Micromussa question

[Mr.First]

When you get a small frag with broken heads, do they grow back full. Also do they spread ? If so, do you do like with Zoo's putting the frag right up against a bear rock. Are they difficult to keep ?
Flow ?
Light ?

Thx.

sometimes the broken heads will grwo back. sometimes they'll just die off.

They're an LPS so they build their own skeleton. The colony will grow by itself. No need to put another rock next to it.
