The Red Neon Blue Eye Rainbowfish is a peaceful fish species and can be kept with similar size fish. Best colors will be displayed when this fish is kept in schools of 6 or more, including multiple males. As with many rainbowfish, darker substrate will also often result in better coloration. While this fish will accept high quality flake foods, it should also be fed plenty of small frozen or live foods for optimal health and coloration. It likes temperatures from 18° – 26° C, a pH between 6.5 – 7.5, a KH of about 10 and is suited for nano tanks about 30 litres. It is omnivorous. High quality dry foods will be accepted, but should be supplemented often with small, meaty frozen and live foods.
