Care Guides

Practical, step-by-step guides to keeping zoanthids and palythoa healthy. Start with the topic you need:

  • Lighting: Zoanthids do best under moderate, steady light, and new frags should always start lower and work their way up.
  • Water Flow: Moderate, indirect flow keeps zoanthids clean and open without pinning their polyps shut.
  • Water Parameters: Zoanthids tolerate a wide range of conditions, but stable salinity, temperature, and alkalinity matter more than chasing perfect numbers.
  • Feeding: Zoanthids get most of their energy from light, but light feeding can speed growth and help colonies recover.
  • Fragging: Fragging zoanthids is simple, but it should always be done underwater with gloves and eye protection.
  • Pests: Most zoanthid pests come in on new frags, so quarantine and careful inspection prevent most problems.
  • Dipping: A coral dip knocks off pests before they reach your display, but it only works if you repeat it and inspect carefully.
  • Palytoxin Safety: Palytoxin is a serious hazard, but simple precautions greatly reduce the risk when keeping zoanthids and palythoa.
