Hatch Time of Day: |
found at 10:00pm
|
| Where Hatched: |
I removed the eggs from the main tank and put them in a small specimen container that is probably a quart in volume. I attached the container to the rim of the tank and floated it in the tank water to maintain the same water temp as the brood stock. |
| Eggs Removed Pre-Hatch: |
Yes
|
| Larvae Removed Post-Hatch: |
No
|
| Yolk Sac: |
Yes
|
| # Hatched |
6 |
| # Not Hatched |
roughly a dozen of the collected eggs didn't hatch |
| Larvae Size |
about 0.5 mm wide and 1.5 - 2mm long |
| First Food: |
None, I haven't tried raising these yet. They don't have developed eyes and likely don't have a developed mouth so I think feeding wouldn't start for a couple days. |
Larvae Description:
( Do larvae have eyes, mouth, gut, attracted to light, etc?) |
Its hard to tell without a microscope with a scale but the best I can say is the larvae are about 0.5 mm wide and 1.5 - 2mm long. They have a large egg yolk still visible, there eyes are not developed, there pretty good swimmers avoiding the pipette. They are mostly clear with some spots that with the naked eye look dark but in the pictures with the flashlight on them they appear almost silver or white.
