Savage Tetra Care Guide - Aquarium Setup, Diet & Breeding

Savage Tetra, Hyphessobrycon savagei, is a small South American characin with the streamlined body and lively schooling behaviour associated with the Hyphessobrycon group. Its silvery body is accented by darker markings and translucent fins, giving the fish a subtle but attractive appearance that becomes more noticeable when it is settled and viewed as a group.

These peaceful fish spend much of their time in the middle levels of the aquarium, where they move together in loose, constantly shifting formations. They are active without usually being boisterous, and a properly sized shoal gives them confidence while allowing their social behaviour and natural displays to be seen.

In the wild, Savage Tetras inhabit clear to lightly stained waters in a region known for exceptionally high rainfall and dense tropical vegetation. Overhanging plants, submerged roots and leaf litter provide cover and create a broken pattern of light and shade in the shallow streams they call home.

The species is named in honour of the American ichthyologist Jay R. Savage. Although it is less commonly encountered than some better-known aquarium tetras, its modest size, peaceful nature and distinctive South American origins make it an appealing choice for a carefully planned community aquarium.

Savage Tetra is native to the Río San Juan drainage on Colombia’s Pacific slope in north-western South America. It comes from warm, freshwater streams and tributaries associated with the humid Chocó region.

A group of Savage Tetras should have at least a 60-litre aquarium, with a footprint of approximately 60 by 30 cm or larger. Use gentle filtration and provide open swimming space alongside dense planting, driftwood, roots and shaded areas that echo their forest-stream habitat. A dark, fine-grained substrate, leaf litter and subdued lighting can help bring out their colours, while a secure lid is sensible because small tetras may jump when startled.

Up to around 4 cm (1.6 inches) as adults; females are usually slightly deeper-bodied and may be marginally larger than males.

Savage Tetras are omnivorous micropredators. Offer a varied diet of quality fine flake or micro-pellets supplemented with small frozen or live foods such as daphnia, baby brine shrimp, cyclops and bloodworm. Small portions served regularly are preferable because their mouths are tiny and they naturally feed on small aquatic invertebrates and other organic food in the water column.

Savage Tetras are suitable companions for other calm, similarly sized community fish, including small rasboras, peaceful tetras, pencilfish, gentle dwarf corydoras and small, non-aggressive loricariid catfish. They should not be kept with large predatory fish, fin-nipping species or boisterous tankmates that may outcompete them for food or keep them permanently hidden.

Savage Tetras are egg-scattering characins that can be bred in a separate, softly filtered breeding aquarium. Use mature conditioned adults, gentle water movement and fine-leaved plants or spawning mops, with subdued lighting and protection for the eggs because the adults may eat them. Remove the parents after spawning; the eggs generally hatch within a day or two, and the tiny fry need infusoria-sized foods before progressing to larger foods such as newly hatched brine shrimp.

Females are generally fuller through the belly, especially when carrying eggs, while males tend to be slimmer and may display stronger colour or more extended fin rays. The differences are subtle and easiest to judge when mature fish are compared side by side.
