Watermelon Zoanthid
This zoanthid is easy to keep and is a great choice for beginners. Zoanthids and Palythoa grow and reproduce by budding. The polyp has the ability to sting other polyps or corals. While the sting is not strong, sufficient space should be provided between the colony and other corals due to its semi-aggressive temperament and potential to crowd out neighbors.
Some zoanthids and Palythoa contain a powerful neurotoxin called palytoxin in their flesh. Palytoxin can be extremely harmful and even deadly if it comes into contact with the bloodstream. Take special care when handling these polyps, especially if you have open cuts on your hands.

Easy to set up and grows well in my 20-gallon tank. I kept them spaced out from other corals and haven’t had any issues. Just make sure to wear gloves when handling them.
Stewart Nolan –
Grew quickly and added a nice color to the tank. I noticed they occasionally stung nearby polyps, so I increased spacing. Still worth the effort.

The color is vibrant, but I had to be careful when handling. I now use gloves and keep them away from my hands. Good for experienced hobbyists.
