I'm about going nuts keeping my platys in plants! They eat the roots off of floaters and take bites from leaves of substrate plants. Thinking about actually introducing duck weed as it might keep up with demand. There are only 4 female platys, and I do include algae wafers in their diet. They are fat little girls and sending fry into the world regularly. I added some miniature water lettuce yesterday, and the roots are obviously shorter this morning. Other than a constant influx of new plants, and possibly duck weed, do any of you have any suggestions? I'm tired of loosing my nice planted plants to these hearty little munchers!
