Pacific Signifier Blue Eye Rainbowfish (Tank-Bred)

To protect our animals and to ensure they get to our customers healthy, we will only ship orders with Nano Fish via UPS Next Day Air.

The Pacific Signifer Blue Eye Rainbowfish (Pseudomugil signifer) is a popular and fascinating species in the aquarium trade, known for its iridescent beauty and peaceful nature. Pseudomugil species are smaller and often referred to as "blue-eyes" due to their characteristic bright blue irises.

We recommend keeping these guys in groups of 5 or more to achieve the best coloration for both males and females.

These fish are adult shrimp-safe, however, we recommend having sufficient plants or hiding spots for aquariums with both Pacific Signifer Blue Eye Rainbowfish and freshwater shrimp. 

Pacific Signifer Blue Eye Rainbowfish are pretty easy to care as long as they are introduced to a mature, cycled tank. They can acclimate to a wide range of parameters.  The following are our water parameters we keep them at:

Our Tank Water Parameters

GH: 7 to 8
KH: 3 to 4
TDS: 180 to 250

We feed them a mix of live baby brine shrimp, frozen daphnia and high-quality flake food.
