Ember Tetra Care Guide Summary
The Ember Tetra, scientifically known as Hyphessobrycon amandae, belongs to the Characins family group. Adults reach a maximum size of approximately 2 cm and have a compressed body shape with a moderate growth rate. Classified as peaceful, this species primarily occupies the mid-level zone of the aquarium and produces a low level of biological waste.
To thrive, the Ember Tetra requires a freshwater only aquarium with a minimum volume of 38 litres and a tank length of at least 45 cm. Water temperature should be maintained between 23°C and 29°C, with a pH range of 5–7 and a general hardness of 1–10 dGH. A low water flow is preferred.
The Ember Tetra is a rewarding species to keep, provided its core environmental needs are met. The Ember Tetra is typically available in one standard form.
Ember Tetra Habitat Setup
When setting up an aquarium for the Ember Tetra, a low water flow best suits their natural preferences. Because this species occupies the mid-level zone, the aquarium layout should prioritise open swimming space in the centre of the tank for free movement. Useful additions include leaf litter or blackwater tannins to replicate their natural soft-water habitat and dense planting to provide cover, break sightlines, and reduce stress.
Ember Tetra Compatibility Notes
Classified as peaceful, the Ember Tetra is a schooling species that feels most secure in a sizeable group, where natural shoaling behaviour reduces stress and brings out their best colours. Selecting tankmates that favour different water layers from the mid-level zone can help reduce competition and territorial overlap.
