Helanthium bolivianum 'Latifolius'
Bronze Featherback
Notopterus notopterus
Brown Ghost Knifefish
Apteronotus leptorhynchus
Brunei Beauty
Betta macrostoma
Bryopsis
Bryopsis sp.
Feathery, fern-like dark green algae that is notoriously difficult to eliminate — one of the most persistent reef tank nuisances. Resistant to most herbivores. Best controlled by raising magnesium to 1500–1800 ppm for 2–4 weeks (magnesium treatment). Sea hares will consume it but are not a permanent solution.
Bubble Algae
Valonia ventricosa
Iridescent green spheres that appear harmless in small numbers but rapidly colonise rock if left unchecked. Emerald crabs are the most effective biological control. Do not pop bubbles — they release spores and worsen the outbreak. Manual removal requires extracting the entire holdfast; even fragments regrow.
Bubble Coral
Plerogyra sinuosa
Bubble Eye Goldfish
Carassius auratus
Bucephalandra
Bucephalandra sp.
A genus of slow-growing rheophytic plants native to Borneo, prized in aquascaping for their thick, waxy leaves that come in a remarkable range of colors — from green and brown to blue, purple, and red — often with iridescent shimmer. They can be grown attached to rocks or driftwood like Anubias, tolerate low to medium light without CO2 injection (though CO2 accelerates growth), and are well-suited to shrimp tanks.
