Coral nurseries are Farming patches used to cultivate coral, which are useful as ingredients for making potions. After completion of Troubled Tortugans, players can access the two nurseries in the Coral Nurseries, a location beneath the eastern coast of The Great Conch. Players need to wear either a diving apparatus and a fishbowl helmet, or a Medallion of the deep to access the area.

One frag can be placed on each nursery to start growing coral. Unlike most farming patches, coral nurseries cannot be treated with compost to reduce disease risk or to increase yield. However, the nearby gardener Chet can be paid to protect both patches from disease, which is highly recommended.

Similarly to herb patches, players may increase harvesting speed over the automatic rate by starting to harvest, waiting 2 game ticks, then clicking again. This will harvest 2 coral per animation, effectively doubling harvest rate for the nursery. The increased speed can also be achieved without any need for precise timing by spam-clicking during the first two ticks of harvesting.

Obtaining coral frags

• Elkhorn frags can be obtained from looting the rusty chest ( 33 ) on Dognose Island ( 40 ) or Vatrachos Island ( 46 ) and rarely from sorting large salvage.
• Pillar frags can be obtained from looting the tarnished chest ( 54 ) on Shimmering Atoll ( 49 ) or The Crown Jewel ( 64 ) and very rarely from sorting large salvage.
• Umbral frags can be obtained from looting the reinforced chest ( 76 ) on Ynysdail ( 73 ) or Brittle Isle ( 81 ) and rarely from sorting martial salvage.

All three frags are also relatively common drops from aquanites (requires 78 and 73 ).

Changes

Date	Changes
17 December 2025 (Update)	The chance of all coral variants getting diseased was reduced. The harvest yield of all coral variants was increased. The minimum yield is now 4 at all Farming levels, increasing as the player's Farming level increases, with a decent chance of receiving over 16 at level 99.

Trivia

• In reality, a coral nursery is an artificial structure to form the base of a reef when propagating coral from frags. They allow for better chances at survival, and control over what species grow. They are often used with the intention of transplanting the coral elsewhere.
• Unlike most "crops" that can be grown with the farming skill, coral are not plants, but rather colonies of identical small invertebrate animals called 'polyps', which along with many other species come together to form an ecosystem called a coral reef.
  • They share the distinction of not being a plant with mushrooms and seaweed.
• Although the player only uses one frag on a nursery to grow coral, four of the respective frag appear on the nursery when placed.
