zygote2k October 7, 2012 October 7, 2012 Acros are easy acquired weeds as opposed to a good spawning pair of fish. I'd lgive them as much acro as they need if they keep laying eggs...
Jan October 10, 2012 Author October 10, 2012 She's don it again. Now she pulled the polyps off of the side of the same branch, towards the back and laid more eggs. Most of the eggs from the first batch hatched. I took my filter socks off just in case some make it to the refigium. There are so many pods in the tank that the may have a chance at survival. This female chromis has gotten huge, too.
Jan October 16, 2012 Author October 16, 2012 It took about 15 days for the eggs to hatch from the time she finished laying them. She laid two batches. Waited for the first to start hatching, 7 days later. then laid another batch while the first was hatching. I took one of the filter socks off the so that some of the fry have a chance of survivng in the sump.
Jan October 18, 2012 Author October 18, 2012 Now she's laid eggs on my purple whip gorgonia. She laid them sometime between 1:30am and 12:30pm. So today is day 1. She's been clearing the gorgonia for two days now.
Jan October 18, 2012 Author October 18, 2012 The happy couple Their eggs are on the 4th branch from the left
Jan October 19, 2012 Author October 19, 2012 What are rots? Rotifers? This is starting to make we want to go get some rots!
dbartco October 19, 2012 October 19, 2012 rotifers. I would get in trouble for setting up operations again, but it would be cool to try raise a couple past metamorphosis.
Jan October 19, 2012 Author October 19, 2012 So you got me thinking and I found this http://www.reef-geeks.com/forums/aquaculture-breeding-geeks/219-how-grow-rotifers.html If this is all i have to do then I'm going to growing rotifers.
dbartco October 19, 2012 October 19, 2012 trick is really is just getting a good culture of rots, feeding, and keeping the lot from crashing on you. Otherwise, it is a 5 gall bucket bubbling with twice a day nanochloropsis feedings. I "think" chromis larvae are large enough to eat rots. They may be too small.
Jan October 19, 2012 Author October 19, 2012 Where can I get a good culture? You think the larve "aren't" large enough to eat rotifers? They are very teeny. They can be found in a drop of water. The female looks like she's going to bust. She's huge! an egg laying machine. As long as she steers clear of my acro she can stay. trick is really is just getting a good culture of rots, feeding, and keeping the lot from crashing on you.

Jan October 19, 2012 Author October 19, 2012 Does anyone know how to determine the sex of these fish? The only difference I see is that the female is larger than all the rest. how do you sex chromis?
Jan October 28, 2012 Author October 28, 2012 (edited) She's at it again. Yesterday she looked like she was about to bust. Turned lights on about an hour ago and nothing. Just went back downstairs and she laid her third batch. I thought she was done, but I was wrong. She laid more eggs along the gorgonia. I wish I could actually see her laying them. I am thankful that she's not using my acro anymore. Edited October 28, 2012 by Jan's Reef Foods
Incredible Corals October 29, 2012 October 29, 2012 Someone got a yummy snack. BTW, your fish food is awesome! I know you said the last batch had big carrots but my tusk loves the big chunks. Thanks again!
Jan November 1, 2012 Author November 1, 2012 She's an egg laying machine. We now have batch #4. She's left the acropora alone. She likes the gorgonia.
davelin315 November 1, 2012 November 1, 2012 Jan, I am assuming that the females have an ovipositor since they are laying eggs. Take a look and see if you can see a tiny white protrusion near her anal fin when she's getting closer to laying eggs. Not positive on this, but I would assume that if it's not always visible then it would be when it's gravid.
Jan November 1, 2012 Author November 1, 2012 Ahh, good to know! Makes sense. I'll keep a closer eye on her. the only clue I get is when she starts picking at the gorgonia. I'm so tempted to start another tank and attempt to breed. Thanks, Dave. Jan, I am assuming that the females have an ovipositor since they are laying eggs.

Jan November 3, 2012 Author November 3, 2012 (edited) Well to my surprise while Carleton was here this morning my female chromis started showing us how she laid her eggs. Guess what? She's not the big chromis that guards the eggs, she's the smaller one. The large one is the male. What I have observed is that he initiates the mating ritual. He changes his color to black and white stripes and approches her. He then starts shaking his body. She changes her color to black and white as well and shakes back. Then the go to the area he's cleared for the eggs and she lays her eggs. She leaves after she's done and the male stays with the eggs. He tends to them by nipping at and around them constantly. Any other inhabitants get too close and he shakes at them and chases them away. Yes Dave, she has ovipositor. We saw it as she laid her eggs. Amazing!!! Carleton took a video of the event for me. This is the 4th batch. Something has discovered the eggs and is eating them within a day of the chromis laying them. Thank you, Carleton. Edited November 3, 2012 by Jan's Reef Foods
