Aquarium Plants for Toothless Catfish

To mimic their natural habitat, we recommend adding live aquatic plants to your aquarium. Toothless catfish are a large species and can disrupt plants easily, however they require lots of driftwood in the aquarium for shelter, so we suggest using anubias planted on driftwood. Anubias is a hardy plant with a firm leaf that will tolerate moderate disruption and lower lighting. When planted on driftwood, the plant has no way of being uprooted. It's rooted to the driftwood already, and ready to go.
