Our List of Green Tetras Ideas For Your Tank
In this list, we’ll see different types of tetras that have the color green. Some of them have a bright green color, while others have just a shade of green.
1. Green Neon Tetra
- Care level: Easy
- Size: Up to 1 inch
- Temperature range: 73 to 80 °F
- PH range: 5.5 to 6

The green neon tetra belongs to the same family of the regular neon tetras and the cardinal tetra. These fish live from 2 to 3 years, but they might live longer with the excellent care you’ll offer.
Their natural habitat is the basins of rivers like the Amazon, the Negro, and the Orinoco. They prefer slower water with trees and debris around.
All you’ll need to imitate their natural habitat are; Sandy
Speaking of care, it’s relatively easy to look after your green tetra. You should get at least six fish together, so we recommended a 10 to 20-gallon tank. They require very soft water so you should also change about 25% of the water once a week. Use a test kit regularly as well.
Now let’s see their diet. Green neon tetras are omnivores. You’re good to go with standard flakes, as long as you crush them into tiny pieces. However, some aquarists might prefer adding bloodworms or mosquito larva, now and then.
If you want a variety in your tank, you can get other species with them, as long as they’re peaceful fish, with the same size or smaller. Any big or aggressive fish will just make your green tetra stressed.
2. Congo Tetra

- Temperature range: 75 to 81 °F
- PH range: 6 to 6.5
- Social Behavior: Peaceful. Don’t put with aggressive species
- Tank size: A 30-gallon tank
Congo tetras are the biggest tetras on the list. That’s why we wouldn’t recommend a tank smaller than 30 gallons. They live from 3 to 5 years. They glow in all the colors of the rainbow, which gives a pleasant look to your aquarium.
You can tell from their name that they are found in the basin of the Congo river. They live in murky freshwater, with a

Congo tetras are omnivorous. They’ll eat whatever you offer them. Flakes are a good option, but you should opt for brine shrimp and bloodworms from time to time.
They live in groups, so a group of 6 would be ideal for your tank. You might add other tetras in the tank but stay away from any aggressive fish. Congo tetras get stressed quickly, and they’ll hide if there are bigger or feisty fish in the same aquarium.
3. Rainbow Tetra
- Care level: Intermediate
- Size: 1.18 to 1.57 inch
- Temperature range: 71.6 to 82.4 °F
- PH range: 6 to 7.2
- Social Behavior: Better kept in groups, from 8 to 10 fish
- Tank size: A 10-gallon tank
The colorful rainbow tetras live for 3 to 5 years. Their origins are in the basin of the Calima river in Western Columbia.
These fish need to live in an aquarium similar to their natural habitat. That’s why you’ll need to add sandy
They’re also omnivorous, so they have a similar diet as other tetras on the list; dried flakes and bloodworms.
Rainbow tetras are peaceful. However, adult males tend to be somehow territorial. To contain this, you can get at least eight fish of males and females. You might also add another schooling fishes if they’re of the same size or smaller.
4. Diamond Tetra
- Care level: Easy
- Size: 2.3 inches
- Temperature range: 75 to 82 °F
- PH range: 6 to 7
- Social Behavior: Better kept with a group of 5 or more.
- Tank size: 20 to 30-gallon tank
Diamond tetras are the last fish on our list, and also the most glowing ones. Diamond tetras come in a silvery-violet scale, with shades of green and gold. They live from 3 to 6 years.
Their natural habitat is shallow waters in lake Valencia. To offer a similar habitat, you’ll need leaves, sandy
A perfect diet for them would consist of dried flakes, bloodworms, and brine shrimps. They’re omnivorous. Don’t keep them hungry as they’ll start eating the plant used for decoration.
Keep in a group of 6 fish together to make them feel comfortable. However, they’re compatible with other species such as; zebrafish, Odessa barb, and rosy barb.
Their flashy colors will add a lovely shape to your aquarium, and you can easily take care of them even if you’re a beginner.
Do Tetras Die Easily?
Unfortunately yes. Taking care of your green tetras is not hard work. However, any minimal change in the water chemistry or tank conditions can harm your fish. They might be infected or catch a disease, and that’ll lead to their death.
You can tell if your fish is dying if it’s stressed, swimming in weird patterns, or simply can’t lift itself in the water.
What Type of Tetras Can’t Get Along With Green Tetras?
Most tetras are peaceful, and they can be kept in the same tank without any issue. However, beware of Serpae tetras and Buenos Aires Tetras. Why?
Serpae tetras can nip other fish if they’re kept in small groups while Buenos Aires tetras can get larger than the rest of tetras, which might scare them or make them stressed.
How Can I Tell If My Tetras Are Happy?
They won’t be laughing and smiling, but some signs can tell you when your tetras are happy, they’ll swim energetically, they won’t hide in any corners, and they’ll have a glowing skin.
Moreover, they’ll breathe as usual, and their eating habits won’t change.
My Final Thoughts
Fish are among the most peaceful pets to have. All you need to do is get an aquarium, decorate it, and let the green tetras illuminate it with their flashy colors and amusing palette.
Put the right amount of effort into raising your fish, and you’ll enjoy watching them grow and swim playfully around the tank.
