Best Plants for South American Cichlid Tanks
Keeping live plants with South American cichlids can feel like a losing battle. Many of these fish dig, rearrange the substrate, and nibble or uproot anything that gets in their way. The good news is that a planted South American cichlid tank is absolutely achievable; the trick is choosing tough, well-anchored plants and setting them up so your cichlids cannot easily tear them out. Here are the best plants for South American cichlid tanks and how to make them last.
Why South American cichlids are hard on plants
Many South American cichlids, from larger species down to some of the bolder dwarfs, are natural diggers. They sift substrate, excavate pits, and stake out territory — this is most intense around breeding time, and dedicated sand-sifters like Geophagus (eartheaters) are especially tough on loose plantings. Delicate, shallow-rooted plants rarely survive this treatment. That is why the best approach is to lean on hardy species that can be attached to hardscape rather than relying on the substrate, and to accept that a cichlid tank will look more rugged than a manicured aquascape. For more on the fish themselves, see our South American cichlid tank setup guide and compatibility guide.
The toughest, most reliable choices
Anubias
Anubias is arguably the number one plant for cichlid tanks. Its leaves are thick and leathery, so fish tend to leave them alone, and it does not need to be planted in the substrate at all. Instead, you tie or glue its rhizome to driftwood or rock, which keeps diggers from uprooting it. It is slow-growing and undemanding, making it a forgiving choice.
Java fern
Like anubias, java fern attaches to hardscape rather than rooting in the substrate, so it sidesteps the digging problem entirely. Its tough leaves are unappealing to most cichlids, and it tolerates a wide range of conditions. See our java fern care guide for attachment and care tips.
Other hardy options
Sword plants and large crypts can work in cichlid tanks if their roots are well established and protected, since their broad leaves and deep roots make them harder to dislodge once settled. Floating plants are another smart move: they stay completely out of reach of diggers, provide shade and cover that many cichlids appreciate, and help absorb excess nutrients.

How to keep plants anchored
Setup matters as much as plant choice. Attach rhizome plants like anubias and java fern to driftwood or stone so there is nothing to dig up. For substrate-rooted plants, give them time to establish before adding boisterous fish, surround the base with larger rocks to discourage digging, and use a deeper substrate so roots can grip. A good base layer helps too; our aquarium substrate guide covers the options.
Feeding the plants
Heavy root-feeders like swords benefit from nutrients delivered straight to the roots. Root tabs are an easy way to do this without dosing the whole water column; our root tabs guide explains how and when to use them. Regular maintenance keeps everything healthy, and trimming back fast growers prevents a tangled mess; see our guide to trimming aquarium plants.
What about dwarf cichlids?
If you are keeping smaller, less destructive South American dwarfs, you have far more freedom to build a lush planted tank. These fish often thrive in well-planted setups with plenty of cover. Our guide to the best dwarf cichlids for a planted tank is a great place to start if a more aquascaped look is your goal.
