Coral Growth Rates

A friend at work was asking about coral reproduction in my saltwater fish tank so I thought I'd slap together a few images of "before and after" to show how fast corals grow and what they look like when they get bigger or spread out. I apologize for the poor picture quality in a few instances; some images had to be cropped out of larger ones.

1. All my corals are under 36" 96 watt bulbs
2. 92 total watts in a 65gallon tank
3. 1x 10,000 kelvin bulb
4. 1x Actinic 03 blue bulb

The first example is my orange birdsnest coral (Seriatopora hystrix).

This is my large colony of orange zooanthids (Zoanthus sp.). As you can see, the colony has probably more than tripled in 7 months. Right now, they are completely covering the original rock and have started spreading to the rocks around them.
