after dark |
Fry Count:
( at Hatch ) |
hundreds |
Fry Count:

| Fry Size: |
around 1 cm |
| Food: |
started with rotifers and greenwater technique. Around 28 days started offering baby brine shrimp. This may have been "too late". |
| Feeding Schedule: |
rather constant given greenwater technique. "tried" to keep food available at all times. |
Fry Description:
(Pre Settlement) |
This species did not seem to have any remarkable or large noticeable change during metamorphosis / settlement. I am not 100% sure that I DID have actual true settlement. |
Fry Description:
(Post Settlement) |
What DID occur that suggests "settlement" was flexion at day 27 or so, followed by the appearance of a black dorsal spot around day 33. |
| Other Details |
| Other Information: |
I made it to 45 days post hatch with this species. Other more experienced breeders of this fish may in fact suggest that I did not hit "settlement", but based on the information at hand, it suggests that settlement occurs at 4-5 weeks, followed by a lot of growout during which the adult coloration would form. It is DOUBLY HARD to tell when settlment / juvenile coloration actually would occur, given that this species as an adult is still transluscent!!!
NOTE that my dates for this report represent one of several rearing attempts I made with this species. This species HAS been reared successfully in captivity...I just didn't quiet get all the way! |
