I also think, that in at least a couple of week after cycling would be better to add snails, shrimps and such. It helps if you have a really live live rock, live live sand, or access to a free or a lowest cost macroalgae or coral frags. In my tanks corals feel better, it there is already a lot of different life forms.
Easy corals, bright colors:
(with alkalinity 8.5-11 dKH, or my mushrooms don't feel good), green star polyps, white xenia, green hairy mushroom (big!), bright red muchroom (likes light), LPS (easy) - bright green candycane, hammers, frrogspawn (the last two sting, so put them downstream from all others), and the big open brain type - bottom left - scolymia (very big and very hardy, comes in different colors).

Algae: blue ball (Ochtodes or Hypnea pannosa, not sure), red fern kelp, red gracillaria, chaetomorpha (noodle algae, harmless), caulerpa (better to keep it in the pocked bag, invasive).
