A Pink Lemonade and a Five Hundred Dollar Efflo, as well as a Garf's Bonsai and a Green Acro's bases that are encrusting the rock they're on are about to touch. What will happen when they do? Should I do anything? Will one kill the entire coral? I placed them so that they would not grow into each other but they are encrusting more than I ever thought they would. Any insight would be greatly appreciated.
