Spawn Details
|
|
Pre-Spawn Behavior: |
No extensive courtship has been noted so far. Spawns often occur within minutes of the lights coming on. A female simply enters the male's tile condo. Occasionally, the male will wiggle on the tile near the spawn site, as though to entice a female over.
|
|
Spawning Behavior:
|
Male's stripe changes from yellow to red and he wiggles in front of the female(s)
|
|
Post Spawn Behavior:
|
The female leaves the tile condo and the male guards the eggs (and sometimes eats them)
|
|
Egg Details
|
|
Size: |
~1.5mm
|
|
Color: |
yellowish clear
|
|
Quantity: |
Clutches are small, anywhere from a few eggs to ~40
|
|
Description:
|
Eggs are yellowish/clear when first laid, then as the larvae develop pigment spots can be seen. A couple days before hatch the pigmentation is so dark the eggs look black.
|
|
Location:
|
Rough side of a ceramic tile
|
|
Other Details:
|
Larger hatches may actually be from several females laying eggs on the same day.
This report is not for the first spawn noted, but for the first spawn I was able to track with photographs from the date of the spawn until the date of the hatch.
New eggs are laid nearly daily by one of the females in the tank. Sometimes it is only a few eggs, sometimes more than 20.
