Back in February I purchased an unknown acropora from a local store at our frag swap. I thought it was interesting, that it had potential. I had no clue what it was, but something grabbed my interest so I bought it. Looking back at it today, I don't know what I was thinking. lol

Under white lighting:

As you can see, there were hints of blue.  Here it is again under 20,000K lighting.

Lots of corals look better in blue lighting but that can be misleading. White light lets me study corals, especially their health. I'd urge you to look at your reef under whiter conditions often, as this will allow you to correct any issues before they spiral out of control.  

And here's the coral today... it's doing great!

Maybe one day I'll know what it is, and can stop calling it The Unknown Acro. ;)
