Great pic! Isn't this an awesome hobby? Look at them already knowing to use the urchin for protection. I love those little guys. I think I am going to get a couple for my tank when it is ready for them.
Hey reeferdude:
Start off by reading the articles here, and it pretty much describes the how-tos.
I will recommend you do an online search as well. There are prolly about 10 article on banggai breeding which all have aslightly different take.
Lastly i will recommend my forum on fish breeding we discuss banggais all the time (and lots of other fish as well)
