In the aquarium trade, the most well-known being the Melanotaeniidae and the Bedotiidae. The most popular choice for aquariums fall under the family of Melanotaeniidae, known as the Pseudomugilidae genus. This species stays rather small, with the largest max size in a species being roughly 2". They are known as the "Blue Eyes" family because of one thing - their brilliant blue eyes. They are a peaceful family of fish that do their best while living in a group to feel safe and secure. Although they are peaceful, they are more suited to be housed with tank mates that are roughly the same size as them, as they may be more prone to shyness or being out competed for food. Rainbowfish are omnivores and should be fed a classic diet of meaty foods and algae-based foods.
