Spawning Details Date of First Spawn: 6-15-2013 (the eggs were first noticed on this day, however, it was clear that they had been spawning for at least several days, if not longer at that point)
Spawn Time of Day: Early morning, I believe. Between 6 and 8 AM I see interaction between the male and one of the females that looks like spawning

Hatch Time of Day: After lights out
# Days after Spawn: 11 or 12th night after spawn (at ~78* F)
Larvae Description: ~3mm, thin, and black. Very easy to see due to the pigmentation.
Consecutive Hatch Dates: 6-20-2013 (~15-20), 6-21-2013 (1), 6-22-2013 (2), 6-23-2013 (10), 6-24-2013 (5), 6-25-2013 (7), 8-8-2013, larval run that resulted in one reaching meta hatched on 9-25, 9-26 and 9-27-2013; 12-30-2013, 12-31-2013, 1-1-2014, 1-2-2014
Larval Tank Details Temperature: Aim for ~75 F using a germination mat
Size of Larval Tank: 1 gallon fish bowl
Substrate Details: None
Other Tank Decor: None
Filtration Details: live phytoplankton
Lighting: Fluorescent strip light
Lighting Cycle: 24/7
Water Changes: daily or every other day to remove prey items
Larval Feeding Details Food Types: L strain rotifers for the first several weeks, nhbbs shrimp added around day 4 or so (at least that's when a few have started to eat them), apocyclops and euterpina as they are available
Feeding Schedule: continuous with rotifers, add nhbbs at least twice daily
Metamorphosis/Settlement Date of Settlement Start: 10-15-2013, 1-19-2014
Days after Hatch: 19,20 or 21 (not positive which exact date this one hatched from since several hatches were combined). In my second attempt, settlement happened between days 19-22 (once again, several day's worth of hatches were combined, so exact settlement date is unknown)
Date of Settlement End: 1-21-2014
Description of Fry: Begin to cling to surfaces more than swim in the water column. Black with brownish stripes across the body that turn to black and white-ish stripes a couple days later. The head widens a bit and a spot starts developing on the tail similar to the spot the adults have. Also begin to do the same tail curl the adults do when clinging to the surface. The snout begins to elongate slightly after clinging starts and the stripes that run the length of the body begin to fill in.
Grow-Out Tank Details Temperature: Size of Grow-Out Tank: Substrate Details: Other Tank Decor: Filtration Details: Lighting: Lighting Cycle: Water Changes: Size at Transfer: Age at Transfer: Grow-Out Feeding Details Food Types: Feeding Schedule: Additional Information (No Pictures or Videos in the Section Please) Miscellaneous Information: Males are more difficult to find than females. Of the twenty or so fish of this species I have seen in the LFS or ordered online, I have only seen 3 males. You can differentiate males from females based on the shape of their snouts. Females have long, skinny snouts and males have short, wide snouts.
You will be required to provide photographic or video evidence in this thread of each event submitted for the MBI Program.
If your thread does not contain these photos the MBI Committee will not be able to approve your reports. PHOTOS AND VIDEO S MUST BE PLACED IN ADDITIONAL POSTS, NEVER IN THE FIRST POST IN A JOURNAL.
