One of the things that have been on my list of to-dos is breeding urchins. Finally got around to it.
Unfortunately, I moved my bright pink male pincushion to my work tank whereby it succumbed for some unexplainable reason. :/
So had to work with a lighter pinkish white male and a purple with white base female.
I wasn't sure which orientation I had before I began...only way to sex an urchin is to go through the process of extracting the good stuff from them.
As luck would have it, i picked a male and female on the first try.
Often an injection of KCl solution is used to induce the spawning. But some species will respond to being shaken (cue music) "...like a pololaroid picture"
Once the urchins start releasing, i placed them upside down in a container of seawater (container credit goes to @ashburn2k) one at a time.
I started with the male first by coincidence since that's what i realized I had with the first urchin I picked. Then my second random pick was the female.
I forgot to take a picture of the male doing its thing but here is a pic of the female releasing eggs into a prepared love potion.
You can see the eggs collecting at the bottom indicated by the yellowish orange coloration. As well as some of the eggs still being spawned.
After a few minutes of contact time after collection, i gave the container a few shakes to thoroughly mix the sperm and eggs, capped it, and let it sit in the tank to temperature acclimate before releasing the contents.
Likely, i will put a small amount into one of my nanos as a backup hatchery.
So, if I am successful, there might be some free pincushions available for supporting members...
