Corals... I am sure this has been asked a million times before

these types of corals require regular feedings to survive. water quality would have to be monitored closely.

you can also go for non-photo synthetic stuff which doesn't require lights. Like a suncoral (LPS) or Feather Duster Worm.

zoas and more zoas. Very forgiving and if you purchase the right ones, they can make your tank look phenomenal.

GSP is green star polyp. On my 29 with a 96 watt power compact I kept Wesophyllia, Slimmer, and Monitpora. I changed the lamp every 9 months. Of cousre I also had a baby clown trigger. Kept it going until he out grew the tank and I got bored and split everything up.

button polyps, zoas, star polyps. LPS possibly a hammer coral but it will probably grow really slow, none the less it looks really cool.
