This picture is terrible but this coral is taking over my tank. Been in there about 10 years, started from a dime size frag. You can’t tell but this coral is pink and had tiny polyp extensions throughout the day. Anyone have any ideas?
Edit: This tank is 300 gallons (8ft) and it is covering about 25% of the rock.
