, attracted to light, energetic swimmers, no appearance of yolk sac, but it might be in there. Measured 4 mm long.

Lighting:
|
Marineland LED strip, blue. on rim of tank, otherwise ambient lighting. After a few days, switched to 18 watt fluorescent bulb with reflector mounted just 10 inches above the water, and only for day. I used the blue LED strip at night for the first 12 days or so. Then I used the 18 watt bulb for 12 hours daylight, and darkness for 12 hours night time. |

Lighting Schedule:
|
I used the blue LED strip constantly for the first few days and then and 18 watt for daylight and the LED at night for the first 12 days or so. Then I used the 18 watt bulb for 12 hours daylight, and darkness for 12 hours night time. |

| Other Information: |
Things that seem important:
1. I strongly think that these eggs hatch in the early morning before first light, rather than just after dark as the A. ocellaris do. The hatchlings seem smaller than ocellaris, and more energetic.
2. Metamorphosis happened at Day 16 for Ron P in 2007, and is progressing very slowly, over many days, despite an abundance of food for my sole survivor.
3. My survivor seems uninterested in dry food. He may be harder to wean off live food than ocellaris usually is.
4. We may need to try S-rotifers to start them off, as Marina P and Ron P report that initial die-off is commonly massive.
