    In a 56-day feeding trial, the impact of dietary cinnamon supplementation on juvenile Heteroclarias (Clarias gariepinus ♀ × Heterobranchus bidorsalis ♂) was examined. Five experimental diets with varying levels of cinnamon powder (ranging from 0% to 2.0%) were formulated. The study found that cinnamon supplementation positively influenced the fish's growth, haematology, serum biochemistry, intestinal microbiota, and enzyme activities. The group fed with 1.5% cinnamon (DT4) showed the highest growth performance, haematological indices, antioxidant, and hindgut enzyme activities. Additionally, the cinnamon-fed groups exhibited a significant reduction in total cholesterol levels, except for the 0.5% cinnamon-fed group (DT2). Blood glucose, blood urea nitrogen, and creatinine levels also decreased significantly in the cinnamon-fed groups compared to the control. Cinnamon supplementation increased bacterial counts, but fungi counts showed diverse effects, with the most favourable diversity indices observed in the 1.5% cinnamon group (DT4). Amylase, cellulase, and trypsin activity in the cinnamon-fed group were significantly higher than in the control group. Notably, all cinnamon-fed groups' intestine, liver, and kidney microstructures remained well-preserved, without any signs of injury. This study demonstrates that cinnamon has the potential to enhance the growth and overall well-being of African catfish hybrids. The optimal outcomes were observed when cinnamon was supplemented at a level of 1.5%, which can have significant implications for improving aquaculture practices and fish health
