Celestial Pearl Danios have an omnivorous diet, implying they feed on plant-based and animal-sourced foods. Their diet primarily includes small insects, aquatic arthropods, and algae in their natural habitat.
A balanced diet can be achieved in an aquarium setting by feeding them flake food, micro-granules, and freeze-dried or frozen brine shrimp and daphnia. Occasional feedings of live foods like baby brine shrimp or daphnia can also provide them with the necessary protein and different feeding stimuli, aiding in their health and vibrant coloration.
