The fishbone cactus (Disocactus anguliger) originating in Mexico, is distinctively shaped. With a stem and leaf pattern similar to the skeleton of a fish, it’s no surprise this is a common moniker.
Another popular name for this plant is the zig zag cactus.
This plant is an epiphyte
and as such, you’ll notice it also has aerial roots.
For beginner plant owners, a fishbone cactus is an ideal option. Bright, indirect light and a humid environment are a few requirements for this plant to flourish.
Furthermore, this plant makes a great conversation piece. Who wouldn’t ask about it when seeing its unique pattern flowing out of a hanging basket or trailing down a table or plant stand?

Basic Care Tips
Light Requirements
As previously noted, your fishbone cactus requires bright, indirect light in order to thrive. Ideally, you’ll want to place your plant in a location that gets about 6 hours of bright, indirect light, daily.
Avoid an area that gets direct sunlight, as this will ultimately harm your plant.
Watering Needs
The fishbone plant’s watering needs differ from other cacti in that it needs to be watered more often, approximately every 7 to 10 days.
Water your plant when the top portion of the soil is dry. Test this by putting half of your forefinger in the potting soil. If your finger is clean when you take it out and the soil feels dry, you need to water your plant.
Be sure to pour the water out of the drainage tray so that your plant is not sitting in water.
Additionally, water your plant with lukewarm water, as cold water will negatively affect the roots.
If possible, use filtered water, given that fishbone cacti are sensitive to the minerals in tap water. If you don’t have filtered water, pour tap water into your watering can and leave it on a shelf for at least 24 hours before watering your plant.
Soil Requirements
Your fishbone cactus needs potting soil that drains well.
Ideally, a standard cactus mix, with peat moss and perlite added to it, will improve the drainage.
Temperature and Humidity
An environment that is warm and humid is best for this plant.
So, a temperature range between 61°F and 77 °F (16°C and 25°C) is good, as well as humidity levels above 55%.
Placing your plant on a tray of pebbles is one way to keep the humidity level high. All you need to do is fill a tray with pebbles and add water, making sure that the water level isn’t higher than the top of the pebbles. Then put your plant on top of the tray. The moisture around the plant will increase as the water evaporates due to increased humidity.
Additionally, a plant humidifier will emit a light mist over your plant, providing the right amount of humidity.
If the temperature drops below 50°F (10°C), this could negatively affect your plant.
Fertilizing Needs
Fertilize your fishbone cactus once during the growing season (spring and summer months). A liquid fertilizer specially for cacti or succulents, is preferred.
Pruning Needs
This plant doesn’t need to be pruned on a regular basis in order to thrive.
It grows at a medium pace and the stem cuttings that are pruned can be propagated so that you can have more plants.
Propagating
As previously outlined, your fishbone cactus can be propagated by stem cuttings.
Follow these steps:
- Remove one or more 4 to 6-inch (10 to 15 cm) stem cuttings using pruning shears.
- Put the cuttings aside for 1 to 2 days to provide the cut ends with time to dry up.
- Plant the dry ends into a pot containing well-draining, dampened potting soil.
- Keep the soil moist by watering the cuttings a few days per week.
- Roots will develop in a few weeks, and you can repot the cuttings in separate containers.
Repotting Needs
Repot your fishbone cactus every couple of years in a container slightly bigger than the one it’s currently in. The container must have drainage holes and as previously outlined, potting soil that is well-draining is best for this plant.
Common Issues
Wilted and discolored appearance
If the foliage and stems of your fishbone cactus look wilted and pale, this is the likely result of underwatering. In this case, once you increase the watering frequency, you’ll revive your plant.
Root rot
On the other hand, overwatering or insufficient drainage will result in root rot. Soft, mushy stems and roots are a few indications of root rot. For more information on handling this, here are some tips for root rot.
Sunburn
Too much sun exposure will burn the foliage, which will appear slightly red or brown in color. To combat this, move your plant to a spot that gets bright, indirect light.
Pests
Look out for mealybugs, scale, spider mites and fungus gnats, as these common pests can affect your fishbone cactus. Treating your plant with neem oil or insecticidal soap are a few ways to get rid of them. Here are some tips on dealing with these pests.
Questions
How big does the fishbone cactus get indoors?
The plant’s stems can trail about 2 to 3 feet long (61 to 91 cm) indoors
How long will the fishbone cactus live?
With the right care, this plant has been known to live for at least 10 years indoors.
Conclusion
Overall, the fishbone cactus is a beautiful and unique plant that makes a great addition to any indoor space.
So, if you’re looking for an attention-grabbing plant to decorate your home with, the fishbone cactus is for you! It’s easy to care for and thrives in bright, indirect light and an environment with high humidity.
