Overcrowding and territorial disputes are usually dealt with via chemical warfare (a major stressor), possibly promoting bleaching events, or even rapid tissue necrosis (RTN). Once RTN begins, the affected coral succumbs within a matter of hours (not days as is often believed) and it can quickly spread to other colonies. Immediate action must be taken. More often than not you will end up having to frag the unaffected branches or entire colonies will be lost. A situation best avoided, and a strong argument for providing plenty of breathing room between colonies. Regular carbon use can help to remove this chemical stress before RTN sets in. Another method of territorial domination is growing over (i.e. plating) a coral mounted at a lower level, effectively shielding it from light. The fix for this is simply to frag the offending coral. Allow plenty of room for growth in every direction. For more information read “Toward Success with SPS Corals” by Terry Siegel. " Kan detta vara anledningen till problemen?
