Ember Tetras are beautiful red/orange freshwater fish that can be kept as a pet. They are perfect choices for nano fish tanks due to their small size. They’re peaceful schooling fish that greatly add to most community aquariums. This fish species is excellent if you’re looking to fill your aquarium with tiny fish. This guide will cover Ember Tetra care. It will discuss this specie’s aquarium requirements, food & diet, compatible tank mates, and breeding habits.
Aquarium Requirements
Ember Tetras are very peaceful fish that stay very small. They will be about an inch in length when fully grown. This makes them excellent candidates for nano aquariums as a centerpiece schooling fish or a schooling fish that blends into the background of a large aquarium. A well-planted aquarium with various rocks and driftwood makes the perfect enclosure for Ember Tetras.
How Many Ember Tetras in a 10 Gallon Tank?
A minimum of 6 fish are recommended to be considered a school. You should be able to successfully keep between 10 to 15 Ember Tetras in a 10-gallon fish tank. The max size of Ember Tetras and their incredibly small bio load gives you some flexibility regarding population sizes in a fish tank.
Water Parameters
Learning the water parameters for your aquarium is important to its success. Fish like the Ember Tetra are found in the tropical waterways of South America. This type of water is much different than what can be found in Lake Tanganyika, which has much harder and calcium-rich water. The following are water parameter ranges that will help you successfully keep Ember Tetras.
Temperature: 72° – 77°F
pH: 5.5 – 7.0
Water Hardness: 4 – 8 KH
Based on the water parameters you can see that Ember Tetras do best in softer and acidic water. Some homes have naturally soft and acidic water, but there are many homes such as ones with wells that do not. Often well water is rich in calcium and other minerals that cause a spike in pH levels and hardness. An easy way to test for this is through the use of an aquarium test kit. I recommend purchasing an API Freshwater Master Test Kit and API GH & KH test kit. With these test kits, you can keep an eye on your aquarium’s pH, General Hardness (GH), Carbonate Hardness (KH), ammonia, nitrites, and nitrates.
Food & Diet
Ember Tetras stay incredibly small, they may not be able to consume the large fish food that is often provided. They will do great with frozen daphnia, brine shrimp, and Mysis Shrimp. Traditional pellet food may be a little large for them to consume, so I recommend feeding them Ultra Fresh Tropical Micro Pellets and flake food such as New Life Spectrum All Purpose Flake Food. In the wild Ember Tetras eat a variety of foods so it is important to provide the same experiences in the aquarium.
Tank Mates
Ember Tetras, like most peaceful fish, will do fantastic with most other peaceful community fish. Keeping them with Tetras, Rasboras, Corycats, Honey Gouramis, Endlers Livebearers, Guppies, and other community species, should be successful.
Due to their size, I would not recommend keeping Ember Tetras with large fish, fish with large mouths, and fin nippers. Their small size and peaceful temperament do not allow them to hold their own against more aggressive fish. You will want to keep them with community fish that will not harass Ember Tetras.
Breeding
A large enough school will provide you with both males and females. In a well-established and healthy aquarium, Ember Tetras should breed on their own without much intervention. However, getting eggs to hatch before getting eaten and having your fry develop into adulthood will be the challenge.
Ember Tetras scatter their eggs throughout the aquarium after spawning. The eggs are adhesive and will stick to many different surfaces in the fish tank. To provide the best chance for the eggs, a heavily planted aquarium will be needed to provide hiding places for the eggs to adhere to. I recommend many different plant species, especially things like java moss that grow dense which may create cover for eggs. A lot of plants will also benefit from providing cover for the fry once they hatch.
Eggs and fry are likely to get eaten by most other inhabitants of the aquarium. Keeping your Ember Tetras in a species-only aquarium will help cut down on the die-off. For more information on breeding, check out real life experiences of breeding Ember Tetras on Fishforums.
Final Notes
If you enjoy nano fish tanks and micro fish, Ember Tetras might be an excellent choice for you. They are small, stay small, have a nearly non-existent bio-load, and generally are great fish to keep. Their red/orange colorations will pop in a well-planted aquarium and maybe just the final touch you need for your fish tank. If you’re not sold on Ember Tetras, consider checking out other Red Tropical Fish for your Freshwater Fish Tank.
Freshwater fish come in many different colors, shapes, and temperaments. There is a red freshwater fish to fill every niche in this hobby whether you want to fill a planted community tank or a large aggressive predatory aquarium. This guide will discuss some fantastic red tropical fish that are available for freshwater aquariums. As a disclaimer, I will not be covering a lot of the care needed for these fish, but I will showcase the many different species out there.
1. Cherry Barb
Cherry Barbs are beautiful freshwater fish and are first on this list of red freshwater fish. Unlike many other barbs, this is a very peaceful fish that will do great in a freshwater community tank. The males usually showcase a dark red color, which becomes a vibrant cherry red when breeding, and females are usually a mixture of brown and dull red.
How Many Cherry Barbs in a 10 Gallon Tank?
I personally would not recommend keeping Cherry Barbs in a 10 Gallon Tank. I would recommend for aquariums that are 20 gallons or larger. Although they do not tightly school, it is recommended to keep them in groups of 5 or more. On top of that, this species of fish enjoys exploring the whole fish tank. A 10 gallon aquarium does not provide enough space for your Cherry Barb to explore.
How Big Do Cherry Barbs Get?
Cherry Barbs get to about 2″ when fully grown. They do not get very large so they should not dominate other community fish during feedings.
2. Ember Tetra
Ember Tetras are beautiful little fish with vibrant red colors, that do great in freshwater aquariums. Similarly to many other tetras, this species does best in groups. This species is great if you’re looking for a very small fish to add into a freshwater aquarium. They should not get larger than 1″ when fully grown. They’re very peaceful and will keep to themselves so they will be great in a species aquarium, or a community fish tank with similarly sized fish.
How Many Ember Tetras in a 10 Gallon Tank?
If you’re just keeping only Ember Tetras in your aquarium, you should be able to stock the fish tank with about anywhere between 8 and 14. Someone with more experience, excellent water conditions, and a fish tank full of plants will likely keep 14 successfully. On the other hand, I would recommend 8 if you’re newer to fishkeeping or don’t always keep up with water changes/keeping water parameters in check.
How Many Ember Tetras in a 20 Gallon Tank?
Ember Tetra size and small bio-load allow you to stock a 20-gallon with anywhere between 16 and 24 individuals. Like a 10-gallon, a well-kept aquarium should hold 24 individuals. 16 Ember Tetras are recommended for aquariums that may have a few other fish or that may not always have the best water parameters. Every aquarium is unique, so I cannot definitively answer how many fish can be kept in a fish tank. These are merely suggestions.
3. Red Phantom Tetra
If you love Ember Tetras but want something that’s a little bigger, then you have to check out Red Phantom Tetras. The Red Phantom Tetra is slightly transparent with different red tones on its body. This species grows to about 2″ as an adult, and will do great in aquariums that are 20 gallons or larger. Like many other tetra species, Red Phantom Tetras do best in schools of 6 individuals or more.
How Many Red Phantom Tetras in a 10 Gallon Tank?
To have a properly sized school, I would not recommend keeping Red Phantom Tetras in a 10-gallon tank. A 20-gallon or larger will be more suitable for this fish species. The extra aquarium space will allow you to keep anywhere between 6 and 9 Red Phantoms.
Can I Keep Red Phantom Tetras with Shrimp?
Red Phantom Tetras should not normally bother adult shrimp. However, they may try to make a snack out of recently molted shrimp due to them temporarily having a soft body. Also, baby shrimp may become food for this species of fish. If you are interested in keeping shrimp with Red Phantom Tetras, consider providing many hiding places and heavily plant your aquarium to provide cover for your shrimp.
4. Betta Fish
Betta fish come in a wide assortment of colors. There are fully red bettas or betta fish with red mixed with different types of colors. There is a choice for pretty much anyone. Also, Betta fish are fantastic fish to have due to their wonderful personalities. I have seen aquarists go so far as to teach their betta tricks. I will cover a few things about bettas below, but consider checking out the Betta Complete Care Guide for more information.
How Long Do Betta Fish Live?
A Betta Fish can live anywhere between 2 and 5 years. Excellent water parameters and a properly sized aquarium should help this fish live a stress-free life which should help it live longer.
Do Betta Fish Need a Filter?
From personal experience, I do recommend providing a filter for your Betta Fish. The filter, whether it’s a Hang-on back or sponge filter, holds a lot of beneficial bacteria that help keep your water parameters stable. Although bettas can acquire oxygen from the atmosphere, filters will assist in oxygenating your water to make your life easier for your fish.
There are a few things to keep an eye on when running a filter with a Betta Fish. The biggest is probably the flow rate, especially in smaller aquariums. Many Bettas have long showy fins, and a filter with a high flow rate can toss the fish around. This can damage the fish’s fins and stress it out. You may see this happen more often with hang-on back filters. Also, a hang-on back filter’s suction could potentially be deemed a hazard for your fish. I feel a healthy fish should not generally get caught in a filter’s suction, but a Betta Fish has long fins that may get pulled in.
I recommend using either a sponge filter for a betta fish tank or putting a sponge over the filter intake to slow the flow of water. If you cover the intake, debris may build up on the sponge, which will need to be cleaned out from time to time.
5. Red Blood Parrot
Blood Parrots are hybrid fish made from breeding certain types of cichlids. They have gotten a lot of popularity due to their unique shape and vibrant red colorations. They can grow to about 8″ and will do best singularly in a 30-gallon aquarium. If you would like to keep more, keeping them in groups of 3 or more is recommended. However, you will also need a larger fish tank to house more Blood Parrots. Keeping a pair will likely cause one to be much more dominant and aggressive toward the other.
Are Blood Red Parrot Cichlids Aggressive?
From experiences with Blood Parrots, they can be aggressive, but they are much less aggressive than other cichlids like Jack Dempsey, Convict Cichlid, or Oscar. They can hold their own and are sometimes kept with Oscars and will also do well with Angelfish, larger Tetras, and other Blood Parrot Cichlids.
Can African Cichlids Live with Blood Red Parrots?
I would not recommend keeping African Cichlids with Blood Parrots, due to the Blood Parrot’s docile nature. Also, Blood Parrot Cichlids are more commonly kept in planted aquariums because they do not destroy plants or dig in the substrate like many other cichlids do, and prefer more acidic and softer water.
6. Red Oscar
Red Oscars are a gorgeous species of cichlid that has a variation of colors on its body, with vibrant red being one of them. As beautiful as they are, this species of fish is not for everyone, due to their large size as adults. Working with fish for most of my life, I have seen vast amounts of neglect on Oscars (and other fish) due to improper husbandry. If you love large species aquariums and are on top of filtration/water changes, consider picking up a Red Oscar Cichlid.
Are Red Oscar Cichlids Aggressive?
Yes, like most other cichlids, the Red Oscar fish is an aggressive species. They are also a larger species of cichlid and grow to around a foot long. Due to this size, they should be kept in aquariums that are 75 gallons or larger for one Oscar fish. If you are interested in keeping two, they will likely need anywhere between a 125 or 150-gallon aquarium. If you’re looking for common aquarium sizes, check out some Standard Aquarium Sizes.
7. Red Honey Gourami
The Red Honey Gourami is a great addition to a community tank. They are usually a dull red/yellow color that stands out from a planted aquarium background. This fish can do well in a 10-gallon aquarium singularly, but a group of 3 can be kept in 20-gallon aquariums. They’re an excellent choice if you have a nano aquarium, or are looking for a single fish that does not need to school.
Are Red Honey Gouramis Aggressive?
Red Honey Gouramis should not be aggressive. This species of fish may become shy if there are highly active or semi-aggressive fish in the aquarium.
8. Red Livebearers
For the sake of this article’s length, I am grouping Mollies, Platies, Guppies, and Swordtails into just livebearers. They all come in many different flavors but each can be found with red colorations. Each of these fish should do well in community fish tanks. Guppies are the smallest livebearer fish in this group, with males having long flowy fins.
As a disclaimer, live bearers do just that, they have live offspring. If you are not careful, they may plague your aquarium with offspring which may become a headache to control.
9. Red Irian Rainbow
Red Irian Rainbow Fish is next on this list with their vibrant red, orange, silver, and gold coloration. Their colors pop the most when there are both males and females in the aquarium. This Red Rainbow Fish does well with a combination of both densely planted and open swimming areas.
Aquarium Size for Irian Red Rainbow
This species of fish will grow to be about 4-5 inches, and on top of that they’re schooling fish. I would recommend keeping them in at least a 55 gallon aquarium to provide optimal space. You may get away by starting them off in a 30 gallon, but eventually upgrading to a 55 gallon aquarium is highly recommended.
10. Celestial Pearl Danio
Celestial Pearl Danios, sometimes called Galaxy Rasboras, are not as red as most other fish on this list, but their red fins explode in color and I felt they would be a great addition to this list. This species has a predominately blue/silver body, orange/yellow spots, and vibrant red fins. It is a gorgeous fish to keep in a heavily planted fish tank.
Celestial Pearl Danios enjoy staying in groups and will do best in groups of 6 or more individuals. Take caution against the number of males in the group, especially in smaller aquariums. If there are many males, with too few hiding places, the less dominant of the group will be picked on. Luckily, the Celestial Pearl Danio bicker amongst themselves and should not bother any other tank mates. This species will do great in well-planted 10-gallon fish tanks or larger. Take a look at the Celestial Pearl Danio Complete Care Guide for more information on this fish species.
Final Notes
There is an abundance of red-colored fish available for purchase. These are just a handful that stands out to me and that you can pick up for your aquarium. Take a look at 11 Blue Freshwater Fish for Your Aquarium if you’re looking for a different burst of color in your fish tank. Please let me know if you have a red-colored fish you think should have made a list.
