7 Beautiful Goldfish Plant Varieties You Can Grow Indoors

If you’ve ever spotted a hanging basket covered in glossy green leaves and little orange blooms shaped like tiny fish, you’ve already met the goldfish plant.

This tropical beauty, Nematanthus gregarius, thrives indoors when you match the right variety to your home’s light and humidity. Some stay compact on a desk, others trail for feet like living ribbons.

I’ve grown several of these over the years, and while all share that playful “fish” charm, each one behaves a little differently. Let’s dive into seven stunning goldfish plant varieties and find the one that suits your space best.

Goldfish Plant (Nematanthus gregarius)

Native to Brazil’s cloud forests, the goldfish plant is a semi-epiphytic species that naturally grows along tree branches where air stays warm and moist but never stagnant.

Indoors, it’s a low-maintenance tropical that rewards bright, indirect light with flowers that look like swimming orange or red fish.

Growth habit: Compact to trailing (12–36 inches).
Bloom time: Mainly spring through fall indoors with enough light.
Ideal temperature: 65–80°F with no cold drafts.
Humidity preference: Moderate (40–60%).

These plants don’t need complicated routines — just steady light, even moisture, and the right-sized pot. But picking the right variety helps you avoid common frustrations like poor flowering or overgrown vines. Here’s where the fun begins.

Goldfish Plant Varieties:

1. Nematanthus gregarius (Classic Goldfish Plant)

If you’re new to goldfish plants, start here. This original species delivers everything people love about them — bright orange blooms, shiny green leaves, and a forgiving nature. It trails gently but doesn’t take over, making it perfect for hanging baskets or a sunny windowsill.

Where it shines: Bright east or north-facing windows, or a few feet from a sunny south window.
Watering: Let the top inch of soil dry before watering again.
Fertilizer: Use a diluted all-purpose liquid fertilizer once a month during active growth.

This variety tolerates small mistakes — missed watering or brief light changes — far better than most tropicals. It’s also easy to revive if you’ve overwatered once or twice.

Expert Tip: Goldfish plants bloom best when slightly root-bound. Don’t rush to repot unless roots circle tightly at the bottom. A snug pot keeps the plant focused on flowering, not leaf growth.

2. ‘Black Gold’ (Nematanthus hybrid)

A showstopper for modern spaces. Its dark, almost black foliage contrasts with vibrant orange flowers that seem to glow. Under the right light, it looks like a living piece of art.

Light: Needs bright, filtered sunlight — east-facing windows or a bright south window with a sheer curtain.
Water: Water when the top ¾ inch feels dry; it dislikes soggy roots.
Humidity: Around 50–55% keeps the dark foliage glossy.

I’ve found this one especially rewarding near a window with steady morning sun. The deep foliage color intensifies when light is strong but indirect.

Expert Tip: Use a pot with excellent side drainage (like a slotted orchid pot inside a decorative sleeve). The improved airflow keeps those thicker roots healthy and prevents fungus gnats.

3. ‘Golden West’ (Variegated Goldfish Plant)

If you prefer something that looks lively even when not in bloom, try ‘Golden West’. Its leaves are streaked with cream and yellow, adding year-round brightness. Orange-red flowers emerge once the plant matures and gets 5–6 hours of light daily.

Light: Slightly higher light than green varieties — an east or bright west window works beautifully.
Soil: Use a loose potting mix (2 parts soil, 1 part orchid bark, 1 part perlite) for extra air circulation.
Feeding: Too much nitrogen dulls the variegation. Stick to a balanced 10-10-10 or 5-10-5 fertilizer.

The color pattern alone makes this a collector’s favorite. It also stays compact and bushy with minimal pruning.

Expert Tip: Rotate the plant every week so all sides get equal light exposure. This keeps the variegation even and prevents it from turning one-sided or leggy.

4. ‘Christmas Holly’ (Nematanthus hybrid)

This variety earns its name for producing red-orange flowers during the holiday season. The foliage is darker than the species, and the blooms stand out brilliantly when the indoor light is cool but bright. It grows upright before arching, so it suits both shelves and baskets.

Light: East or west-facing windows give ideal winter brightness.
Temperature: Prefers cooler nights (60–62°F) to trigger blooms.
Watering: Keep soil evenly moist — drying out can stop buds from opening.

I often use this variety to bring natural color indoors in late fall and winter when most plants are resting. It’s less fussy about humidity than other hybrids.

Expert Tip: To encourage flowering, reduce watering slightly for two weeks in late fall, then resume regular moisture as buds form. The brief “dry rest” mimics its native seasonal rhythm.

5. ‘Freckles’ (Nematanthus hybrid)

If you want personality, this one delivers. ‘Freckles’ has cheerful yellow-orange flowers dotted with red specks. It trails freely, making it perfect for hanging baskets or tall plant stands where its vines can cascade.

Light: Bright, indirect sunlight (6 hours minimum).
Pruning: Trim about one-third of the vines after each bloom cycle to keep them lush.
Watering: Deeply soak, then let the top inch of soil dry before watering again.

It grows faster than most, so pruning keeps it full and balanced. I’ve seen it rebound beautifully even after a strong trim.

Expert Tip: Let the first few trailing vines wrap around the rim of the pot before they hang down. This fills out the top and creates a dense, fountain-like shape.

6. ‘Apres’ (Nematanthus hybrid)

This compact variety is made for small spaces. With its upright, bushy habit and fiery orange-red blooms, ‘Apres’ delivers the same tropical charm without sprawling vines. It grows about 10–12 inches tall and stays neat on shelves, desks, or windowsills.

Light: Thrives in bright but indirect light; a bright kitchen window or grow-light shelf works perfectly.
Water: Keep soil lightly moist—never soggy. Let the top inch dry before rewatering.
Fertilizer: Apply a diluted liquid fertilizer (5-10-5 or 10-10-10) every 3–4 weeks during active growth.
Maintenance: Pinch the growing tips when plants are young to encourage a fuller shape and more blooms.

What I love most about ‘Apres’ is how effortlessly it adapts to indoor living. It doesn’t demand high humidity, and even under standard household conditions, it still flowers generously.

Expert Tip: This hybrid prefers snug pots. Repot only when you see roots creeping out of the drainage holes—crowded roots encourage more flowers.

7. ‘Light Prince’ (Columnea/Nematanthus hybrid)

If you’re after something elegant, ‘Light Prince’ is your pick. Its creamy variegated leaves have soft green streaks, and the reddish-orange blooms add warmth without overwhelming the eye. It’s slower growing than most, but forms a tidy mound that fits smaller homes or humid rooms like kitchens and bathrooms.

Light: Needs strong filtered light—near an east-facing window or under LED grow lights for 10–12 hours.
Humidity: Enjoys slightly higher humidity (50–60%), which you can achieve with a pebble tray or humidifier.
Soil: Use a loose, breathable mix (equal parts peat moss, perlite, and orchid bark).
Fertilizer: Feed monthly at half strength during spring and summer.

Because of its variegation, ‘Light Prince’ doubles as a decorative foliage plant, even when not in bloom.

Expert Tip: If leaf tips brown or turn dull, it’s usually due to salt build-up from fertilizer. Flush the soil monthly with plain water to keep the mix fresh.

How to Pick the Right Goldfish Plant for Your Home

Choosing the perfect goldfish plant depends on three key things: light, space, and maintenance style. Here’s how to decide like a pro:

1. Light levels

Goldfish plants crave brightness but not harsh midday sun.

Bright east or filtered south windows: Go for ‘Black Gold’, ‘Freckles’, or the classic Nematanthus gregarius.
Medium light or north windows: Choose compact types like ‘Apres’ or variegated ‘Golden West’.
Low-light rooms: Use an LED grow light. These plants won’t thrive long-term in dim corners.

Expert Tip: Light equals blooms. If your plant grows healthy leaves but no flowers, increase light by 20–30% before adjusting anything else.

2. Space and growth habit

Ask yourself how much room you truly have.

For hanging baskets: ‘Freckles’ and ‘Black Gold’ trail beautifully.
For shelves or desktops: ‘Apres’, ‘Golden West’, and ‘Light Prince’ stay compact.
For versatile use: The classic species fits both hanging and upright displays.

3. Temperature and humidity

Goldfish plants enjoy consistent warmth (65–80°F). They dislike drafts, air conditioning vents, and sudden temperature swings.

In dry homes, group plants together or use a pebble tray to raise humidity. A small humidifier nearby keeps leaves lush and prevents brown tips.

4. Maintenance preference

Low maintenance: ‘Apres’ and Nematanthus gregarius handle minor neglect.
Moderate care, high payoff: ‘Black Gold’ and ‘Freckles’ bloom heavily if you maintain humidity and light.
Collector’s choice: ‘Light Prince’ and ‘Golden West’ reward consistent attention with striking foliage.

5. Pet safety

If you share your home with pets, good news—goldfish plants are non-toxic to cats and dogs. Still, keep trailing varieties out of reach so curious paws don’t break stems or chew tender leaves.

Care Essentials That Apply to Every Goldfish Plant

No matter which goldfish plant variety you grow—whether it’s the easygoing Nematanthus gregarius or the dark-leaved ‘Black Gold’—they all share the same basic needs indoors. Think of these as the core habits that make the difference between a leafy vine and a steady show of fish-shaped blooms.

Light: Bright, Indirect, and Consistent

Goldfish plants are native to tropical forests where sunlight filters through trees. Indoors, try to replicate that by giving them bright, indirect light.

East or west-facing windows work best; they get strong light without harsh afternoon heat.
South windows can work too, but filter the light with a sheer curtain.
If your home is dim in winter, use a small LED grow light for 10–12 hours daily.

Expert Tip: Rotate your plant once a week. Even light exposure keeps it balanced and prevents one side from stretching toward the window.

Water: Deep Soaks, Then Patience

Overwatering is the biggest mistake new growers make. Goldfish plants like moisture, but they hate sitting in soggy soil.

Wait until the top 1 inch of soil feels dry before watering again.
Water slowly and evenly until it drains out the bottom of the pot.
Always empty the saucer to prevent root rot.
During winter, reduce watering frequency as growth slows.

Expert Tip: Use room-temperature water. Cold water can shock the roots and cause sudden leaf drop.

Humidity and Temperature: Warm and Gentle

Coming from humid Brazilian forests, these plants appreciate moisture in the air—but they don’t demand tropical greenhouse levels.

Ideal humidity: 40–60%.
Ideal temperature: 65–80°F (avoid dips below 60°F).
Keep them away from heating vents, AC units, or drafty windows.
Grouping plants naturally raises humidity around them.

If your home’s air is dry, set the pot on a pebble tray filled with water (without letting the pot sit directly in it) or use a small humidifier nearby.

Soil: Airy, Fast-Draining, and Rich

Because goldfish plants are semi-epiphytic (they grow in tree crevices in nature), they prefer soil that drains quickly but stays lightly moist.
Best mix recipe:

2 parts high-quality indoor potting mix
1 part orchid bark or fine pine bark
1 part perlite or coarse sand

This mix keeps oxygen flowing to the roots while holding just enough moisture between waterings. Avoid heavy peat-only mixes that compact easily.

Expert Tip: If you notice water pooling on the surface instead of soaking in, loosen the top layer gently with a fork to restore airflow.

Feeding: Regular, Light Nutrition

Goldfish plants are modest feeders but reward consistency.

Use a balanced liquid fertilizer (5-10-5 or 10-10-10) diluted to half strength every 3–4 weeks from spring through early fall.
Skip fertilizer in winter when the plant rests.
To encourage more blooms, use a bloom booster with slightly higher phosphorus (the middle number).

Expert Tip: Always water lightly before feeding. Applying fertilizer to dry soil can burn delicate roots.

Pruning and Shaping: The Secret to Fuller Growth

Pruning keeps your plant dense and encourages more flowers.

After each major bloom cycle, snip back the longest stems by 1–2 leaf nodes.
Pinching young shoots early promotes branching and prevents legginess.
Remove any yellow or damaged leaves to improve airflow.

If you want a fuller look in a hanging basket, train a few vines back over the rim before they trail down—this fills out the top beautifully.

Expert Tip: Never cut more than one-third of the plant at a time. Frequent light trimming is far better than one heavy prune.

Repotting: Less Often Is Better

Goldfish plants bloom best when their roots are comfortably snug.

Repot only every 2–3 years, or when you see roots escaping the drainage holes.
Move up just one pot size (1 inch wider).
Always refresh the potting mix during repotting to restore nutrients.

Expert Tip: A snug pot keeps energy focused on flowering rather than leaf growth. Oversized pots hold excess moisture that can drown roots.

Sticky residue on leaves	Natural nectar secretion	Move closer to the bright window; resume monthly feeding
Pale, thin growth	Not enough light or nutrients	Leaf tips are turning brown

Seasonal Adjustments

Goldfish plants follow a mild seasonal rhythm even indoors:

Spring–Fall: Active growth and bloom season. Keep humidity moderate, feed monthly, and trim lightly.
Winter: Slower growth. Water sparingly, stop fertilizing, and give maximum available light.

By respecting this natural rhythm, your plant resets and returns stronger each spring.

Expert Tip: Keep a small notebook or app log. Jot down dates of watering, feeding, and blooming cycles. Goldfish plants thrive on consistency—and tracking helps you spot small patterns before they become big issues.
