Breeding Featherdusters
 

Does anyone know anything about featherdusters?
I have noticed in the last couple of days that I have a couple of small Altantic featherdusters in my Invert tank.
I have approx 10 full grown ones as well, but noticed that there are a couple of small ones that weren't there before.
Does anyone know how they breed?
Any info would be helpful.
If i am able to breed them, I will keep a breeding stock of them so i don't have to take anymore out of the wild.
thanks in advance for any info.

They seem to migrate really easily to the walls of my sump, which is now covered in a variety of types.
