Note any red or yellow spots on the coral. Red water bugs are often easy to see on the shaded underside of a coral branch.
Examine any spots you see. Acropora red bugs are small crustaceans that look like mites or very small shrimp. They are about half a millimeter in length and are yellow with a red dot.
