They give live birth, I’ve seen the fry in my filter shocks before.
No actually they swim to the top of the tank and release their eggs and sperm in the water column to be carried out into the “ocean” We’ve been reading and researching breeding them but the collecting eggs part keeps being left out of scientific and research papers.

This is a species that took a years of work to crack the code on and even with multiple breeders and competition vs wild caught specimens the price is around $100 and you are by happenstance getting them to a size where you can identify the fry as such and then tossing them out in a filter sock?

Museum of Monaco *appears* to be straining by hand.

Sounds like you have to catch them in the act and scoop the eggs out



The actual release of eggs occurs at a steady pace and I was excited to see them being released. Only after all the eggs were expelled did the pair make a mad dash toward the bottom sending the eggs in a chaotic spiral to the top.

I grabbed a small water bottle and slowly gathered the eggs from the surface of the water. Using a small flashlight from below, I could see the eggs as tiny translucscent spheres. Some were clumped together in long chains while others were spread singly. After about 15 minutes I was confident that I had gathered every last egg. I plugged the filters back in and immediately rushed the eggs off to my lab at Florida Tech. I was excited. I had waited 14 years to buy another mandarin and instead of watching it slowly wither away I had just observed my new pair spawn in a tiny glass box thousands of miles from the reef. What a feeling
