They dont look to bad.I see some smaller ones coming up. They like to be fead daily and if they feed during the day your lucky as most as mine feed only at night. Mix the diet up. Marine cusine , cyclops is great and brine. They also like medium to higher flow and as long as they feed with pumps on no reason to turn them off.
I have a few coral i target feed and the ony way to keep the other fish and crabs from stealing there food is cover them with a plastic bowl.I drill a hole on top to insert targeting device and a few holes on the sides for a little movement. Lighting if to high can actually be bad for them.
Heres a coral care site that may help.GL.
