Nice!
I would add 2 key words (written in blood :))
"Patience" - translate to take things slow, slow as in put 1-2 fish in a 4-5 weeks intervals, let the biology mature (i know it's extremely hard and most people will not follow, but we are talking about live creatures here, it's heart breaking to see them die because of our mistakes)
"Quarantine" - start from day 1 and setup a quarantine tank, store systems infested with parasites and other crap, if you follow advise above, you can easily aclimate and treat new fish in a small (50l) quarantine tank for 3 weeks before moving to the main tank, this will save you A LOT of frustration and money, it's the best investment you would do (iMO doing this for couple of years)
