So I finally decided to jump into the coral aspect of the reef tank. Tank has only been up for about 3 months, and I wanted to take it slow. So I jumped on two very small beginner coral that were on sale, got them both for about $14.00. Grabbed a Duncan and a GSP. Put them in yesterday evening and twelve hours later they have both opened up and look like they are enjoying themselves. Eventually, I will move the GSP and isolate it to a small rock in the open. Anything I should know tips/tricks with the Duncan?

The duncan will appreciate low light and low to moderate flow. They duplicate pretty quickly, when I started the hobby over 3 years ago, I had a single head much like yours, today I have so many I can't even count the total, its easily the size of a softball
