Zoa's under a 6500K bulb?
 

I was wondering if any zoas would grow under a daylight (6500k) cfl bulb. i know the colors would not be so great. but was interested if they would still grow at all.

I have a small 5.5 gallon tank that is sitting and wanted to see if i could use it a low tech zoa grow/frag tank.

All coral will grow under 6500k.....very well in fact.....downside to 6500k is that it is near the spectrum of natural sunlight so it will also grow lots of algae and the color of the bulb is yellow

You could always supplement with a clip on CFL fixture for actinic (which is mainly for color anyhow).

I set up a 3gal nano with a 6700K bulb and it grow zoanthids, GSP< Xenia, I even put a blasto that wasnt doing well in my tank in there and its starting to come back.
