Additional Information
Miscellaneous Information: 1/13/12 was actually the second spawn, the first spawn was found a couple days after the fact so I don't have an accurate date for it. So the 1/9/12 hatch is from a spawn that I don't know the actual date of. I never moved them out of the breeders net in the grow out because they never caught up to the cinnamons and because there is only two of them. I didn't want to risk loosing them from aggression from the much larger cinnamons. somewhere around 2/20/12 I switched feeding from TDO B1 to TDO B2 and that is what they are fed still at 60 DPS.

For the past week or so the male has spent most of the time hidden in the rock work, Female is very aggressive towards me if I have my hand in the tank. These behaviors are new so I think they have a spawn hidden. Hence starting this journal before a confirmed spawn date.

First spawn. I found a clutch of eggs today! exactly where I thought they would lay them, in the center of the back of the rock work, the hardest place to get to.

I ran out of the rods breeders blend about a month ago, I have been feeding them a mix of Hikari mysis, brine and mega marine frozen foods, random feedings of TDO size ep2, arctic pods from reef nutrition and minced krill.

First spawn. The eggs are getting pretty silver eyed and more transparent, I'm predicting a hatch starting tonight and tommow night. I think I found the eggs a couple days after they were laid, as the eyes had already started to turn silver.

First spawn. This is a much better video from the day I found the eggs. Interesting to point out that the female is doing a lot of the care for the eggs, with my cinnamon clowns the female had very little to do with the eggs.

First hatch. As predicted the eggs hatched tonight. Before leaving for work I set the light timer back an hour so the lights didn't go off till around 11pm. Then I had Paige turn the pumps off when the lights whent out. When I got home there were probably 100 babies swimming around. I scooped out around 50 maybe a bit more.

First hatch. video of the hatch, I use my iphone for the videos and pics and it seems to give me better images with videos than pics at least for small fry.
First one is with the light of the camera on and the second is with just the light from the flashlight that I used to lure the fry to the surface so I could catch them. It looks like a black screen with a couple dancing fry.

First hatch. Another thing to point out about this first hatch, as always I wasn't really ready to set these guys up in a separate set up. I had a water change worth of water setup with a heater and an air stone in a five gallon homer bucket as a hodge podge setup. Then when I went down to the basement with a container full of babies scooped out of the tank I found that I didn't plug in the heater. So they went into a setup I have going with a couple of about five day old cinnamon clowns. Not sure how this will work but figured if there was any chance of survival this was it.
