Baby Rubber Plant

Peperomia obtusifolia

Also known as Peperomia obtusifolia, Pepper Face, American Rubber Plant

Plantae›Piperaceae

Thick, glossy spoon-shaped leaves on a tidy, pet-safe little plant. Grown emersed with its roots in the tank water, it works as a living biofilter — pulling up nitrate while the foliage stays in the air.

Terrestrial / emersed plant

Grown with its roots in the tank water and its leaves in the air: a living nitrate filter, not a submerged aquarium plant. Give it bright indirect light; no aquarium CO₂ or substrate needed.
