Constipation is a condition of the digestive system where an animal experiences hard feces that are difficult to eliminate; it may be extremely painful, and in severe cases lead to symptoms of bowel obstruction and death.
In fish several species are more prone to this problem than others. Mainly this disease is due to our inability to feed the animal the correct type of food for its dietary requirements.
Typically the Gourami group tend to suffer from this as in the wild they feed mainly on insects and so it is difficult to feed them the correct amnount of fibre in their diet.
