Hairy Mushroom (Rhodactis Indosinensis)

The Hairy Mushroom is a corallimorph whose disc-shaped body is covered in short, hair-like tentacles, giving it a distinctively fuzzy texture. Colors vary between individuals, ranging from brown and purple to tan and green. It doesn't build a skeleton, and under good conditions it readily reproduces by splitting, gradually spreading to carpet the rockwork it settles on. Considered beginner-friendly, it rewards patience as a colony slowly fills in over time.

About Hairy Mushroom (Rhodactis Indosinensis)

A corallimorph known for its hair-like tentacles. Beginner-friendly and spreads over rockwork through splitting.

7 things to know before welcoming a Hairy Mushroom (Rhodactis Indosinensis)

  1. 1No Skeleton, Soft Body

    The Hairy Mushroom is a corallimorph that does not build a calcium skeleton. Unlike hard corals, its body is soft, and it attaches firmly to rock with its pedal disc.

  2. 2Fuzzy Tentacle Texture

    Its most distinctive trait is the surface of the disc, entirely covered in short, hair-like tentacles. This gives it a fuzzy, soft-looking texture quite different from other mushroom corals.

  3. 3Wide Range of Colors

    Colors vary widely between individuals, including brown, purple, tan, and green, making color selection part of the fun. Multiple color morphs can be combined in a single tank as they form a colony.

  4. 4Spreads Gradually by Splitting

    Under suitable conditions, individuals split to multiply, gradually spreading to cover the rock surface over time. As the colony grows, portions can be fragged and relocated elsewhere in the tank.

  5. 5Beginner-Friendly Care

    This species is rated beginner-friendly, making it approachable for those just starting out with coral keeping. That said, basic water quality management and adequate lighting are still required.

  6. 6Placement and Spacing

    Because it spreads through splitting, it's important to leave enough space between it and other corals when placing it. Planning your rockwork layout with future growth in mind helps avoid overcrowding.

  7. 7Check Your Tank Environment First

    Before bringing one home, check compatibility with existing corals and confirm there's enough space in your layout. A stable tank environment also helps it settle in calmly.
