How to care for Goldfish Plant

Nematanthus gregarius · Gesneriaceae

floweringmoderate to growpet-safe

The goldfish plant's small, puffy orange blooms really do look like a school of goldfish swimming among glossy, dark, succulent-like leaves. It trails politely, blooms for long stretches, and tolerates average home conditions better than most flowering gesneriads. Consistency is its love language — it drops leaves when conditions swing. Water roughly every 6 days while it's growing (about every 10 in winter), give it bright, indirect light, kept above 59°F (15°C) — average room humidity suits it.

Care at a glance

Water: every ~6d growing · ~10d dormant
Light: Bright, indirect light
Humidity: average room humidity
Keep above: 59°F (15°C)
Feed: every ~14d in season
Repot: every ~2 years

Water when the top few centimeters dry — its slightly succulent leaves buy tolerance for brief dryness but not for soggy soil.

Bright, indirect light, such as near an east window; good light is what turns a green trailing plant into a blooming one.

Quarter-strength high-phosphorus feed every 2 weeks during spring and summer.

Mistakes that kill this plant

  • Cold drafts and temperature swings, which defoliate it.
  • Waterlogged soil in a heavy mix.
  • Keeping it in dim light and expecting fish — it needs brightness to bloom.

Seasonal tips

  • Slightly cooler, drier conditions in winter followed by spring warmth encourage heavy budding.
  • Pinch stem tips after flowering to keep it bushy — blooms come on newer growth.
  • Avoid moving it around while budded; sudden changes make buds abort.
