St. Thomas Mushroom – Sky Blue or Aqua Blue
St Thomas mushroom (rhodactis sanctithomae) is a soft coral covered in bulb-like or flame-like tips. It is very easy to care for, requiring low to moderate lighting and water flow. It can be placed on the sand and will eventually settle into its natural position. This coral works well with other corals as long as they are kept at a safe distance. St Thomas mushrooms have the ability to sting other corals, so spacing is recommended. While photosynthetic, they can also benefit from zooplankton and brine shrimp for added nutrition.
Typical size: 1″ to 4″

Easy to set up and has grown well in my tank. I placed it on the sand and it settled nicely. I keep it away from other corals to avoid any stinging. It looks beautiful with the sky blue color and adds a nice soft texture to the display.

Grew quickly under moderate lighting. I feed it brine shrimp weekly and it seems to respond well. I made sure to keep it at least 6 inches from other corals to prevent any issues.

The color is vibrant and the coral stays healthy even in a low-flow setup. It’s a great beginner-friendly coral that doesn’t require much maintenance.
