Spotted blue-eye

Pseudomugil gertrudae

Blue eyes and spotted fins, with colours that vary between populations.

Adult length: Up to 3.8 cm (standard length, without the tail fin)
Water temperature: 25–30 °C
pH: 6
Hardness: 5–12 dGH

Natural habitat: Inhabits creeks, swamps, shaded rainforest streams, lily lagoons and backwaters, often over mud with abundant plants and submerged wood.

Appearance and identification

The adult male emphasises spots on the second dorsal, anal and tail fins. Compare the spotted fins and shorter tail outline with the forktailed blue-eye’s deep yellow-and-dark-edged fork. Blue eyes alone do not identify either species.

Diet and feeding

Offer varied, appropriately sized food, with supplementary live food. Breeding works around 27°C and pH 7.
