Updated: April 8, 2022

Cardinalis aquarium plants are beautiful and popular among aquarium enthusiasts. However, one common problem that many aquarium owners face is the presence of fruit flies on their Cardinalis plants. These tiny insects can be a nuisance, and if left unchecked, they can cause damage to the plant. In this article, we will discuss how to get rid of fruit flies on Cardinalis aquarium plants.

Identify the Problem

The first step in getting rid of fruit flies on Cardinalis aquarium plants is to identify the problem. Fruit flies are small insects that are attracted to decaying organic matter. They lay their eggs on the surface of the soil or in decaying plant matter, and their larvae feed on the organic matter. If you notice tiny flies hovering around your Cardinalis plant or crawling on its leaves, it’s likely that you have a fruit fly infestation.

Remove Decaying Organic Matter

The next step in getting rid of fruit flies on Cardinalis aquarium plants is to remove any decaying organic matter from the aquarium. This includes dead plant matter, uneaten fish food, and any other debris that may be present. Use a net or a siphon to remove any debris from the substrate or the water column.

Clean the Aquarium

Once you have removed all decaying organic matter from the aquarium, it’s time to clean it thoroughly. Use an aquarium-safe cleaner to clean the glass walls and any decorations in the tank. Rinse everything thoroughly with clean water before putting it back into the aquarium.

Use Sticky Traps

Sticky traps are an effective way to catch fruit flies in your aquarium. You can purchase pre-made sticky traps or make your own by placing a piece of yellow sticky paper near your Cardinalis plant. The bright color of the paper will attract the fruit flies, and they will become stuck on the paper.

Introduce Beneficial Insects

Another way to get rid of fruit flies on Cardinalis aquarium plants is to introduce beneficial insects into the aquarium. There are several species of insects that feed on fruit flies, including ladybugs, lacewings, and parasitic wasps. You can purchase these insects from a pet store or online.


In conclusion, getting rid of fruit flies on Cardinalis aquarium plants requires a combination of cleaning, removal of decaying organic matter, and introducing beneficial insects or using sticky traps. By following these steps, you can keep your Cardinalis plant healthy and free from fruit fly infestations.
