Guide to identifying GM fish

In this section of the website we aim to provide a general description of fish known to have been genetically modified for use in the ornamental aquatic trade including the common name(s) frequently used to describe GM variants of each species. The list will be expanded as the GM Inspectorate gathers further information about such fish.

Red danio (Danio rerio): Description – Identical to normal zebra/leopard danios except for the uniform and bright colouration across the whole body of the fish, varies in colour range from pink to red to orange. Bright colouration is visible under normal light, but fish will fluoresce under black/actinic light conditions (approximately 350-440nm).

Also marketed as: Coral pink danio, Purple danio, Neon danio, Dyed danio, Fluorescent danio, Coloured danio, TK2 danio.
