The behavior of aquarium fish is fairly easy to predict, but some individuals can behave downright strangely.
Like most living creatures, stress can lead to illness and problems in the home.
Therefore, if they huddle in a corner and react weakly to the influx of food, then they may be afraid of something.
It's better to solve this problem in advance.
It happens that a group of fish enters the breeding season and after breaking up into pairs, the remaining species remain on the sidelines.
They may begin to experience a lot of stress because of this, which leads to them retreating into a corner.
Therefore, it is better to move the pair separately so that the other fish feel freer. Diseases, parasites and unsuitable living conditions can also be the cause.
