Bacopa Australis
Bacopa australis
A compact, small-leaved Bacopa from southern Brazil, producing round to oval light-green leaves on reddish stems. Grows slower and stays shorter than B. caroliniana, making it better suited to midground placement or smaller tanks. Under high light, the stems take on a reddish-orange tint that adds warmth to the scape. One of the most beginner-friendly stem plants available — it rarely melts and grows reliably even without CO₂.
Bacopa Caroliniana
Bacopa caroliniana
Bacopa caroliniana is a robust, easy-going stem plant with rounded, fleshy leaves arranged in whorls along upright stems. Under high light the leaves develop a golden to pale-pink tinge; under low light they remain mid-green. It has a distinctive lemon scent when leaves are crushed. A reliable background or mid-background plant for community tanks and an excellent beginner stem plant that tolerates a wide range of conditions.
Bacopa Colorata
Bacopa sp. 'Colorata'
Pink-tinged Bacopa that offers more colour than standard green varieties. Rounded leaves with a warm glow under good light.
Bacopa Compact
Bacopa caroliniana 'Compact'
Shorter, denser form of Lemon Bacopa. Tight leaf spacing creates a bushy look without frequent trimming. Very low maintenance.
Bacopa Japan
Bacopa sp. 'Japan'
Fine-leaved Japanese Bacopa with small, paired leaves. Grows more delicately than common Bacopa. Nice midground texture.
Bacopa Monnieri
Bacopa monnieri
A classic beginner stem plant with thick, succulent-looking round leaves arranged in opposite pairs along stiff stems. Growth is slow to moderate, making it easy to maintain shape. It adapts to a wide range of conditions and does not need CO2 to thrive, making it one of the most versatile aquatic plants available.
Bacopa Salzmannii
Bacopa salzmannii
A larger-leaved Bacopa with attractive, broadly oval leaves. Under high light, the foliage develops a beautiful pinkish-purple coloration that makes it a standout mid-ground or background accent. More colourful than B. monnieri and responds well to fertilisation.
Bala Shark
Balantiocheilos melanopterus
Balloon Molly
Poecilia sphenops
Balloon Ram
Mikrogeophagus ramirezi
Bamboo Shrimp
Atyopsis moluccensis
Banana Plant
Nymphoides aquatica
The banana plant is named for its distinctive cluster of banana-shaped storage roots at the base. It sends up floating leaves and white flowers when mature. It is an unusual, undemanding midground plant that does not require substrate planting — it can float freely.
