What the sources say about its care

The sources disagree about light for this plant. Both readings are shown in the table below. This is the norm in houseplant advice rather than the exception.

Light

The sources disagree. These do not describe the same conditions: Clemson Extension says "Medium light" and RHS says "Full sun". Both are shown; this site does not pick between them.

About the plant

Caryota mitis, known as the clustering fishtail palm or fishtail palm, is a species of palm native to Tropical Asia from India to Java to southern China, now sparingly naturalized in southern Florida and in parts of Africa and Latin America. The species was originally described from Vietnam in 1790. In Florida, it grows in hummocks and in disturbed wooded areas.

Uses

What sources record people using this plant for. A traditional or medicinal use listed here is a record of use, not advice to eat it or treat anything with it.

Fishtail palm serves as a poison, a medicine, fuel and food. Its immature seeds can be eaten (they are sold canned as a delicacy), but the berries are toxic.

What this does not cover

The figures above are what published sources say, not measurements of the plant in your room. They say nothing about your pot size, your water, the season, or how far from the glass the plant stands, and those decide more than any figure here does.

Humidity has no species figure because no source read for this site publishes one, and the only temperature published for this plant is a cold floor. The simulator fills those gaps with general figures for its kind of plant, marked as general and listed on how we read sources. Where a toxicity row says the plant was not assessed, that is the absence of a finding and not a finding of safety.

If something is already wrong, the diagnosis tool asks about the soil, the window and the watering, which is where the answer usually is.
