Fairly easy to maintain and exhibits little aggression to neighboring corals. The most common form is bowl or goblet-shaped varieties, however, some form scroll or flat plate-like forms and occasionally encrust rocks, columns, or even branches. Environmental factors such as light and water currents are the two conditions that most impact its adapting/forms. Bowl shaped specimens usually come from deeper water where the coral is attempting to gather as much light as possible with its bowl-like shape. Scroll-shaped specimens usually come from shallow water and may be more colorful, such as the yellow T. mesenterina and T. reniformis species, which have polyps usually less than 1 mm high. When irritated, these corals can dispense copious amounts of clear mucus. If this mucus touches other corals it can damage them as it is presumed to contain nematocysts or a toxin used as a defense mechanism.
