I use mysis shrimp of the mini size and medium size frozen.For fish and some larger polyp corals the med. small chalices seem to be able to take the minis easier.I also, use
cyclopeeze with a shotgun approach occasionaly.
Nori ,I like the brown and red but use the brown more so ,I think for the tang and some Iodide addition .(I dont like to add chemicals I dont want to test for or think they lack accuracy.)
Black worms are supposedly helpful and may encourage breeding ,so I read ,I dont really know but use them occasionaly.
I like to include something with a blood content I think it may have some certain beneficial plus.
Mmmmm ,selcon I am a firm believer in,its sorta known as the little brother of what commercial breeders use (selco )whitch is definately know for its benefits in breeding but very expensive.So the selcon is imo the next best thing.
I cant think of what else is in my freezer right now.
