Here are some new coral frags i got yesterday, they are not fully bright yet because they may be still adjusting. one is a sun coral the other is xenia and the third is a kenya tree coral.
I have mine quite high up but my lighting isn't that strong (yet!). They are also in quite a high current but not being blasted!! they'll soon let you know when they're not happy!
Xenia, ironically, is a tougher coral to keep. I disrupted my sandbed recently, and have had all sorts of nitrate problems, and my xenia is the only coral that shows any effect.
