It mainly covers the states of Mato Grosso, Goiás, and Tocantins of Brazil.
The IUCN Red List of Threatened Species assessed the fish last in 2018 and enlisted it as Least Concern.
Which family foes Ember Tetra belong?
The fish is classified under the order Characiformes and the family Characidae. Scientifically, it is known as Hyphessobrycon amandae.
Commonly, it is known by many names like ember tetra, fire tetra, dwarf red tetra, and red tetra.
It also has an interesting name: Amanda’s tetra. The founder of this fish, Heiko Bleher, named it after his mother, Amanda Bleher.
Fun Fact: When the fish swims around in groups in the tank, it looks like a bunch of orange bullets or darts.
How does Ember Tetra look?
The fish has a bilaterally symmetric body shape similar to most tetras. Now, let’s know about some other intriguing features.
What is the Size of Ember Tetra?
The fish grows at most to 2.0 cm (0.8 in). However, captivity may stunt its growth to 1.5 cm (0.6 in).
What is the Color of Ember Tetra?
Its body has a reddish-orange shade with slight translucent areas around the pelvic fins. Due to their translucency, they seem to glow like fire in light.
The dorsal fin has a gradient that fades from the primary shade to something darker towards the back. Its dorsal fin has a black tip.
The base of the caudal fin is the same color as the body or even brighter. It transitions further into a darker orange shade and then slowly turns transparent near the back half of the fin.
Its ventral and pectoral fins are almost transparent. The eyes are black with an orange outline.
However, the brightness of this color varies with age, diet, and even stress.
What are the Features of Ember Tetra?
The fish has tall and thin dorsal fins and forked caudal fins. It also has a hearing range of 200-2000 Hz and a 70 dB hearing threshold.
How can you differentiate between Male and Female Ember Tetra?
The adult male fish is way more brilliantly colored than the females. During spawning season, males show even more prominent bright colors, and females become rounder. Females also have a larger swim bladder, which adds to their round shape.
How does Ember Tetra behave in an aquarium?
It is a peaceful shoaling fish, i.e., it prefers to swim around in a group of its own species. It never creates trouble with tank mates. Instead, it gets intimidated by bigger and fiercer tank mates and hides from them.
How long does Ember Tetra live?
With great care and a well-maintained tank environment, the fish may live for 4 years. But in my experience, lack of enough vegetation in the tank and care reduces their lifespan to 2 years.
Author’s Note: Though the fish is quite social, it rarely shows fin-nipping behavior. If your pet fish does the same, it’s because of the small group. You must add more ember tetras in this case.
How to take care of Ember Tetra?
Now, let’s learn to prepare the perfect cozy and safe house for your pet fish.
What is the Tank Size for Ember Tetra?
Since it is a shoaling species, you need to keep 10 conspecifics (same species) together. To house them all, a minimum of 20-gallon tank is required.
Increase the tank size if you wish to add more conspecifics or other tank mates.
What should be the Water Chemistry for Ember Tetra?
The fish’s health depends a lot on water conditions, so you can keep them free of diseases with –
- pH Levels: 6.0-7.5
- Water Temperature: 70-82 °F (21-28 °C)
- Water Hardness: 4-17 dGH
- Carbonate hardness: 3-12 dKH
- Ammonia: 0 ppm
- Nitrite: 0 ppm
- Nitrate: Below 30 ppm
What is the Tank Environment for Ember Tetra?
A healthy fish is not JUST about water. If you want to sustain it for long, you must also provide it with a good environment, which includes:
Do Ember Tetra like to have Substrate in aquarium?
They aren’t picky between sand or gravel substrate. However, choose a dark-colored substrate since they are seen more in blackwater tributaries.
Do Ember Tetra need Plants in the aquarium?
Keep your embers in a heavily vegetated tank, allowing them to hide and resting place and cover from light. It also makes an incredible egg depositing site as it can keep it hidden from others. Floating plants like Salvinia are a great option.
What Lighting is needed in the Ember Tetra tank?
Moderate to dim lighting will help the fish feel safer.
What Décor is needed in Ember Tetra tank?
To mimic the Amazonian acidic blackwaters, add dry beech, oak, or catappa leaves and driftwood to stain the water with tannins. However, change the wood and leaves regularly to avoid rotting.
What type of Filter is needed for Ember Tetra tank?
Use a gentle powered filter in the tank that has a sponge-styled unit.
What should be the Water Flow Rate for Ember Tetra tank?
The fish enjoys a slow water movement rate.
Fish Care Tip: Some aquarists say adding more plants can increase ember tetras’ longevity to 10 years. However, that’s false, so keep only a limited number of plants. Don’t overcrowd the tank and leave space for swimming.
Clean the filter media monthly and perform partial (30%) water changes weekly.
What do Ember Tetra eat?
It is not a picky eater and can thrive on various diets like pellets, frozen, freeze-dried, and flake feed. Variety is essential to sustain it for longer.
Always keep live feed in its diet as it helps maintain its bright color. Some are:
- Microworms
- Tubifex
- Daphnia
- Rotifers
- Cyclops
- Fry and small fish food
- Finely chopped bloodworms
- Brine shrimp
It enthusiastically consumes any small feed or even species.
Don’t feed them a lot at once to avoid bloating. Instead, provide them thrice a day.
What are the Tank Mates for Ember Tetra?
Its best buddies are schooling fish of similar size, like neon tetras, livebearers, and rainbowfish. Neon and ember tetras may even join to form one school.
Since this species swims in the middle to top levels, you can keep it with peaceful and small bottom-dwelling fish like pygmy corydoras and loricariids.
If you want to choose any other tank mate, make sure it is peaceful and smaller than embers. Some examples are:
- Harlequin rasboras
- Guppies
- Danios
- Cardinal tetras
- Glowlight tetras
- Bolivian rams
- Black skirt tetras
- Longfin albino bushynose plecos
- Dwarf cichlids
- Hatchetfish
- Otocinclus catfish
- Pencilfish
- Similar-sized shrimps
- Nerite snails
Which Tank Mates to Avoid for Ember Tetra?
Never keep aggressive and bigger fish in a tank with ember tetras. Some aquarists say gouramis can make good tank mates, but they may also act territorial. So, don’t take such chances. You must also avoid:
- Larger cichlids
- Bettas
- Large barbs
- Oscars
Don’t house invertebrates that can fit in this fish’s mouth. Otherwise, they will become food for it.
What are the Common Diseases for Ember Tetra?
The fish is hardy and can resist many diseases, but you must be careful about the following.
Disease Name | Causes | Symptoms | Treatment |
---|---|---|---|
Ich | Protozoan parasite | Flashing, white raised spots, appetite loss, lethargy | Tank water temperature elevation, aquarium salt or ich medicine adding |
Columnaris | Bacterial infection | White to grey patches, fin fraying, appetite loss, lethargy | Enhanced water quality, antibiotics, reduced stress |
Fin and tail rot | Bacterial infection or excess waste in the tank | Frayed and reddened fins, white spots, flesh rotting, redness, swelling, lesions, appetite loss, lethargy | Enhanced water quality, physical injury sources removal, antibiotics (malachite green), stress reduction |
Skinny disease | Viral infection | Reddened anus and/or belly, scale loss near fins, appetite loss, high activity, weight loss | No particular treatment. But try antibiotics |
Swim bladder disease | Bacterial infection, high nitrate concentration, sudden temperature change | Fish floating on the tank surface, swimming in curves, sideways, or upside down | Antibiotics, water maintenance, avoid feeding for 3 days, feeding cooked and skinned peas after 3 days, and temperature fixing |
Pop eye | Immune Response from Injury | Protruding and swollen eyes | Water changes, quarantining, salt addition, balanced diet, antibiotics |
Impaction | Excess dry food consumption, overfeeding, parasitic infection | No bowel movement, appetite loss, bloating, lethargy, discoloration, rectal prolapse | Reduce feeding amount and frequency, water quality enhancement, fibrous diet, stress reduction, medicine |
Neon tetra disease | Microsporidian parasite | Restlessness, color loss, lumpy flesh, swimming difficulties, curved spine, bloating, fin rot | Incurable Try treating with methylene blue |
Important points to keep in mind:
- Though the fish needs live feed, try cultivating your own instead of buying from outside. Otherwise, parasites may get introduced to tetras through live feed making them sick.
- Always quarantine ember tetras before adding them to a tank with existing fish.
How to breed Ember Tetra in an aquarium at home?
The species is pretty easy to breed as they spawn even without external stimulation. You can still induce spawning by maintaining a temperature of 80 °F (27 °C) or higher and a neutral pH.
What should be the Tank Preparation for breeding Ember Tetra?
It’s hard to make the fry survive as the parents aren’t protective, and they often become food to other fishes. So, build another tank (5-10 gallons) specifically for breeding with mature water. Maintain water chemistry at:
- Temperature: 81-84 °F (27-29 °C)
- pH: 5-7
- Water Hardness: 1-5 dGH
Use soft lighting and spawning mops for egg laying. Add a thin layer of a dark substrate.
How do Ember Tetra Mate?
House a group or mated pairs in there. Choose equal numbers of round and thick females and the most brightly colored males (if you’ll keep them in pairs).
In favorable conditions, female fish lay eggs, and male fish follow behind to fertilize the eggs.
By the next morning, spawning will occur. When you notice eggs, shift the parent fish back to their original tank.
How does the Fry Development of Ember Tetra look?
Avoid any lighting during the incubation phase (24-48 hours). Once the fry starts swimming freely, feed them infusoria, home-cultivated chopped brine shrimp, or high-quality fry food.
As the fry grows, adjust the water chemistry similar to that of the tank with parent fish.
Breeding Tip: It’s difficult to check for eggs in the spawning tank as they are transparent and tidy. So, make sure you notice the tank closely. If you miss the eggs and let the parent fish stay in the breeding tank, the fry may get eaten.
What are the Buying Tips for Ember Tetra?
Since a balanced diet can improve the color of this species, beginners often overfeed their new pet fish. This may lead to health concerns. So, while buying this fish, ask the seller about the meal portions and frequency.
