Serpae Tetra (Red Minor Tetra)
Hyphessobrycon eques
The Serpae Tetra or Red Minor Tetra (*Hyphessobrycon eques*) is an extraordinarily robust Characin with an incendiary color, characterized by a deep blood-red livery with a conspicuous comma-shaped (or rhombus-shaped) black spot just behind the gill cover. The fins, dark and bordered with a blinding white, are often held rigidly open in ritual threat poses, making the school constantly on display. Reaching 4 cm (1.5 inches) and possessing a very tall and compressed silhouette, it is a visually magnificent fish and almost indestructible in terms of water parameters. Nevertheless, it is notoriously famous in the aquarium hobby for being an unrepentant 'fin-nipper': if kept incorrectly, it will destroy the fins of any other slow or veiled tank mate.
