Mushroom Corals: A Hobby Name With Important Limits
The mushroom corals sold under names such as Discosoma and Rhodactis are corallimorpharians. They are related cnidarians rather than simply small versions of skeleton-building stony corals.
Start with the name
A trade label, color or patterned oral disc does not guarantee a genus or species identification. Keep supplier records and look at the whole animal and its attachment area in a clear image. Do not cut, detach or provoke it to obtain a diagnostic view.
Watch the surrounding space
An expanding disc can occupy more room than its initial attached base suggests. Note contact with nearby animals and the movement of loose or detached material. Similar common names do not supply a universal compatibility rule.
Keep care observations grounded
- Record previous and current position and lighting.
- Use consistent photographs of size and tissue appearance.
- Include recent changes and measured conditions when seeking help.
- Avoid declaring an animal hardy enough to tolerate unsuitable conditions.
About the artwork
The illustration is a simplified corallimorph-like disc and is not a verified photograph of Discosoma or Rhodactis. Its purpose is to explain what to observe, not to establish the identity of your animal. Use a taxonomic reference and source history for that discussion.
