About Green Hairy Mushroom
Hairy mushroom corallimorph in fluorescent greens — almost indestructible and tolerant of low light. A common nano-reef centerpiece and one of the cheapest ways to add a splash of color. Spreads gradually but not invasively.
Notes from the editors
What it looks like. Hairy mushroom corallimorph in fluorescent green or yellow-green, with short tentacles giving the surface a textured "hairy" appearance. Distinct from smooth Discosoma mushrooms.
In your tank. Nearly indestructible and tolerant of low light, fluctuating parameters, and high-nutrient systems. Reproduces slowly by pedal laceration. Reef-safe to other corals.
Placement and care. Low light, low flow. A common pick for new nano reefs since it tolerates the early instability period most other corals don't. Place on low rockwork or the sandbed.
Sourcing and feeding. Captive-propagated specimens widely available and inexpensive ($10–20). Photosynthetic with no target feeding required, though occasional feeding of small meaty pieces is appreciated.
Care info is a starting point, not a guarantee. Individual specimens, water chemistry, and tankmate dynamics vary. Verify against multiple sources and adjust to what you observe. See our terms & disclaimers.
