I've been interested in reef aquariums for years. However, something I find perplexing is that many of coral species cannot be close to one another since they are toxic to each other. Well, some of the beautiful tank I see pictures off look like they are almost stacked up one another. So, What gives? Can you let them touch or is it stricktly s soft/hard coral issue.
