How to Identify GloFish

To identify GloFish (Gymnocorymbus ternetzi (modificado genéticamente)), look at these key features.

Physical Characteristics

Body shape

compressed

Coloration

Artificially vibrant, fluorescent colors including red ('Starfire Red'), green ('Electric Green'), orange ('Sunburst Orange'), blue ('Cosmic Blue'), purple ('Galactic Purple'), and pink ('Moonrise Pink'). These colors are due to the expression of fluorescent proteins. The base body shape is that of the Black Skirt Tetra, which is silvery-grey to black in its natural form, often with two or three vertical black bars on the anterior body.

Scale type

cycloid

Mouth position

terminal

Distinctive features

Intense, unnatural fluorescent coloration, Absence of natural pigmentation patterns (e.g., black bars are often obscured by the fluorescent color), Retains the deep, laterally compressed body shape of the Black Skirt Tetra

Dorsal fin

Single, relatively tall and triangular, located mid-body.

Tail fin

Forked, moderately sized.

Pectoral fin

Small, clear, located just behind the operculum.

Distinctive fins

Anal fin is notably long and deep, extending from behind the pelvic fins almost to the caudal peduncle, giving the fish a 'skirted' appearance, especially in the wild type. This feature is retained in GloFish.

2. 2

   Body Shape

   Deep, laterally compressed body with a long, skirt-like anal fin, characteristic of the Black Skirt Tetra.

3. 3

   Behavior

   Schooling behavior, active swimmers, generally peaceful in a group.
