Biofilm is a natural and highly nutritious food source for shrimp, and a simple method allows it to be produced in large quantities. Traditionally, leaves, water, and bacterial additives were placed in a bucket to cultivate biofilm, but adding one teaspoon of brown sugar to the mix greatly accelerates its growth. How it works: Use a 20L bucket of remineralized water (GH/KH+ for Neocaridina shrimp). Add banana leaves , a bacterial product (such as Bacter AE or dead shrimp powder), and 1 teaspoon of brown sugar . Provide aeration with an airstone. Leave the mixture for 2–3 days for optimal biofilm production, refreshing it weekly. The sugar serves as fuel for bacteria, producing a thick, slimy biofilm layer on the leaves—described as “like wallpaper paste.” Shrimp eagerly feed on these biofilm-covered leaves, resulting in rapid breeding and population growth in the tanks. It’s important to wa...
