What To Do If Your Betta Is Chasing Cardinal Tetras?
Betta fish have been in the aquarium hobby for decades, yet many owners of these fishes often have no idea what to do if their Betta is chasing Cardinal Tetras.
This is because most Betta owners are often unaware that there are a few different types of betta fish, some of which may be aggressive towards other species that swim in their tank.
To stop betta chasing, you can separate your tetras for a while and add some of the decoration like rocks and other things to distract other fish.
You can also separate your fish into two other tanks for a while to make them comfortable with each other.

Can Betta Fish Eat Cardinal Tetras Food?
Betta fish are known to be picky eaters. Therefore, it is generally recommended that you provide them with live or frozen foods. Live food options are bloodworms, daphnia, mosquito larvae, brine shrimp, and worms. Frozen foods include bloodworms and krill.
Cardinal tetras are omnivores, meaning they will eat both plant and animal-based food items in the wild. Therefore, they will eat boiled or frozen peas, garlic, lettuce, other greens, and algae.
You can also feed them live food options such as bloodworms, daphnia, and mosquito larvae once in a while. However, you should note that too much plant-based food will cause the cardinal tetras to develop digestive problems.
Also, note that tetras require more meaty food items than other fish. This is why you should refrain from feeding them plant-based food regularly.
Instead, it is generally recommended that you provide them with fish flakes as their main diet since they are high in protein.
Nonetheless, they also need supplements of vegetable-based foods now and then to ensure good health.
What Size Tank Is Best To Betta With Cardinal Tetras?
As you know, the cardinal tetras are the schooling fish, and you would need a minimum of four to six in your tank with bettas.
Thus, choosing the right sized tank to accommodate both fishes becomes essential. That is why you can buy a minimum of 20 gallons water tank, which would be enough for them to live.
But if you do not have any budget problems, go for the 30 gallons to make it more comfortable for the fishes to hide and have a private place to relax and swim.
