Appearance

Ember Tetras are small but stand out because of their glowing orange color. Their bodies are slim and slightly transparent, which gives them a soft, natural look in planted tanks.
Unlike larger tetras, they don’t have bold patterns. Instead, their beauty comes from their consistent color and how they move together in a group. In a well-lit planted aquarium, their orange shade becomes more vibrant, especially when they are healthy and stress-free.
Tank Size and Setup
Minimum Tank Size
A 10-gallon tank is enough for Ember Tetras, which makes them perfect for nano setups. However, if you want a larger group or a community tank, a 15–20 gallon setup works even better.

Best Tank Mates
Good Tank Mates
- Corydoras (small species)
- Rasboras
- Small peaceful tetras
- Shrimp and snails
These fish share similar temperament and won’t stress Ember Tetras.
Tank Mates to Avoid
- Large or aggressive fish

Because Ember Tetras are small and calm, they can easily get stressed.
Diet and Feeding
Ember Tetras are easy to feed but need small-sized food.
Best Foods
- Micro pellets
- Crushed flakes
- Baby brine shrimp
- Daphnia
Feeding Schedule
Feed them 1–2 times daily in small amounts. Make sure food is small enough for their tiny mouths.
Lifespan and Growth
Ember Tetras live around 2–4 years with proper care. They stay small throughout their life, making them ideal for nano aquariums.
Breeding Ember Tetras
Breeding Ember Tetras is possible in a home aquarium, but it requires a bit of setup since they are egg scatterers.
To improve success:
- Use a separate 5–10 gallon breeding tank
- Keep lighting low
- Add fine-leaf plants or moss (like Java moss)
- Slightly soft and warm water works best
Females release eggs while males fertilize them, usually early in the morning. After spawning, remove the adults immediately because they will eat the eggs.
Eggs hatch within 24–48 hours. The fry are very small, so start with infusoria or powdered fry food. After a few days, you can feed baby brine shrimp.
