General
Species: Sansibia sp. "Blue"
Social Structure: Colonial
Size of Individuals: Small polyps
Age of Individuals: Unknown
Date added to Tank: January 2010
Broodstock Tank Details
Size of Tank: ~480 gals.
Substrate Details: Sand
Filtration Details: Rarely skimmed, algae removal, snail removal as a form of nutrient removal
Water Changes: ~100 gals./week or so
Water Temperature: 80-82
Lighting: Metal halide, broodstock are under 250W 20,000K
Lighting Cycle: 11am-11pm
Other Tank Inhabitants: Aiptasia (sigh), Tangs, Clowns, Wrasses, Grammas, Gobies, Blennies. The works. Ricordia.
Broodstock Feeding Details
Food Types: Mostly a homemade frozen fish goo. Fresh marine ingredients blended together.
Feeding Schedule: Tank fed 3x-4x/day. No target feeding.
Spawning Details
Date of First Spawn: 14 April 2010
Spawn Time of Day: Late afternoon/early evening
Dates of Consecutive Spawns:
Courtship Details: Usually with brooding corals, male polyps release sperm to the water column, females take the sperm in and use it to fertilize planulae in a section of the inside of the polyp. Some corals will brood in the tentacles, but I don't think that's true here. On the day of spawn, planulae will stage out to the oral disk, and will later release.
Planula Size: Unknown , pretty small
Planula Color: White
Egg Count: Unknown
Hatch Details
Hatch Date: Unknown
Hatch Time of Day: Unknown
# Days after Spawn: Unknown
Larvae Description: Normally, planulae (which look like a grain of rice with cilia) will swim for a while, then will descend and start "tasting" the substrate with chemoreceptors. When the planula likes the way things taste, it will attach and then flatten out like a pancake. A primary polyp will arise from that.
Larval Tank Details
Temperature: Same as broodstock.

Food Types: No direct feeding.
Feeding Schedule:
Metamorphosis/Settlement
Date of Settlement Start: See under hatch description above. If the primary polyp is successful, secondary polyps will appear.
Days after Hatch: I didn't see the primary polyp development. But colonies have formed in many places all over the tank.
Date of Settlement End: No real clue.
Description of Fry: Coral colonies look like small versions of the adult colonies.

Additional Information
Miscellaneous Information: These really are _easy_ corals to propagate sexually. Anyone who is interested in beginning to study coral sexuality could do much worse than to start with these.

Cory has really done a good job of documenting the entire process.
