Fry Count:

| Fry Size: |
1 and 1/2 inches long, approximately, 1-2 mm in diameter. |
| Food: |
to begin: 1/2 gallon of my best Parvocalanus culture filtered, live isochrysis: 250 ml of a dark coffee culture. 2 days later, another half gallon of a different jar of pods, this one containing Parvocalanus and Apocyclops panamensis, filtered and added. Later, rotifers appeared, probably from the store the pipes came from, and what we think is Euterpina acufrons, a harpacticoid that thrives in live phytoplankton. It seems to have been contaminating my Parvo cultures. |
| Feeding Schedule: |
none. pods and phyto added as needed. |
Fry Description:
(Pre Settlement) |
About 1/2 inch long squiggly transparent threads with eyes and heads. |
Fry Description:
(Post Settlement) |
At the settlement start date, they looked to be twice as long as they were when they hatched, but still very thin and threadlike. There is some pigmentation, with a pattern of reflective spots. Settlement is noticed when they have color, and appear to feed off of the bottom and sides of the tank. the one survivor appears to be 3-4 times as long as the day he was born. His body is more filled out and I can find him and see him without a strong flashlight. |
