There is some amazing aquascaping and fish in this thread, you can do a lot with 75 gallons!
I have a 75 in my classroom with two clowns and two Engineer Gobies, plus a lot of really encrusted and algae-ridden live rock.
Since a 90 is just a tall 75,

my 90 has a TSN. He'll be moving into a 110 or a 185 this summer.
