Why would a 1 month old Betta male fish sit at the bottom of tank and is cleaned every week?

There are a few possible reasons why a 1-month-old Betta male fish might be sitting at the bottom of the tank.

* Water quality: Bettas are very sensitive to water quality, and even small changes in the pH, temperature, or ammonia levels can cause them to become stressed and lethargic. Make sure that your tank is cycled and that the water parameters are within the recommended range for Bettas.

* Temperature: Bettas are tropical fish and prefer warm water between 75 and 82 degrees Fahrenheit. If the water in your tank is too cold, your Betta may become lethargic and inactive.

* Stress: Bettas can become stressed by a variety of factors, including changes in their environment, new tank mates, or overcrowding. If your Betta is new to the tank, he may be feeling stressed and need some time to adjust. Make sure that the tank is in a quiet location and that there are no other aggressive fish in the tank.

* Disease: Bettas can also be susceptible to a variety of diseases, including bacterial infections, fungal infections, and parasites. If you notice any unusual symptoms, such as spots or lesions on the body, difficulty breathing, or loss of appetite, it's important to take your Betta to the vet.

If you've checked all of these factors and your Betta is still sitting at the bottom of the tank, it's important to take him to the vet for a diagnosis.

Here are some tips for keeping your Betta healthy and happy:

* Make sure that your tank is cycled and that the water parameters are within the recommended range for Bettas.

* Keep the water temperature between 75 and 82 degrees Fahrenheit.

* Avoid overcrowding the tank and make sure that there are no aggressive fish in the tank.

* Feed your Betta a diet of high-quality food and offer him a variety of foods, such as live food, freeze-dried food, and pellets.

* Watch for signs of stress or disease and take your Betta to the vet if you notice anything unusual.
