Fry Description:
(Pre Settlement) |
Pelagic larvae are transparent with 3 glowing dots under the flashlight, and are constantly darting in the water column. |
Fry Description:
(Post Settlement) |
The settled fry cling to the wall, as if resting, occasionally darting out for a swim or to find more food. It's body is opaque and the eyes do not glow as brightly when hit with a beam of light. As of day 23, there is a vague yellow color just behind the head and a row of dots from the back of the head to the tail which could be spinal column. |
