Breeding Journal DataSheet

I'm planning a new push with these for the new year.

Broodstock Feeding Details Food Types: A seafood medley, blendered beyond recognition and frozen. Also (frozen): Mysis, Nutramar Ova, SF Cyclops, Daphnia, and pretty much anything else I can find gets introduced to them.
Feeding Schedule: 3-5x/day
Spawning Details Date of First Spawn: First verified spawn 5/6/09
Spawn Time of Day: usually ~8:00pm
Dates of Consecutive Spawns: spawns usually 3-4 days apart
CourtShip Details: This can go on for hours. Female gets agitated, swims the tank sampling various algae beds. Male follows closely. Male often displays "flutter dive" behavior with movements of anal vent (exposing orange color) and opening and closing tail fin like a fan very quickly. Female occasionally also show "flutter dive" behavior. When things are close, male "chatters" at females cheek as she thrusts into algae. At spawn, female presses genital opening to substrate, male quickly joins her. Post-spawn, both look stunned for a few seconds and float away from the spawning site on the current. Male then displays wildly as female swims quickly away.
Egg Size: Sorry. I didn't measure them.
Egg Color: Mine were orange-ish. I think this may be diet-related, as Matt's were green.
