I feed mine my own "fish soup" concoction;
Mysis (used to use brine) soaked in a squirt of CoralPlankton and Selcon. I've been hand-feeding them. Trying to make sure each polyp got some. They seem to like it because their mouths open before they can even get their tentacles out.
So far I think this has worked well since its grown quite huge. The tentacles are super long now, too. I thought about getting some Cyclop-eez but I figure its growing so no reason in changing its diet.
I fed mine every other day just after lights out, like you. Sometimes I miss a day. Although I missed a few this weekend since I was away on a business trip. I'm sure its hungry, you should see how much it can stuff in its polyps. Heh.
