I have a 4 month old 19 gallon with;

Fish;

1 Yellow Watchman Goby
1 3 Striped Damsel

Inverts;

1 little green hermit crab
1 Astrea Snail
1 weird looking hitch hiker crab (never see him long enough to identify him)
1 Brittle Star who was a hitch hiker.

Corals;

1 colony of 4 Cabbage Leathers

My 10 G nano has:
8 lb. fiji premium with unknown sps colony
4 blue legged hermits
1 electric blue hermit
Fromia starfish
frogspawn
green digitata frag
BTA-tiny
Looking for appropriate fish-? small pair of true perculas.
Careful to watch BTA not get too close to SPS and hoping frogspawn doesn't try to sting anybody. I also am about to frag my Colt and a Toadstool which could go in.
