Betta Albimarginata Wild Pair 2cm

The Betta Albimarginata (Betta albimarginata), known as the White-Seam Fighter, is a small and exquisitely beautiful wild Betta from the shallow, slow-moving forest streams of Borneo — particularly the Malinau and Sebuku river systems of Kalimantan, Indonesia. A paternal mouthbrooder, it is named for the distinctive white margins on its fins, which contrast beautifully against its rich red-brown body and iridescent blue-green scaling. One of the more manageable wild Betta species in terms of size, it is a wonderful choice for the intermediate to advanced keeper looking to explore the world of wild Bettas.
