Step 1: Putting the food in the tank

Remember to keep track of how much food you’re putting into the tank, as this will help you not add too much food. 

Step 2: Watch the neon tetras eat and pour in as they finish. 

It is always good to keep an eye on the Neon Tetras eating the food when it is being given to them. Once you start pouring in the food, they will start eating it. You can also pour in more food as they go on eating. You need to make sure that all your Neon Tetras are getting the food, are eating well, and that no one is being left out. This is crucial because the Neon Tetra is mid to top-level schooling fish. If the food falls to the bottom of the tank, the Tetras will find it impossible to eat it. This will create a leftover food problem which can make the tank dirty. It is always better to keep feeding them till they stop eating. 

Step 3: Feeding your Neon Tetras at night 

Feeding your Neon Tetras at night is extremely important. Just like we need food at night to survive, they too need daily feeding at night to stay healthy. At night, all you have to do is follow the similar feeding pattern mentioned above. Ensure that you are not overfeeding your Tetras.

However, if your fish tank’s circumstances are suitable for Neon Tetras, they can live for up to three weeks. 

The most essential thing to remember is that as long as your fish tank’s water quality is acceptable, your Neon Tetras will have a greater chance of surviving your absence. As a result, if at all feasible, execute a 50-70 percent water change just before you depart. Alternatively, you can clean the filtration system a few days before you leave, allowing the water to rebuild the good bacteria in the fish tank slowly.

Furthermore, on occasions that you are not at home, your Neon Tetras may depend on living plants as their primary food source. As a result, ensuring that your fish tank is well-stocked with live plants ought to be a significant priority!

If you are still anxious about the well-being of your Neon Tetras while you are away, you can invest in an automatic feeder or weekend feeders which will feed your fish on the days you are not at home.
