Stress in the environment

Betta fish get stressed for many reasons. If your fish is not eating it can be an indicator that it is going through a phase of stress and this could be due to environment where your aquarium is located. If you are stressed, you will not feel like eating.

For example, a new tank, however big and cute it may be, will cause your betta anxiety, simply because it is an unfamiliar space. Give him time to get used to it. Fish rarely get sick unless they are under stress. So if you can reduce stress as much as possible, it will be the best option. That is, try not to constantly change the aquarium, choose one that is suitable for your fish, from day one.

It also happens that even though it is inside the tank, it still gets stress from movement in its environment - your house. A good solution is to bring a bit of darkness and calm to the aquarium. Cover it with a blanket so that the betta fish does not have to witness and attract all the movement that happens outside your home. Never hit the tank glass and teach the children to come to your house not to. The darkness will help you to adapt faster to your own environment. However, do not leave it in the dark all the time, most fish feed during the day and need light to be more active and therefore want to eat.

Can't fit so much food

A betta fish's stomach is the size of your eyeball ... very small. It is understandable that he does not eat much food and that, therefore, he does not eat as much as we can believe. So think that it will be enough to place a very small amount of food to feed your fish and that, many times, it will eat when you are not precisely observing it. Do not overfeed a betta fish, they have very common digestion problems that later translate into other diseases. Remember that to prevent your betta fish from stopping eating the formula is: little food but of good quality.

Aquarium conditions

If you still wonder why doesn't your betta fish eat, You should know that bettas are cold-blooded fish whose metabolism is directly related to the temperature of the water where they live. They require that it be stable between 24 ° C and 26 ° C. As the water is somewhat warmer, they metabolize their food faster, needing to eat more to maintain their own body temperature and energy. Despite being cold-blooded, when bettas are kept in colder water, their metabolism slows down and the need to eat will be less. Also, make sure the water parameters are in order: reasonable nitrates and very low ammonia and nitrite. To do this, consult our article in which we explain the basic care of betta fish.

Expression of any disease

Last but not least, you should rule out the possible presence of any disease in the body of the betta fish, since the lack of hunger is one of the most common symptoms. If you have tried to correct the above reasons and still don't know why your betta fish is not eating, you should pay attention to a general picture of alternating symptoms such as: lethargy and heaviness, loss of color, fins sticking instead of open, bloating in its stomach , torn and bloody fins, parasites and fungi. If some of these symptoms occur, the best is go urgently to the vet. You may be endangering not only the health of your fish, but also its own life.
