Species Profile: Betta albimarginata
Common Name: Strawberry Betta, White Seam Betta
Description: A small but fierce maroon and black labyrinth fish with white-margined fins that lives in East Kalimantan blackwater swamps. Their colors intensify or fade to golden-brown depending on their mood and their environment, like tiny chameleons with a limited color palette. Betta albimarginata is closely related to Betta channoides, which is stockier than B. albimarginata and doesn’t have a white margin on its dorsal fin. CARES lists Betta albimarginata as Vulnerable, but the IUCN Red List lists it as Endangered.

Photo of aquarist's species:
Collection Point: Sebuku - East Kalimantan province on the island of Borneo, Indonesia
Genetic Line: F0 Wild Caught
Year Acquired: 2026
Acquired a group of 6 wild caught fish (3 pairs) from BW Aquatics in March 2026. They are currently housed in a 28g lowboy tank in blackwater conditions. The fish have done well, have spawned and at least one young fish has survived it's hard to know in the 36"x18" botanical and plant filled tank. In late June I was lucky enough to catch a pair spawning photo shows the pair while the female was exchanging the eggs to the male. When colored up they look like minature macrostoma!
