feed it, feed it, and feed it some more! I would take mine completly out of the tank, into a tupperware bowl and target feed every single polyp at least every week or the skin on the stalk would rise up. Notice the past tense in what I did.

Light will not hurt it, but it does not need it either, so placing it in the light is not a necessity.
