How much water weed does a minnow eat in a day?

Minnows typically eat small amounts of plant material, including water weeds, as part of their diet. However, the exact quantity can vary depending on the species, size, and availability of food sources. On average, a minnow might consume a few grams of water weeds daily, but they primarily feed on small invertebrates and plankton. It's important to note that their diet can change based on environmental conditions and habitat.
