Do you find that they are as hardy as every place says they are? They say good beginner coral.....I keep my two birsdnest corals in med/high light and med/high flow.
They aren't getting quite as much light and flow as my acropora frags, but they're close.
I'm sure the attached article probably goes into way more detail, but that is what mine have had success with.
Birdsnest Coral requires moderate to high water flow and bright lighting (PAR 300-450) to maintain its color. T5's, Metal Halides, or LED's can all grow Birdsnest Coral when the proper PAR levels are providedI plan to buy one. Someone made a post and rough estimate would be 200 par
