How big does Ember Tetra get?

Ember Tetra reaches an adult standard length of 1.5–2.2 cm (excluding the caudal fin). Size the tank for that, not for the juvenile you bring home — the difference is often several times over, and upgrading later costs more than buying once.

What water does Ember Tetra need?

23–28 °C, pH 5.5–7, 1–8 dGH. At 5 °C wide it is one of the more forgiving ranges.

What is the smallest tank for Ember Tetra?

At least 30 L, and no shorter than 40 cm. That is the floor for long-term keeping, not for short-term survival: volume buys water stability and length buys swimming room, and neither substitutes for the other. It is a schooling fish: keep at least 8 together. Fewer than that and it hides, loses colour, and aggression has nowhere to spread.

What is Ember Tetra like to keep?

Temperament: peaceful. Difficulty: beginner. It occupies the middle and is omnivore. With plants it is "Leaves plants alone".

Can Ember Tetra be kept with its most common tank mate?

The checker returns "Not recommended together". Ember Tetra and Angelfish is a recorded conflict in this atlas. Predation, territorial fighting or conspecific aggression is the usual outcome, and a bigger tank does not change it.

Keeping notes

1Adults are barely 2 cm, so a group of twenty fits comfortably in a 40 cm tank.
2Too small to share a tank with any fish that grows past 10 cm.
3Sensitive to swings: keep replacement water within 2 °C of the tank during changes.
4Alternating micro granules with live brine shrimp visibly deepens the color.
