Why is my Betta fish not eating?
We have prepared a list of nine most common issues connected to problems that cause your Betta fish to stop eating.
Picky pet fish
Some Bettas are very picky when it comes to food. As carnivores in their natural habitat, they eat almost everything that moves. Being introduced to a new home- the tank a Betta needs to adapt first and then understand the new diet which is a pellet in most cases. Give it some time.
Perhaps the water is too cold. Bettas like their water warm and they need special water parameters to be healthy. The water should be between 76 and 82 degrees. If the water isn’t warm enough their metabolism slows down and they lose appetite. They avoid eating and start laying at the bottom. That reflects on the issue of food. Always check the thermometer and if it shows that the water is within ideal limits double check it. They are cheap and easy to break.
If the quality of the water changes that can affect your Betta pet. Dirty water or keeping a lot of waste at the bottom from dissolved food can produce toxic chemicals such as ammonia that can cause serious health problems.
Avoid overfeeding and keep your filter running. Also, you should do the cleaning- scooping out bottom waste and you need to perform water change once in a while.
Performing all this you will avoid many conditions.
If your fish is stressed many problems can arise. Stress is caused by many factors. It can be connected to bad water parameters, tank mates, light, food, not having enough space, loneliness etc.
By observing you can notice what is wrong and change for the better. Check water for the best parameters possible and provide them to your pet. Introduce a tank mate, another fish or a female. Change light or move the tank to a better place. If a tank is too small have a bigger one. Provide a variety of food because Bettas know to be picky.
When you eliminate all listed you will no longer have a pet that doesn’t eat.
In some cases, Bettas are sick. By observing you will see the change and act accordingly. Illnesses such as bacterial, fungal or parasitic can show up. Depending on the kind you should start treatment. The best first step is to check water parameters first. Then take one step at a time searching for symptoms and recommended treatment. A lot of things you can do by yourself but if that is not the case try looking for professional help.
Sometimes your Betta isn’t hungry. In general, Bettas have a small stomach the size of their eyeball. It is very easy to fill in a space that small. If you give your Betta too much food you are overfeeding it. Overfeeding is bad for two reasons. First, your Betta will stop eating and secondly a lot of food finishes at the bottom of the tank turning into waste. Observe your fish every time you feed it and you will understand how much is enough per meal.
Keeping a bubble nest
Male Bettas are known for great guardians. In some cases, they exaggerate by stopping eating. If your Betta doesn’t eat because it keeps the bubble nest all the time, simply remove the bubble nest or introduce a female to mate with.
If the level of ammonia rises it will mate your fish into a lethargic state and suppress appetite.
You need to change one-third of the water and add an ammonia detoxifier.
This poisoning causes the same symptoms with Bettas as ammonia poisoning and that is lethargy and loss of appetite. The fish stays at the bottom. You have to react quickly by changing fifty per cent of the tank water. It can cause other problems too so it is better if you call professional help.
