Beginner verdict
A tiny, glowing orange schooling fish that stays peaceful and suits small planted tanks with soft, slightly acidic water. Keep a proper group of at least eight, because lone embers hide and lose color. It needs gentle flow, small foods, and calm companions, making it a rewarding early choice.

Ember Tetra care mistakes to avoid
The mistakes beginners most often make with this species.
- Do not buy just a few. Embers feel safe in numbers, and we recommend at least 8 fish.
- Avoid large or boisterous tank mates. Embers are outcompeted at feeding time and may stop coming out.
- Check your tap water first. Embers prefer soft, acidic to neutral water, up to pH 7.
- Add them only to a fully cycled tank. A fish this small has little tolerance for ammonia spikes.
- Choose foods small enough to fit their tiny mouths, because standard flakes and pellets are often too big.
Ember Tetra tank mates and swim zone
Mid-Water
Spends most of its time in this part of the tank.
Corydoras aeneus
Corydoras pygmaeus
Boraras brigittae
Otocinclus macrospilus
Planorbella duryi
Trichogaster chuna
Betta splendens
Embers are small enough for some bettas to hunt. Only try this in a larger, heavily planted tank.
Neocaridina davidi
Adult shrimp are safe, but embers will pick off baby shrimp. Add moss so the young can hide.
Barbodes semifasciolatus
Gold Barb is much larger than Ember Tetra and may frighten or even eat it.
Poecilia reticulata
Their pH ranges barely overlap, so you will have little room for error.
Puntigrus tetrazona
Too boisterous. Embers do not compete well with fast, nippy tank mates and will hide.
Carinotetraodon travancoricus
Puffers are nippy hunters, and a fish this small is an easy target.
Pelvicachromis pulcher
A larger, territorial cichlid that can eat fish as small as an ember.
Xiphophorus hellerii
Swordtail is big enough to eat or bully a fish as small as Ember Tetra.
Ember Tetra feeding and care
How to feed
- Feed crushed flakes or micro pellets small enough for a very small mouth.
- Add tiny live or frozen foods, such as baby brine shrimp or daphnia, for the best color.
- Give small portions and watch that shy fish get their share when faster tank mates are present.
Telling males from females
Adult males are more intensely colored, especially when ready to spawn. Females are noticeably rounder in the body.

Ember Tetra FAQ
What size tank do ember tetras need?
Seriously Fish suggests a base of at least 45 x 30 cm, which is about 11 US gallons (41 liters). Choose a longer tank if you can, because schooling fish benefit from swimming room.
How many ember tetras should I keep together?
Keep at least 8. Seriously Fish recommends a minimum purchase of 8-10, and larger groups look better and behave more confidently.
Are ember tetras safe with shrimp?
Adult shrimp are generally safe. Baby shrimp may be eaten, so dense moss gives the young somewhere to hide if you want the colony to grow.
Will ember tetras live in my tap water?
They do best in soft water from pH 5 to 7, up to about 10 dGH. Test your tap water first. If it runs much harder, choose a species suited to it instead of chasing the numbers with chemicals.
