Ember Tetra Care Guide: Hyphessobrycon amandae

Ember tetras are very small Brazilian social fish, with a maximum recorded length of 2.0 cm excluding the tail. Keep them only in a fully cycled, stable aquarium. We recommend a group of at least 10 and about 45 litres with a 45 × 30 cm footprint rather than using a litres-per-fish formula.
