General: The giant danio originates from highly oxygenated streams in India. It is a very outgoing fish that will add a lot of activity to the home aquarium. When setting up the giant danio's aquarium, consider using a gravel substrate with different sized rocks, creating a moderately strong current in the water, and incorporating driftwood and plants if possible. These fish like a lot of open space to swim. There is the chance they can jump out of the aquarium, so be sure to cover up all openings on top of the aquarium.
Fecundity: The giant danio will scatter its eggs, and after spawning the adults should be separated to ensure the eggs will not be eaten. It is wise to have some sort of medium such as a layer of aquarium plants that the eggs can fall into to provide protection. The eggs will hatch within one to two days and the fry will be extremely small. They will require infusoria and eventually can be transitioned to live baby brine shrimp.
Water Chemistry: Giant danios prefer a water temperature that ranges from 72-75F, a KH that ranges from 8-12, and a pH that ranges from 6.0-7.0.
Aquarium Diet: Giant danios are naturally omnivores, but to encourage them to spawn they need to be fed high quality protein-rich foods such as blood worm and brine shrimp. They also will accept fish flake.
Dimorphism: Female giant danios are typically larger than males and are more pale in color.
Compatibility: Giant danios can be housed with peaceful cichlids, loaches, cory catfish, tetras, and larger rasboras. Avoid fish that have a tendency to get nervous or have long fins. Also, giant danios are a social species and need to be kept in a school of at least six individuals.
