Just sitting here gazing into the tank and a question that I've never
thought of before came to mind.
I'm familiar with coral propagation through what I've read on the web or in
a book. SNIP and glue.
Is it necessary to do OR do corals just simply go on living forever and
regen themselves ?

I can see how polyps spread, but how bout my giant leather ?
The leather I have tripled in size in 6 months.

Thanks,
Chris
