The most visible polyps are the gastrozooids (responsible for feeding), the gonozooids (reproductive), and the tentacles, which are specialized and highly retractile polyps.
We established each pairing by excising a small piece of tissue carrying three to four gastrozooids from the sexually immature stock colonies of each contestant in a pairing, and then positioning these explants under monofilament threads approximately 5 mm apart on glass slides.
