Diet: Melanotaenia praecox is an omnivorous species that will thrive on a varied diet.

Tankmates: Dwarf Neon Rainbowfish are peaceful and community-friendly, making them an excellent addition to a variety of aquarium setups. They do well with other peaceful species such as tetras, barbs, small catfish (like Corydoras), and other rainbowfish. As schooling fish, they should be kept in groups of at least 6 individuals to help them feel secure and display their natural behavior. Due to their peaceful nature, they can be kept with a variety of other species, but avoid aggressive or fin-nipping fish. Providing a well-planted tank with open swimming spaces will allow them to feel comfortable and reduce stress.
