Flake food is recommended mainly as you can crush this up making it small enough however they can also have small frozen and live foods.
Community of similar size. They are least shy when shoaling in a group.
Intermediate. A dedicated tank with dim lighting will be required along with specific water conditions.
They can live to anything from 4-7 years in perfect conditions.
