Elegance touching each other?

[ReeferWade]

Can elegance be right up next to each other or do they need ample room between them? 

[jservedio]

They can be right up against each other. In general, corals of the same species can be touching and won't fight each other. Corals of the same genus can typically get closer to each other before fighting and sometimes never fight, even after touching.

 

For example, pretty much everything in the micromussa  genus can be pretty aggressive. However, Micromussa Lordhowensis (Acan Lords) and Micromussa Amakusensis (Micros) will grow right into each other and never attack each other.

 

Again, this is just "usually" the case and there are always outliers.
