Blue Flash Glass Tetra - Heterocharax vigulatus : Complete Fish Profile & Care Guide

Introduction

Blue Flash Glass Tetras (Heterocharax vigulatus) represent a vivid and seldom imported Tetra species known for their vibrant colours and serene disposition. These Tetras exhibit a dynamic and robust nature, demonstrating their adaptability to various environmental conditions. 

Ideally, it is recommended to house them in groups comprising a minimum of six individuals, fostering a sense of security and camaraderie. Moreover, they can coexist harmoniously within a community aquarium alongside other small species of comparable size, such as Small Tetras, Micro Rasboras, and Celestial Pearl Danios.

To create an ideal habitat for these Tetras, it is essential to furnish the aquarium with ample aquatic vegetation, including roots, branches, and floating plants. This diverse flora provides abundant hiding spots, enabling the fish to engage in natural behaviours and seek refuge when needed. 

It is advisable to maintain a moderate water flow, coupled with effective filtration and oxygenation systems, to ensure the well-being of the inhabitants. Additionally, a subdued lighting setup is recommended to avoid excessive brightness. 

By employing a darker substrate, the stunning colours of the Blue Flash Glass Tetras can be accentuated, adding a captivating visual dimension to the aquarium.

The distinguishing physical attributes of these Tetras include an olive-grey body hue adorned with transparent fins. Prominently, two slender, iridescent blueish-green stripes grace the sides of their bodies. The first stripe runs parallel to the lateral line from the gill covers to the base of the tail, while the second, slightly curved stripe is situated below, extending from the eye to the tail base, with the latter portion being more pronounced. 

Under specific lighting conditions, these remarkable fish may also exhibit subtle purple nuances. Notably, the species features an adipose fin, a forked tail, a sizable and elongated anal fin, an upturned mouth, sharp teeth, and captivating large black eyes.
