Check the water often to make sure it’s good for your fish. Use a test kit to watch the pH, ammonia, and nitrate levels.

Feed your Brass Tetras the right food to keep them healthy. Give them high-quality food, with some live or frozen treats sometimes. Feed them little bits a few times a day to stop overfeeding.

Watch your fish for any signs of trouble like stress or sickness. Look for changes in how they act, eat, or look. If something seems off, get help from a pro or a vet right away.

Look for peaceful fish that are about the same size and calm like Brass Tetras. Don’t choose fish that are aggressive or like to claim territories. These could scare or hurt your Brass Tetras. It’s smart to pick fish that hang out in different parts of the tank. This way, they won’t fight over who gets what space or food.

Here are some examples of compatible tank mates for Brass Tetras:

To get Brass Tetras to breed, you must create the perfect tank conditions. They like water that’s soft and a little acidic, with a pH of 6.0 to 7.0. Keep the water between 76-80°F (24-27°C). Also, use a gentle filtration system to mimic their natural home. This makes sure the water flow is just right.

5. Raising the Fry

At first, fry will eat their yolk sacs. When they begin swimming, start with infusoria or powdered fry food. As they grow, offer bigger foods like microworms and newly hatched brine shrimp. Keep the water clean and change it often for healthy growth.

By following these tips, you can enjoy the full life cycle of Brass Tetras. Breeding these stunning freshwater fish is an adventure that can bring a lot of joy.

Clean water is essential for their health. Change the water regularly and use proper filters. This keeps the water quality high and avoids harmful toxins.

Creating a suitable tank environment is also important. Brass Tetras do best when their tank mimics their natural habitat. Make sure temperature, pH, and water hardness are just right. A stable tank helps keep them healthy.

Sometimes, despite your efforts, Brass Tetras might get sick. Act quickly if you see any disease signs. Moving sick fish to a quarantine tank stops diseases from spreading. Seeking advice from a vet or expert can be very helpful.
