Bought some duckweed yesterday & put it in my tank. The zebra danio's immediately started feasting on it. A couple hours later my Buenos Aires Tetras joined in. Woke up this morning to find no duckweed in my tank. Anybody know of a way to prevent this?
The great thing about floating plants is that the lighting is *almost* immaterial, because they're so close to the surface anyways, that they recieve the full blast of light before it can be scattered when passing into the water.
