<p>most loved tiny fish</p>
Neon Tetras are one of the most loved tiny fish in the world. They shine with bright blue and red colors that make every fish tank look more alive. Many people pick them because they are easy to keep and very calm.
Even though they are small they also need love and care like all pets. If you follow the right steps, they can live happy lives for many years. Owning Neon Tetras is not hard but there are some rules you must never forget.
Provide Enough Space
Neon Tetras may be small but they like to swim in groups. They are schooling fish which means they are happiest when they swim with others. You should never keep just one or two because they can get scared and sick. The best way is to keep at least six but more is always better.
The tank must also be big enough. A small bowl will not work because it will stress them. A tank of at least ten gallons is needed to give them freedom to move around. When they have space then they act playful and show their brightest colors.
The water in the tank is the home of your Neon Tetras so if the water is dirty then the fish will not survive. You must change a part of the water every week. This keeps the tank fresh and safe for them. A simple water filter can also help a lot.
The temperature of the water must also be right. Neon Tetras need warm water between 72 and 80 degrees Fahrenheit. If the water is too cold then they will become weak. If the water is too hot, they will get stressed. A small heater will make it easy to keep the tank warm enough.
Feed Them the Right Food
Food is another important rule for keeping Neon Tetras. They are not picky but they need a mix of different foods. Flakes, tiny pellets and even frozen food like brine shrimp are good for them. When you give them variety, they grow stronger and show better colors.
You must be very careful not to give too much food. These fish have very tiny stomachs. If extra food is left in the tank then it will rot and make the water dirty. The best way is to feed them only what they can finish in two minutes.
Neon Tetras love peace and calm. They do not like loud sounds, sudden shocks or rough fish around them. If they stay with aggressive fish, they will hide all the time and even stop eating. Good friends for them are guppies, mollies and peaceful bottom-dwellers.
Plants and decorations also make them feel at home. They like shadows, soft lights and green plants in the tank. A natural tank helps them glow brighter and reduces their stress. When they feel comfortable, you will see them swimming beautifully in groups.
Watch Their Health Closely
The last rule is to always keep an eye on their health as Neon Tetras are delicate and can fall sick if water or food is not right. You must check them every day to see if they are swimming well and if their colors are bright. If you see white spots, torn fins or if they stop eating, then something may be wrong.
Early care can save them from bigger problems. Clean water, right food and peace in the tank are the best medicines for them. A healthy Neon Tetra will always move happily with the group and shine like a gem in the water.
Owning Neon Tetras is fun and joyful if you follow these top five rules. They need space, clean water, good food, a calm tank and regular care. Even though they are tiny they will fill your home with color and peace. When you give them the right life in return they reward you with beauty every single day.
