Cobalt Blue Angelfish

The Cobalt Blue Angelfish represents the pinnacle of domestic angelfish colour breeding for blue iridescence. Through generations of selective breeding for enhanced iridophore expression, this strain displays a deep, saturated cobalt-blue sheen across the majority of the body and fins, far exceeding the subtle blue highlights seen in most other strains.

Maintaining the cobalt blue intensity requires selecting only the most vivid fish for breeding over multiple generations. The intensity of the blue colour is also influenced by water quality, diet, and lighting — fish kept in optimal conditions with colour-enhancing foods and appropriate spectrum lighting will display the most spectacular colouration.

Cobalt blue angels are among the most sought-after domestic angelfish and typically command premium prices. They require intermediate-level care with attention to water quality and diet to maintain their exceptional colour.
