Lifespan
On average, Lemon Tetras have a lifespan of 3-5 years in captivity. However, with proper care, they can live up to 7 years.
Appearance
The Lemon Tetra has a bright yellow body with a silver iridescent stripe that runs from its head to its tail.
They have a small black spot on their dorsal fin, which distinguishes them from other tetra species. Males are generally more colorful and have longer fins than females.
Size
Lemon Tetras are small fish, growing up to 1.5 inches in length. They are ideal for small aquariums and can be kept in groups of 6 or more.
Growth Rate
Lemon Tetras have a moderate growth rate and can reach their full size within a year.

Personal Anecdote: I have kept Lemon Tetras in my aquarium for several years and have found them to be a joy to watch. They are always active and playful, and their bright yellow color adds a beautiful pop of color to my tank.
Tank Setup
When it comes to setting up a tank for Lemon Tetras, there are a few key factors to consider to ensure that your fish thrive in their new environment. Here are some important things to keep in mind:
Tank Size
The minimum tank size for a small school of Lemon Tetras is 20 gallons. However, if you want to keep a larger group, you’ll need a bigger tank.
A 40-gallon tank is a good size for a school of 10-12 fish. Remember, the more space your fish have, the happier and healthier they will be.
Lighting
Lemon Tetras don’t require any special lighting requirements. A standard aquarium light will do just fine. However, it’s important to ensure that the light doesn’t overheat the water, as this can be harmful to your fish.
Filtration & Aeration
Good filtration and aeration are crucial for a healthy tank environment.
A hang-on-back filter is a good option for a Lemon Tetra tank, as it provides good water circulation and filtration. Aeration can be provided by an air stone or a bubble wand, which will help to oxygenate the water.
Heater
Lemon Tetras require a water temperature of around 75-80°F. A good quality heater is essential to maintain a consistent temperature in the tank. Make sure to choose a heater that is appropriate for the size of your tank.
Substrate
A fine gravel or sand substrate is ideal for a Lemon Tetra tank. This will allow the fish to forage for food and create a natural-looking environment. Avoid using sharp or jagged gravel, as this can damage your fish.
Decoration
Adding some decorations to your tank can help to create a natural-looking environment for your Lemon Tetras. Driftwood, rocks, and caves are all good options. Just make sure to avoid any decorations with sharp edges that could harm your fish.
Plants
Lemon Tetras enjoy having plenty of plants in their tank. Live plants not only provide a natural look but also help to oxygenate the water and provide hiding places for your fish.
Some good plant options for a Lemon Tetra tank include Java Moss, Anubias, and Amazon Sword.
I’ve found that setting up a tank for Lemon Tetras can be a fun and rewarding experience. Just make sure to keep these key factors in mind to ensure that your fish are happy and healthy.
Water Quality
Water Temperature
Maintaining the right water temperature is crucial for the health of your Lemon Tetras. The ideal water temperature for these fish is between 72-82°F.
Keeping the water temperature within this range will ensure that your fish are comfortable and thrive in their environment.
Water pH
The pH level of your tank water is also important for the health of your Lemon Tetras. The ideal pH range for these fish is between 6.0-7.5.
Maintaining the correct pH level will help your fish stay healthy and prevent stress-related illnesses.
Water Hardness
Lemon Tetras prefer soft to moderately hard water. The ideal water hardness range for these fish is between 4-12 dGH.
If your water is too hard, consider using a water softener or adding driftwood to the tank to help lower the hardness level.
Water Changes
Regular water changes are essential for maintaining good water quality in your tank. You should aim to change 25% of the water in your tank every two weeks. This will help remove any harmful toxins and keep the water clean and clear.
It’s important to note that sudden changes in water temperature, pH, or hardness can be stressful for your fish and can even be fatal. When making any changes to your tank water, do so gradually over a period of several days.
I once made the mistake of changing the water in my Lemon Tetra tank too quickly, and it caused my fish to become stressed and sick.
Since then, I’ve learned the importance of making changes slowly and carefully to keep my fish healthy and happy.
Diet
What To Feed
When it comes to feeding your Lemon Tetra fish, you have a few options. They are omnivorous, meaning they eat both plant and animal matter.
You can feed them a combination of flakes, pellets, and frozen foods. It’s important to make sure the food is high-quality and specifically designed for tetras.
I recommend feeding them a variety of foods, including:
- High-quality flakes or pellets
- Frozen or live brine shrimp
- Frozen or live bloodworms
- Daphnia
Frequency
Lemon Tetras should be fed 2-3 times a day, but in small amounts. Overfeeding can cause health problems and pollute the water. A good rule of thumb is to only feed your fish what they can consume in 2-3 minutes.
Tips
Here are a few tips to keep in mind when feeding your Lemon Tetras:
- Don’t forget to vary their diet – this will ensure they get all the necessary nutrients.
- If you’re going to be away for a few days, consider using an automatic feeder.
- Avoid feeding them too much at once – this can cause digestive issues.
- Keep an eye on the water quality – overfeeding can cause ammonia and nitrate levels to rise, which can be harmful to your fish.
I’ve found that my Lemon Tetras are particularly fond of frozen bloodworms. Whenever I add them to the tank, the fish go crazy! It’s always fun to watch them dart around, trying to get their share of the food. Just remember to only give them a small amount at a time.
Tank Maintenance
Maintaining a clean and healthy environment for your Lemon Tetras is essential to their well-being. Here are a few tips to keep your tank in top condition:
- Regular water changes: You should aim to change 25% of your tank water every two weeks. This will help to remove any excess waste and debris that could harm your fish. Don’t forget to use a water conditioner to remove any harmful chemicals from your tap water.
- Vacuum the substrate: The substrate in your tank can harbor a lot of waste, so it’s important to vacuum it regularly. Use a siphon to remove any debris that has settled on the bottom of your tank.
- Clean the filter: Your filter is responsible for removing waste and debris from the water, so it’s important to keep it clean. Rinse the filter media in a bucket of tank water to remove any excess debris, and replace it every 4-6 weeks.
- Check the temperature: Lemon Tetras thrive in water that is between 72-82°F. Use a thermometer to check the temperature regularly and adjust your heater as necessary.
- Test your water: It’s important to test your water regularly to ensure that the pH, ammonia, and nitrate levels are within safe ranges. You can use a test kit to do this, and adjust your water chemistry as necessary.
Personally, I’ve found that following these maintenance tips has helped me keep my Lemon Tetras healthy and happy. By staying on top of tank maintenance, you can ensure that your fish have the best possible environment to thrive in.
Tank Mates
If you’re planning on keeping Lemon Tetras, it’s important to consider their tank mates carefully. Here are some things to keep in mind:
Compatible Fish Species
Lemon Tetras are generally peaceful fish that get along well with other peaceful community fish. Some good tank mates for Lemon Tetras include:
- Corydoras Catfish
- Dwarf Gourami
- Neon Tetras
- Harlequin Rasboras
- Cherry Barbs
Incompatible Fish Species
While Lemon Tetras are generally peaceful, they can become aggressive towards smaller fish. It’s best to avoid keeping them with fish that are too small or too slow-moving.
Some fish species that are not compatible with Lemon Tetras include:
- Shrimp
- Snails
- Guppies
- Bettas
How Many Lemon Tetras Should Be Together
Lemon Tetras are schooling fish, which means they should be kept in groups of at least 6-8 individuals. Keeping them in smaller groups can cause stress and aggression among the fish. It’s important to provide enough space in the tank for the entire school to swim comfortably.
Personally, I have had success keeping Lemon Tetras with Corydoras Catfish and Harlequin Rasboras. They all get along well and create a beautiful and peaceful community tank. Remember to always research and carefully consider the compatibility of any fish species before adding them to your tank.

Breeding
Breeding Lemon Tetras can be a fun and rewarding experience. In this section, we’ll cover everything you need to know to successfully breed these beautiful fish.
Breeding Setup
Before you start breeding, you’ll need to set up a breeding tank. This tank should be at least 10 gallons and have a sponge filter to provide gentle filtration. You’ll also need to provide plenty of hiding places for the fish, such as plants, rocks, and caves.
How To Breed
To breed Lemon Tetras, you’ll need to start by selecting a breeding pair. Look for a male and female that are healthy and active.
Once you’ve selected your pair, you’ll need to condition them by feeding them a high-quality diet of live or frozen foods.
To encourage breeding, you’ll need to raise the temperature of the tank to around 78°F and provide a spawning mop or breeding cone for the fish to lay their eggs on. The eggs will hatch in about 24-36 hours, and the fry will become free-swimming in about 5-7 days.
Care
After the eggs hatch, you’ll need to provide the fry with plenty of small, live foods such as infusoria and baby brine shrimp. You’ll also need to perform frequent water changes to keep the water clean and healthy for the fry.
As the fry grow, you can start feeding them larger foods such as crushed flakes and small pellets. Eventually, they will be large enough to join the main tank with the adult fish.
Personal Anecdote: When I first started breeding Lemon Tetras, I was nervous about the process. But with a little research and some trial and error, I was able to successfully breed and raise a healthy batch of fry. It was a rewarding experience that I’ll never forget.
