Salvinia minima - Mini water velvet

Salvinia minima (widely known as Mini Water Velvet, Common Salvinia, or Water Spangles) is a small, highly adaptable free-floating aquatic fern native to Central and South America. It has naturalized across many warm regions globally. Unlike its massive relative Salvinia oblongifolia, this miniature species is loved by aquarists and pond keepers for its tiny, round pads that form dense, quilted carpets across the water's surface, providing an exceptional natural filter.
