Fancy goldfish can be particularly voracious eaters, so some keepers of these aquatic beauties may opt to use only fake or artificial plants that won’t be damaged. But there are still options available to those keeping goldfish that will add beauty and extra nutrition to the tank.
Hornwort (Bacopa monnieri) is an ideal option that grows quickly and can be tough for goldfish to nibble at, while also helping absorb any excess nitrates in the water.

Hornwort
Hornwort (Ceratophyllum demersum) is an attractive fast-growing plant that adds color and texture to aquariums. It can tolerate a range of conditions including temperatures and nutrient levels. Furthermore, hornwort oxygenates the water as it releases chemicals that kill competing plants (called allelopathy).
Hornwort thallus typically features lobed or wrinkled forms with strap-like and branching structures; in certain species this thallus may even become strap-like. Composed of many cells with chlorophyll in them, its cells often possessing an overall yellow or whitish hue due to chlorophyll content; it may turn green if colonies of Nostoc (cyanobacteria) exist in its cells.
Hornwort can spread rapidly and become an issue in certain tanks when it blocks light or forms thick mats, blocking out light sources or creating thick covers of coverage. For optimal growth conditions it should be combined with floating plants suited for low lighting environments like Java moss, American waterweed or Sagittaria.
Elodea
Hornwort can deter goldfish, making it one of the best aquarium plants for tanks with goldfish.
Elodea (commonly known as oxygen weed) is another great aquarium plant that won’t get devoured by goldfish, providing additional green matter and helping control algae in any tank.
Java fern is another excellent choice, making an eye-catching background or midground plant and being resistant to goldfish attacks. While it does require special care, maintaining healthy and happy aquarium conditions should not be too challenging. Propagation is straightforward using stem cuttings; furthermore it tolerates various lighting levels without needing substrate.
Java Moss
There is much debate regarding java moss and goldfish. Some individuals claim that goldfish nibble on it while others insist they do not, ultimately it comes down to each individual fish and what type of diet it has been fed on by its tankmates. Since it is such a resilient plant it should withstand most nibbling attempts in an aquarium setting.
As part of any aquarium environment, oculina makes for a stunning sight – it looks stunning draped around driftwood or branches! Easy care requirements allow it to flourish even under low lighting conditions.
Water plants are excellent at filtering nitrates out of the tank water and harboring beneficial bacteria, helping maintain an aquarium that’s both clean and balanced, as well as providing goldfish with nutritious snacks! Adding one into the aquarium tank can keep its ecosystem healthy while giving goldfish some healthy snacks!
Water Lettuce
Water lettuce (Pistia stratiotes) is an aggressively growing floating plant that forms dense mats on the water’s surface, cutting oxygen levels and blocking sunlight for other aquatic life, creating an unwanted invasion in natural bodies of water.
But, they make for great options in goldfish tanks as it makes chewing difficult for the fish and allows them to hide within its long roots. Furthermore, the long roots provide shade as well as providing space for reproducing fry (baby fish).
Like Java moss, this plant does not do well with adult goldfish but makes an attractive addition to any aquarium when placed near juveniles. As with java moss, this one prefers being secured to something solid such as bogwood or terracotta sticks rather than free in the water itself.
Duckweed
Duckweed is a quick-growing aquatic freshwater plant that goldfish love to nibble on for nutrition. If left unmanaged, however, it can overpopulate the tank and be harmful to them.
As with any plant, duckweed must be used with caution and from a reliable, pesticide-free source. Also make sure your goldfish have plenty of other sources for food so they do not become dependent on it alone. Furthermore, make sure the lighting in the aquarium remains low to prevent the duckweed from taking over your tank and becoming harmful to its inhabitants’ health.
