Fish keepers use synthetic solutions to eliminate fungi by adding drops to the water, but several studies have shown that such chemicals are harmful to fish. This study aimed to assess the phytochemicals and antifungal activity of Tropical Almond (Terminalia catappa) leaf extract to manage fish fungal infection by eliminating external parasites. The research utilized 54 goldfish (Carassius auratus) divided into three groups (A, B, and C), with three replicates per dosage. Results showed that the Tropical Almond (Terminalia catappa) leaf extract used in this study contains alkaloids, tannins, and saponins. Treatments with Tropical Almond (Terminalia catappa) leaf extract in varying doses showed effectiveness in treating fish fungus infections. The highest concentration (12 mg) showed a greater effect. There was a statistically significant difference between the experiments and the control group (p value <0.05). But, results among the experimental groups showed no significant difference. The findings of this study suggest that this plant extract may be useful for treating fungal infections. However, to validate and further develop the findings of fungal inhibition, further research on antifungal activity tests is necessary. http://pubs.sciepub.com/ajzr/8/1/1/ajzr-8-1-1.pdf antifungal activity fungal infection goldfish (Carassius auratus) tropical almond (Terminalia catappa) leaf extract
