Beginner Marine Fish, Breeding

[Matthew37]

I'm looking to try my hand at marine fish breeding, I have experiance with FW fish and bivalve culture.

What do you guys suggest?

I was thinking Banggii's or Neon Gobies? Or perhaps Lsymata shrimp?

I'm just setting up a small system, right now planning a 15G set up for the spiecies I will be breeding. And I'm going to be purchasing algae paste for culturing the rotifers. Also are there any secrets for rotifer cultur? I have been reading many differant artitcals on marine fish propagation, and was wondering if there are any "secrets" that anyone has discovered to make life easier?

Thanks for the help
