Spawn Details

|
Pre-Spawn Behavior: |
No pre-spawn behavior was ever observed
|
|
Spawning Behavior:
|
No spawning behavior was ever observed. Eggs found afterwards were the only indication that something had happened!
|
|
Post Spawn Behavior:
|
In one case, the pressumed male sat on the clutch and guarded it, but ultimately it disappeared (either was infertile and died off or possible was eaten).

Description:
|
Eggs were laid in a small patch that was guarded and was otherwise out in the open. Never found location of the first spawn. There may have been other spawns as well that we just never noticed.
|
|
Location:
|
Again, the one spawn we were able to observe was laid in the open on the live rock. Knowing how other species of this genus spawn, there could have been other spawns in other locations that we didn't know about.

Other Details:
|
Ultimately, the pair was given to a friend because they were eating our Knopia (Daisy Coral) and well, my wife liked the coral better ;)
