In my 3 gal I had 1 sexy, 4 tiny nass snails, 2 large nass snails, 1 orange trochus snail, 6 tiny hermits, 2 med hermits, 8 different coral frags, and a false perc.
That worked well for 3 months, and now I have doubled the tank size.
I think a clown goby would be best because they are perchers. The perc (like most percs) wanted to swim all day. That doesn't work well in 1.5-2 gal of water.
The sexy shrimp is a must IMO. She romps around and never hides. Very cool.
I have attached pics of mine:
