What is a Kenya tree coral?
Kenya trees form thick trunks with branches that look like small trees, with polyps clustered toward the branch tips.[1] They come from the Indo-Pacific, from the African coast to the western Pacific, including the Red Sea.[1, 4] They reproduce asexually: a swelling forms at the base of a branch, which drops off and roots on a new surface.[1]
The trade name usually refers to the genus Capnella, sold as Capnella sp. and now placed in the family Capnellidae (older sources say Nephtheidae).[6, 1] Reef Builders argues that the common brown, weedy 'Kenya tree' is actually a Litophyton and that Capnella is usually minty green, so a coral sold under this name may be either.[2]
Lighting for a Kenya tree coral
Retailer Frag Box says it does well under almost any lighting and adapts to high or low light.[5] We found no reliable PAR figure.
Flow and placement
Moderate. Quality Marine says moderate to strong; Frag Box says low to medium, avoiding strong direct current.[3, 5] In the wild it grows on deeper reef slopes with clear water and stronger currents.[4]
Feeding
Wikipedia and Quality Marine describe it as mainly photosynthetic, also catching small particles, while the Cleveland Metroparks Zoo profile says it relies more on food in the water. Frag Box says it has no special feeding needs.[1, 3, 4, 5]
Aggression and spacing
Its weapons are chemical, not stinging. Quality Marine says Capnella release toxins when stressed that can harm nearby corals, and the Cleveland Metroparks Zoo profile says it deters neighbours chemically, most noticeably as a large colony.[3, 4] Frag Box finds it peaceful next to soft corals but harmful to stony corals on contact.[5] Its other habit is spreading: Reef Builders calls the common strain almost invasive.[2]
Tankmates
Keep it away from stony corals.[4, 3, 5] We found no reliable source naming fish or invertebrates that eat it.
Fragging and propagation
It frags itself by dropping branches.[1] To do it by hand, cut a branch with scissors or pinch it off.[5] We found no reliable source on the best way to attach cut pieces.

Kenya tree coral FAQ
- Is Kenya tree coral toxic?
- To other corals, potentially: it releases chemicals, especially when stressed, that can harm nearby corals.[3, 4] We found no source reporting a hazard to people.
- Why is my Kenya tree coral dropping branches?
- That's how it reproduces: swellings at the base of a branch pinch off and root elsewhere.[1]
- How fast does Kenya tree coral grow?
- Fast. Frag Box rates its growth as extremely fast, and Reef Builders calls the common strain almost invasive.[5, 2]
- What is the scientific name of Kenya tree coral?
- Usually Capnella sp., now in the family Capnellidae;[6, 1] Reef Builders argues the common brown Kenya tree is really a Litophyton.[2]
