In the back and center you can see my pair of
Regal Angels starting their courtship activities. They
are producing eggs on a nightly basis at this point.
My fish begin their spawning activities after
most of the lights have turn off for the night, at
approximately 11:00pm. For this reason it is tough to get a good image
since the lighting is limited. The regal's spawning dance is very similar to
that of my pair of bicolor and flame angels, which are producing eggs and
larvae. Unfortunately they don't survive more than seven days. I
also have a pair of purple tangs producing eggs in this same reef tank.
I hope to include more photos of the other spawning fish. Movies

Coral Spawning Event:
The
other night I was blessed with a spawning event.
About an hour after the lights had been off I came back to one of my tanks
to check on something. When the lights came on, my eye caught what I first
thought was detritus in the water column. As I looked closer I saw what
resembled cherry red almost sphere shaped eggs all over the branches of my
Green Bali Slimer (Acropora yongei). The fish where consuming the eggs
after they woke up enough. The coral continued to expel eggs for about 30
to 45 minutes.
I wonder how many times this has happened with this one coral or other
corals in my systems? I have witnessed my Pink Polyps (Zooanthids) and
Colt coral spawn before, but this is the first time that I see one of my
SPS going through a spawning event. Click

This coral was
given to me by a friend almost two months ago since it was starting to
bleach at around the second week that he had it. It recovered and
colored up nicely in my system so about four weeks back I fragged it about
a half dozen times. The tips had already healed and had about 1/4 -
1/2 inch of new growth since. All together she has probably been out
from the wild reefs about two or three months.
This coral is kept
in my grow-out system located in my garage. The lights are on a
reverse daylight cycle to control the heat problem during the day as well
as power demand on the house circuit. On that morning, at around
10:00am when I turned the lights back on after they had been shut off for
about two hours I found the coral had begun to release it's eggs.
Remember that due to reverse daylight cycle, as far as the coral was concerned
it was two hours into the night. The event lasted less than an hour
from when I caught it. I don't use any moonlights or try to match
the light cycle to the sun's seasonal cycles. There is no light coming in
from out outside either during the day or night since the garage has no
windows. I don't deliberately feed my corals. What ever they
obtain is from frozen fish food when I feed my fish or available plankton
from system.
