Let me explain to you why I'm SO excited about this. First off as you may already know, corals primarily reproduce ASEXUALLY, in captivity. They're cloning themselves as they grow.
In the wild, they reproduce asexually via growing and also SEXUALLY through the combination of gametes. This rarely occurs in the Aquarium. There are a ton of people who set up their tanks with a huge focus on promoting coral sexual reproduction, i.e., through the release of gametes. People change their light cycles, temperatures, moonlighting schedule to match the natural cycles of the seasons to try and encourage corals to get their sexy on. Though most of the time, the corals just don't feel like having sex in our tanks!
By the way the other cool thing about Sexual Reproduction is..........GENETIC RECOMBINATION! Variation in the phenotypes! New colorations and patterns!
Well it happened in my tank! And I'm so stoked to watch these guys grow and get their different colors.
In July, through the Merith Group Buy we had, I bought 4 Rockflower Nems and added 2 of them two my tank. The yellow/red one and the striped green one. The two nems from this group buy were joined by the two rockflower nems already in my tank.

I'm spotfeeding some corals and I noticed this little red dot on the left side of my tank. I think "wow that would be cool if it was a rock flower nem baby". I look at the rock structure on the right side of my tank and see two more of these little red dots on the rock. I'm thinking "wow what are these things!?"

After lights out, I looked at my rockflower anemone rock with Jon's Blue LED light he gave me (thanks again Jon!) really quick to check on my Adult Rockflower Anemones to see SO MANY ROCK FLOWER NEM BABIES!
I've counted 25 babies so far. Most of them are located near the parents. I've only seen 4 rockflower anemone babies attached on the rock structure. There are green center ones and red center ones.
Often times you cannot see the babies because they are covered by the adults. Similar to how you might be surprised to find a jawbreaker baby underneath the adult. I'm speculating right now but I feel like they do not need that much light compared to the adults. I will be spot feeding them mysis/brineshrimp debris.

My Thoughts on their Reproduction
We think the baby nems are anywhere from 2 to 5 weeks old. I'm also noticing that the rockflower anemones are only located in areas where I did not vacuum clean the sandbed I think I sucked up most of the other ones in my last water change
It's said in the Reef2Rainforest magazines that Fall is about the right time of the year when they reproduce.
So I feel like my tank had just the appropriate conditions for them to spawn.
What I think helped with them spawning
Water Parameters:
Alkalinity 7.0
Calcium 400
Salinity 1.029 (ouch! need to lower this)
Nitrate Dunno
Phosphate Dunno
Here's a video I found online of what they look like when they spawn. If you look closely, you can see one of the anemones releasing a white milky substance into the water.

What I think helped with them spawning
- I feed them mysis/brine.
- Mainly because my sexy shrimp lives on top of them and he's hard to feed unless I blast some food at his face.
- Althought Rockflower Anemones are photosynthetic, they still LOVE to eat.
- My refugium light recently turned on which resulted in a lot of dim Light bouncing back into the tank. I suspect this is acting like a moonlight.
- I regularly turn off ALL flow in my tank at night to look at coral or feed corals.
