Blue Alien Bettas (Hybrid of Betta splendens)

Blue Alien Bettas are a stunning captive-bred hybrid derived primarily from Betta splendens and related wild species. Blue Alien Bettas are known for their intense, iridescent blue coloration and metallic, mask-like facial pattern. These short-finned plakat-style bettas combine wild-type structure with vibrant metallic shine, making them highly desirable for planted aquariums.

They are hardy, active swimmers that adapt well to properly maintained home aquariums. Blue Alien Bettas prefer calm environments with plants and hiding areas to feel secure.
