Here's the breakdown of the scientific classification for zebrafish:
* Kingdom: Animalia (Animals)
* Phylum: Chordata (Chordates)
* Class: Actinopterygii (Ray-finned fishes)
* Order: Cypriniformes (Carp-like fishes)
* Family: Cyprinidae (Carp family)
* Genus: Danio
* Species: rerio
Therefore, all "glow fish" belong to the species Danio rerio. The fluorescent protein expression is a genetic modification, not a distinct species classification.
