I was asked recently why I selected angelfish when there are thousands of types of fish available in the aquarium hobby.
The answer is an easy one.
Once you realize you can tell one from another, it's easy to watch the behavior of each one. And by watching their behavior, you learn their unique personalities.
Yes, angelfish have personalities. Some are shy and others are outgoing. Some prefer to be alone while others want to emerge as leader. They can live to the age of ten years and when they mate, they mate for life. If one of the pair passes away, the other will often grieve themselves to death.
