St Thomas Mushroom Green
St Thomas mushroom (rhodactis sanctithomae) is a soft coral covered in bulb 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 preferred location. 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.

Easy to set up and grows well in my tank with moderate lighting. I kept it away from other corals and it hasn’t caused any issues. It looks beautiful with its flame-like tips and stays healthy after a few months.

Grew steadily in my reef tank. I feed it a bit of brine shrimp weekly and it seems to thrive. I made sure to keep it at least 6 inches away from other corals to avoid any stinging.

Very peaceful and hardy. I didn’t have to adjust lighting or flow much. It settled into the sand and started growing within a few weeks. Looks natural and adds a nice texture to the tank.
