Breeding Marine fish?

[SeaHorse_Fanatic]

I have a breeding pair of Marine Bettas but they laid their first and only batch of eggs in my main display a year ago. I have a friend who regularly raises live rotifers, bbs, and phytoplankton who lives nearby and if he sets up a proper breeding system for the bettas, I may try to catch them out and let him have a go at breeding and rearing the young.
