Smaller birdsnest coral are very hardy and can do well with medium light and flow. The trick to them and when they become difficult is when the size gets on the larger end(softball, melon) they need more flow. Alot of people lose their colonies for what seems no reason after growing it out from frags. Keep this in mind as it gets bigger.
I love birdsnest! Here are a few of mine.
This is now the size of a tennis ball after I tried to frag it. It was the size of a melon!!!
