This first post should be updated regularly to include new information as events take place or changes are made to your system
General Species: Pseudochromis aldabraensis (Neon Dottyback)
Social Structure: Pair
Size of Individuals: Male @ 4", Female slightly smaller @ 3.5"

Spawning Details Date of First Spawn: Feb 24, 2013
Spawn Time of Day: Unknown. Sometime after the lights went out.
Dates of Consecutive Spawns: 2/24/13, 3/6/13, 3/16/13, 3/24/13, 3/31/13, 4/7/13, 4/14/13
Courtship Details: Female was seen in the cave next to the male at one point but I've only seen this once. The mating is pretty rough on the female and the next day she has missing scales and torn fins. The male usually forces the female to stay at the top of the tank where she has her own PVC caves, but as spawning time nears the male lets her spend more time in the open (and lower in the tank) where she can feed without being harassed.
Egg Size: approx 1.5mm
Egg Color: white
Egg Count: possibly 150
Hatch Details Hatch Date: 4/11/2013
Hatch Time of Day: started at 8pm, watched until 8:30 pm, lots of eggs hatched after
# Days after Spawn: 4
Larvae Description: Active, "wagging" tail and swimming in place, occasionally darting quickly
Consecutive Hatch Dates: 3/20/13, 3/28/13, 4/4/13, 4/11/13, 4/18/13
Larval Tank Details Temperature: 79F
Size of Larval Tank: 10g, half full
Substrate Details: none
Other Tank Decor: none
Filtration Details: none
Lighting: screw-in type fluorescent bulb and reflector
Lighting Cycle: 24x7
Water Changes: Larval Feeding Details Food Types: Rotifers (
Brachionus plicatilis (L-type) + RGComplete), mix in very small amounts of NHBBS to start. Increase NHBBS feeding daily until about day 25 where rotifers are stopped and only NHBBS are fed.
Feeding Schedule: keep tank loaded up with rotifers at all times until roughly day 25. NHBBS fed 2x daily increasing daily with number fed.
Metamorphosis/Settlement Date of Settlement Start: Noticed change in behavior on 5/16, slight change in color on 5/17
Days after Hatch: 35 days from 4/11 to 5/16
Date of Settlement End: 5/19
Description of Fry: Fully colored, but tail and dorsal fin started out mostly transparent but color after 5/19
Grow-Out Tank Details Temperature: 80
Size of Grow-Out Tank: 10g tank filled with 8g water
Substrate Details: none
Other Tank Decor: Marco Rocks rubble rock piles
Filtration Details: None
Lighting: clip on LED light
Lighting Cycle: 14 on, 10 off
Water Changes: weekly, 75%
Size at Transfer: just under 1 inch
Age at Transfer: 38dph
Grow-Out Feeding Details Food Types: crushed flake, TDO-A, NHBBS. I only really see them eating the NHBBS, even though they did appear to be eating the TDO prior to settlement. They don't go up to the surface now like they did when they were larval.
Feeding Schedule: 2x daily
Additional Information (No Pictures or Videos in the Section Please) Miscellaneous Information: Tank has several 1" PVC tubes, mostly opened but two of approx 5" length have endcaps. Two more open PVC tubes are suspended from the top of the tank in the rear and provide a retreat for the female, and that is where she spends most of her time except when feeding.
