Betta fish are already famous for their remarkable, vivid colors, but recent research suggests that supplementing their diet with mushroom powder may intensify their natural coloration and improve their overall health.

A study published in the Journal of Applied Aquaculture examined 68 male Blue Veiltail Betta fish divided into three groups. One group was fed a standard control diet, while the other two were supplemented with either pearl oyster mushroom powder or pink oyster mushroom powder. After 60 days, the fish were evaluated for changes in their health or appearance.

Researchers found that none of the groups demonstrated a significant improvement in growth metrics. However, the fish treated with mushroom powder saw improved coloration, which was linked to the presence of melanin in oyster mushrooms. Furthermore, the treated fish were found to have improved immune response and reduced inflammation, likely due to the compounds found in oyster mushrooms, including beta-glucans and phenolic compounds. 

The researchers suggest that the use of mushroom powder as a dietary supplement could potentially be used for other ornamental fish species. However, more research will be needed to better understand the digestibility and nutritional benefits of mushroom powders for improving the appeal and well-being of aquarium fish (1).
