I've got a 20gal setup with about 11lbs of live rock and live substrate. (Considered micro in the world of saltwater tanks) I won't get into too much detail though if there's no-one else who knows a lot of the terminology, but I'm willing to chat about it if you want to know more.
The tank has cycled out the diatom bloom and currently the primary algae are coralline and hair algae.
The current inhabitants are:
Fish
3x True Percula (Clownfish)
1x Yellowtail Damsel
1x Yellow Watchman Goby
1x Green Clown Goby
1x Lawnmower Blenny
Invertebrates
2x Astrea Snails (one has a fan worm on its shell)
2x Nassarius Snails
1x Turbo Snail
1x Skunk Cleaner Shrimp
1x Sexy Shrimp [EDIT]No longer MIA... just hides during the day, probably needs some buddies
1x Flame Scallop
1x Black Sea Urchin
5x Asterina Sea Stars
1x Small Pink Bubbletip Anemone
1x Small white tentacled/pink stock actinaria-type anemone (I want to say it's a long-tentacle sea anemone.)
& a few random sea fans, tube worms and sponges in the live rock
