Tank Size
A minimum of 45 litres (10 gallons) is recommended to provide ample space for both species to thrive. Neon Tetras are schooling fish and prefer to be in groups of six or more, requiring additional space to swim freely.
While often solitary, betta fish also benefit from space to establish their territory without feeling threatened. Larger tanks can accommodate bigger schools and more intricate setups.
Aquarium Setup
Setting up an aquarium for Neon Tetras and Betta Fish requires attention to detail. Both species thrive in warm water, ranging from 21° C -to 26.6° C (75° F to 80° F), so you’ll need a reliable heater.
Filtration is equally important. A gentle filter that does not create strong currents is ideal, as Betta Fish are not strong swimmers.
The pH level should be maintained between 6.5 and 7.5, with regular water testing to ensure the environment remains stable.
Aquarium Cycling & Maintenance
Before introducing any fish, the tank must undergo a cycling process to establish beneficial bacteria. This process typically takes 4-6 weeks and is critical for converting harmful ammonia and nitrites into less toxic nitrates.
Regular maintenance, including partial water changes and filter cleaning, will keep the tank healthy and prevent the buildup of waste products.
Aquascaping the Tank
Aquascaping, the art of arranging aquatic plants, rocks, and substrates, can greatly enhance the living conditions for both Neon Tetras and Betta Fish.
Neon Tetras appreciate densely planted areas, while Betta Fish benefit from broad-leafed plants and floating vegetation to rest on.
You can also add driftwood to provide hiding places for the fish.
Aquarium Plants
Live plants not only add aesthetic value but also contribute to the tank’s ecosystem by producing oxygen and absorbing nitrates.
Hardy plants like Java Fern, Anubias, and various mosses are excellent choices as they can tolerate the conditions preferred by both fish species.
Diet and Feeding
Neon Tetras and Betta Fish have different dietary needs. Neon Tetras are omnivores and do well with a diet of high-quality flake food, brine shrimp, and daphnia.
Betta Fish are carnivorous and require protein-rich foods like betta pellets, bloodworms, and occasionally live food.
Care should be taken to feed appropriate amounts to avoid overfeeding and potential water quality issues.
Feed Neon Tetras twice a day. Offer them what they can eat within approximately three minutes. For Betta Fish, feed them a pinch of food twice a day. Offer a variety of food to keep them healthy.
Health Problems & Disease
Both species are susceptible to common fish ailments such as fin rot, ich, and fungal infections.
Maintaining clean water, a balanced diet and monitoring for signs of stress or illness can prevent most health problems.
Quarantining new fish before adding them to the main tank can also reduce the risk of introducing diseases.
Breeding
Breeding Neon Tetras and Betta Fish in the same tank is not recommended due to differing breeding behaviours and requirements.
Betta Fish are bubble nest builders and can become aggressive during breeding, posing a risk to the peaceful Neon Tetras.
If you’re planning on breeding, separate breeding tanks with controlled conditions are necessary for each species.
Frequently Asked Questions
What are the signs of stress in these fish?
Signs include clamped fins, hiding, lack of appetite, or erratic swimming. Several factors can cause stress, such as a small tank, overcrowding, poor water quality, and aggressive tank mates. Ensure that the fish live in optimal conditions to prevent stress and diseases.
Can I add other fish species to a tank with Neon Tetras and Betta Fish?
It’s possible, but research compatible species that won’t trigger the Betta’s aggression or outcompete the Neon Tetras for food and space.
How many Neon Tetras should I keep in the tank?
Neon Tetras live in groups. It’s best to keep six at a time.
How many Betta Fish can I keep in the tank?
Keep only one Betta Fish in the tank as they can be aggressive to their species, especially with males.
