Live or Artificial Plants: What Should You Choose to Decorate Your Aquarium?
A bare aquarium stresses its inhabitants: fish need hiding places, shaded areas and landmarks to establish their territories. So the question isn't whether to plant, but what to plant with. Live plants or artificial? At Planète Pets, we've weighed the pros and cons.
Live plants: far more than decoration
Real plants work for you: they consume nitrates, produce oxygen during the day, compete with algae and provide spawning sites. A well-planted tank is more stable and healthier. Budget-wise, allow 3 to 8 € per pot or stem, i.e. 30 to 60 € to plant a 100-litre tank properly. The constraints: suitable LED lighting, regular trimming and, for hungrier species, a nutrient-rich substrate.
Five nearly foolproof plants for beginners
- Anubias: slow-growing, attaches to wood or rock, withstands even goldfish.
- Java fern: likewise, and tolerates low light.
- Vallisneria: fast-growing, perfect as a background plant, a big nitrate consumer.
- Cryptocoryne: discreet and robust once established.
- Java moss: a favourite refuge for fry and shrimp.
Artificial plants: when do they make sense?
Plastic or silk plants (2 to 15 € apiece) require no maintenance or special lighting, and some imitations have become remarkably convincing. They earn their place with fish that uproot or devour everything, or in a hospital tank that gets disinfected regularly. Their limits: no biological role whatsoever, and a risk of injury with rigid models that have sharp edges. Choose soft fabric versions, especially for a betta with its long, delicate fins.
Think enrichment, not just aesthetics
Whatever you choose, give the tank structure: mangrove or spider wood roots (10 to 40 €), inert rocks, ceramic caves, densely planted zones at the back and open swimming space at the front. A complex environment reduces stress, curbs aggressive behaviour and makes your fish visibly more active. The decor rests on a good substrate, to be chosen before filling the tank.
Our verdict
If your setup allows it, live plants win hands down: they contribute to the tank's balance while decorating it. Artificial plants remain a respectable backup solution in specific cases. Discover our selections of decor and plants in the tank enrichment section and all our guides on the fish hub.
