If you’re looking for a beautiful fish, get some ember tetras! These fish are stunning!

These fish are a great touch to almost any aquarium.

Usual Behavior

Ember tetras are a schooling fish, so I recommend getting at least a school of 6 or more.

They are peaceful fish and unlikely to be the bully of the aquarium.

Lifespan

Expect these little guys to live up to three years. Remember to care for these fish properly so they can live as long as possible.

Size

Ember tetras don’t even get an inch long (about .75 inches in length), so will never need a large aquarium. That doesn’t mean they can live in tiny aquariums though.

Ember Tetra Care

Okay, now that we know a little bit about these fish, it’s time to learn how to care for them. Always keep any fish you have to the best of your ability so they will live a long, happy life.

Tank Size

Saying that these fish don’t get even an inch long, they can easily live in a 5 gallon aquarium. But, many aquarists recommend keeping these fish in a 10 gallon tank.

How Many Ember Tetras For A 10 Gallon?

I’d say for every gallon of water you have, you can have one ember tetra. So, for a 10 gallon tank, you could keep about 10 fish.

I suppose you could also have a few more saying how small they are, but make sure that you don’t overstock your tank!

Tank Mates

These fish really aren’t that aggressive, so just make sure that these fish are kept with other peaceful fish that are around the same size. You can keep neon tetras, guppies, and danios along with these fish.

Remember to never keep any large and/or aggressive fish with ember tetras, or else they might turn into a snack!

Diet

Saying that these fish such tiny mouths, it might be a little hard finding food to feed these fish.

You could always feed your ember tetras live foods like baby brine shrimp, vinegar eels and baby daphnia.

If you can’t feed these fish live foods all the time (which I understand), then I recommend feeding adults (not ember tetra fry) some fry food.

Yes, ember tetras are so small that they should be fed fry food when they’re adults, not fry.

Water Parameters

Make sure that the parameters in the water are stable. Unstable water parameters can make the fish stress which will make them susceptible to diseases!

  • pH: 5.5-7.0
  • Temperature: 68-82 Fahrenheit or 20-27.7 Celsius)
  • Hardness: 1-10 dKH

Possible Diseases

They’re pretty hardy, but that doesn’t mean they never get sick. Watch out for the following diseases and health conditions.

  • Bloat
  • Ich/White Spot Disease
  • Constipation

Typical Price

The online stores I visited sold them for just about 2-3 dollars an individual. So, they aren’t super expensive.

What Do Ember Tetras Eat?

Breeding Ember Tetras

Breeding ember tetras shouldn’t be that hard. But, there are a few things you need to know.

First of all, ember tetras don’t care for their fry. So, make sure you have a separate tank for them.

In the breeding tank, you’re going to need softer water. A pH of 6.5-6.8 should do. The temperature should be fairly warm; the water should be 73-79 degrees Fahrenheit.

Remember to feed these fish well. The tank should be filled with plants and hiding places for the fish.

Once they have bred (note that the mating ritual is subtle, so may not catch it), separate the parents and the eggs.

The eggs can take 1-2 days to hatch. The fry should grow pretty quickly.

Are Ember Tetras For Me?

The ember tetra is a small, colorful, fish that should brighten up just about any aquarium.

These fish are peaceful and easy to care for, just remember that if you are planning on them having tank mates that they aren’t too large.

So, if you’re looking for a small, beautiful fish that doesn’t need a large aquarium, then perhaps they are.

If you can’t have ember tetras but like their look, I recommend getting some chili rasboras.
