Copepods and Mandarin Dragonets?

[SirCharles77]

I have just set up my 105g tank in the last month. It has a 28g sump and is all set up and working.

It has live rock and live sand, 2 chromis, 3 Kauderns Cardinals, 7 hermits, 4 snails, and a sand sifting star in it. The brown algea is pretty much gone and I am starting to see some coraline algea growing on the rocks.

One of the main fish that I want is a pair of mandarin dragonets.

So my question is when can I expect to see copepods starting to appear? Will they begin to appear on their own? Or do they have to be seeded initially?

Do they need corals of some sort to survive? And once they are started, how can I keep the population replentished? How often do they reproduce?

Basically tell me EVERYTHING you can think of as to how I can get my tank ready for a couple mandarin dragonets.

Thanks a ton.
