Red Tail Penguin Tetra

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.

Red Tail Penguin Tetra (Thayeria sp.) is a captivating and relatively recent addition to the aquarium hobby, known for its distinctive markings that resemble a raccoon's mask. 

Like most Tetras, we recommend keeping these guys in groups of 3 or more for them to feel safe in a larger school. They will look especially stunning in a planted tank.

Red Tail Penguin Tetr 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

PH: 7.2 to 7.5
GH: 7 to 8
KH: 3 to 4
TDS: 180 to 250
Temp: 72 to 75

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