|
Hatch Time of Day: |
1-2 AM
|
| Where Hatched: |
This is rather complex. First hatch was the night of the 27th into the 28th, but only yielded 2 offspring. The bulk of the hatch occurred the night of the 28th into the 29th, just after midnight again. |
| Eggs Removed Pre-Hatch: |
Yes
|
| Larvae Removed Post-Hatch: |
No
|
| Yolk Sac: |
Yes
|
| # Hatched |
310 |
| # Not Hatched |
0 |
| Larvae Size |
3 mm? |
| First Food: |
Rotifers grown with RotiGrow Plus, kept enriched with RotiGreen Nanno in greenwater technique. TDO A1, and Otohime A added starting day 7. Brine shrimp nauplii added to routine after 9 days. |
Larvae Description:
( Do larvae have eyes, mouth, gut, attracted to light, etc?) |
very small for clownfish larvae; given the potential I did not put ANY under a micrscope to measure - my estimate is 3 mm, maybe a bit more. Smaller than Ocellaris, maybe comparable to my perculas. Initially it looked like a 100% hatch rate, so I would assume we stated with 310 larvae. |
