About the Peaceful Betta (B. Imbellis)

The scientific name of the species is Betta Imbellis, as described by Werner Ladiges in 1975. The Imbellis has metallic blue-green gill plates that reflect beautifully in the light. Typically, the average size of an Imbellis is between 1.5 to 2 inches long. While males tend to be bigger than females, they also tend to be more colorful and have more extensive fins.
The B. Imbellis is a cousin to the most popular fish species in the aquarium hobby—the Betta Splendens. Also known as the Siamese Fighting Fish, they are commonly sold in undersized containers at pet stores.
In appearance, the B. Splendens generally have larger fins and slightly brighter in coloration. Nevertheless, the two species are physically very resemblant. It is in temperament that two species differ most. For the most part, the Imbellis remains peaceful in a community aquarium. The Splendens, on the other hand, are notoriously belligerent with other fish.
