sorry, that wasn't very helpful. I was on my way out the door.
with that type of tank, I'd have a nice display of live rock and some hardy non-aggressive inverts, like some small hermit crabs (like scarlet reef hermits), snails and shrimp (like a skunk cleaner or blood shrimp). For fish, maybe an orchid dottyback and a shrimp goby with a tiger pistol shrimp.
You really can't keep a lot of fish in a tank that size. Others to consider: clown goby, pair of neon gobies, MAYBE a sixline wrasse.
What kind of filtration and lighting will you have?
