It depends on what fish you go with , I keep 12 in my 90 but somehow I managed to over do it with blues , soon as I find some colorful I will swap out a few blues to make room,
don't forget to give allowance for fish to grow , when small it may not look over crowded and you think to yourself I can add a few more , but once they start growing you see you over did it and scratch head as you fell for all of them on which ones to get rid of .
as for corals it all depends on your lighting , I always suggest start with zoa's/palys
and other softies like leathers , once you get used to taking care of those you can start moving up the ladder to
LPS torch , hammers , elegance ect , now after that if you have really good lights you could try your hand at
SPS ,
What ever you choose to do fish coral ect always go slow you don't want to over load the tank to fast as it is new .
this was my 90 build the only difference was I transferred 2 established tanks to the 90 so basically I didn't need to reestablish BB as I used all my existing rocks , filters ect , look forward to see your tank once you get it under way
