Salvinia Minima - Easy Plants for Fish Tanks | Scallywag's Fish Bowl

Salvinia Minima is a free-floating fern known for its fuzzy, oval-shaped leaves and trailing root structures that dangle below the surface. It multiplies rapidly in nutrient-rich water and helps reduce nitrate levels while blocking excess light to discourage algae growth. This plant does best with moderate surface movement and plenty of light but can thrive in a variety of freshwater conditions.

Salvinia Minima is popular in aquariums as a natural surface cover. It provides shade, reduces algae by limiting light penetration, and offers excellent hiding places for fry and shrimp. Its soft texture and floating nature make it ideal for sensitive species that appreciate gentle cover.

Many aquarists also use Salvinia Minima to assist in nutrient control and to create more natural-looking biotopes. It’s a great option for breeding setups, shrimp tanks, and community aquariums alike—especially when you're looking for a floating plant that won’t root or take over the substrate.
