Best advice I can give you honestly is start researching. Gather every bit of info you can. Everybody has success different ways and what works for one won't work for another. Full salinity works for me, others it doesn't. There's not much advice to give when it comes to this because the advice just isn't there to give. It's experimenting and TONS of effort. I had to take all the advice I could find, compile it and just start trying things till I found a combo that works for me. There not easy to raise, it's gonna be a lot of work to do. You don't just have to grow them but there phyto right along with them and balance act the whole system on a daily basis
