i feed micro vert..its a form of photoplaynton...i add that like every three or four days..couple drops.i don't directly feed it.i rely on the powerhead to bring it food....but it gets most of its food from light..so u don;t really need to feed..
No, it's a Kenya Tree (Capnella sp.)
They are photosynthetic, but will not do well in the long run without fairly strong and variable flow to bring the coral food and wash away debris, algea, etc.
