A Betta fish may develop a bloated belly due to overfeeding with nutrient-dense foods or a lack of fiber in its diet. Substandard water quality, bacterial infections, or internal parasites may also contribute to bloat in fish. All of these factors may lead to an expansion of the abdomen in fish and a belly that looks extremely swollen.
