Aurora Lizard Tetra - Iguanodectes variatus : Complete Fish Profile & Care Guide

Introduction

The Aurora Lizard Tetra (Iguanodectes variatus), a captivating freshwater species indigenous to South America, is renowned for its vibrant hues and elegant demeanour, making it a sought-after addition to community aquariums. With its striking appearance, this Tetra species elevates the aesthetic appeal of any aquatic display. With diligent care and an appropriate environment, these tetras thrive and provide enjoyment to aquarists of all skill levels.

Ideal for community tanks, Aurora Lizard Tetras thrive in mixed-sex groups comprising a minimum of 8 to 10 individuals. Their presence adds dynamic energy to the aquarium, especially when paired with other schooling fish like Tetras, Hatchetfish, Pencilfish, smaller Catfish, and compatible small-to-medium-sized Cichlids. Witnessing the captivating interactions among rival males as they compete for female attention or establish hierarchy within the group is both fascinating and enriching.

Creating an authentic habitat is essential for the well-being of Aurora Lizard Tetras. Utilizing river sand as substrate, complemented by natural rock and wood formations, offers a visually appealing landscape. Plants such as Amazon Sword, Hornwort, and Java Moss provide essential shelter, enhancing the natural ambience. Additionally, incorporating caves or rock structures provides stimulating hiding spots for these tetras to explore. 

The addition of dried leaf litter fosters a biofilm-rich environment, mimicking their natural habitat and contributing to their grazing behaviour.
Maintaining optimal water conditions is crucial, as Aurora Lizard Tetras are sensitive to water quality. Ensuring a well-decorated tank with ample hiding spaces and thriving vegetation fosters an ideal environment for these tetras to thrive. In return, aquarists are rewarded with the mesmerizing spectacle of their natural behaviour.

Characterized by silver to silvery-yellow base scales with light brown mottling on their sides and a brownish top snout, Aurora Lizard Tetras feature a reflective green lateral line and a dark stripe along the middle portion of their caudal fin.
