Betta imbellis

The Peaceful Betta, also known as the Crescent or Dwarf Betta, is a great choice for aquarists looking for the beauty of a betta without the extreme aggression. Unlike its more famous cousin, the Siamese Fighting Fish, this species can be kept in small, mixed-sex groups in a well-planted aquarium. As its name suggests, it is more tolerant of tank mates, though males will still show some territorial behavior by flaring their fins. This is a small Asian fish that thrives in calm water with plenty of hiding spots among plants and wood. Because it naturally breathes from the surface and is a known jumper, a secure lid on the aquarium is absolutely necessary. It is a carnivore, meaning it needs a meat-based diet. A mix of high-quality betta pellets, along with frozen or live foods like brine shrimp or daphnia, will keep it healthy and vibrant. While not overly demanding, its need for specific group housing and a carefully set up environment gives it a medium difficulty rating, making it better suited for someone with a little prior fish-keeping experience. With proper care, you can enjoy these beautiful fish for several years.
