Non-red Devil Tetra Care Guide - Aquarium Setup, Diet & Breeding

The Non-red Devil Tetra is a small, active characin with a streamlined body, a forked tail and translucent fins. Its base colour is silvery to olive-brown, often with a dark lateral marking and subtle golden or copper tones. Compared with strongly red individuals sold as Red Devil Tetras, this form shows little or no obvious red in the body and fins.

These fish are lively but generally peaceful, spending much of their time in the middle levels of the aquarium. In a proper shoal they display more natural confidence and frequently engage in harmless chasing and displaying, particularly among males. They are best appreciated as a coordinated group rather than as solitary specimens.

In the wild, the species inhabits relatively shallow waterways with clear water, submerged roots, leaf litter and patches of aquatic or overhanging vegetation. Broken sunlight, cover and gentle current help create the varied environment associated with these small Brazilian streams.

The name “Devil Tetra” refers to the species’ energetic behaviour and striking appearance, not to an aggressive temperament. Non-red specimens are a naturally attractive alternative for aquarists who prefer a more understated South American tetra, although colour intensity can vary with genetics, mood and condition.

Hyphessobrycon piranga is native to Brazil in the upper Tocantins River drainage of South America. It occurs in small, clear, usually gently flowing streams and tributaries surrounded by forest and other vegetation.

A group of eight or more should be kept in an aquarium of at least 60 litres, with a footprint around 60 by 30 cm; a longer tank is preferable because these active swimmers use open horizontal space. Use a soft sand or fine-gravel substrate, add driftwood, roots, leaf litter and dense plants around the edges, and leave an open central swimming area. Floating plants or subdued lighting can make the fish feel secure, while gentle filtration and some water movement suit their stream habitat. Keep the aquarium mature, stable and well maintained, with a secure lid to prevent jumping.

Up to 4 cm (1.6 in) in standard adult length; females are typically slightly larger and deeper-bodied than males.

This species is an omnivore and does best on a varied diet of high-quality small pellets or flakes supplemented with frozen or live foods. Daphnia, baby brine shrimp, cyclops, mosquito larvae and finely chopped bloodworm provide useful variety and help maintain colour and condition. Offer small portions once or twice daily, ensuring that food is small enough for their narrow mouths and consumed promptly.

Non-red Devil Tetras are suitable for peaceful community aquariums containing similarly sized, calm fish. Good companions include small Corydoras, Otocinclus, peaceful rasboras, pencilfish, small non-aggressive tetras and gentle dwarf cichlids such as German blue rams when water conditions are compatible. Avoid large predatory fish, fin-nipping species and boisterous tankmates that may intimidate or outcompete them. They should not be housed with fish large enough to swallow them.

Non-red Devil Tetras are egg-scattering characins that can be bred in a separate, dimly lit breeding aquarium. Condition a group with plenty of live or frozen foods, then introduce selected adults to a tank containing fine-leaved plants or spawning mops. The female scatters adhesive eggs among the vegetation while the male fertilises them. Remove the adults after spawning, as they may eat the eggs. Hatching generally occurs within one to two days, with free-swimming fry ready for infusoria or other suitably tiny foods before progressing to newly hatched brine shrimp.

Females are usually fuller through the abdomen, especially when carrying eggs, while males tend to be slimmer and may show stronger colour and more pronounced fin development. Differences can be subtle, particularly in the less-red form, and are easiest to judge when mature fish are viewed together.
