Azolla

Azolla is a tiny floating fern that forms a delicate carpet of overlapping scale-like fronds across the water's surface, blushing red under strong light. It's a fast, thirsty nutrient-sponge that shades the tank and offers cover for fry and shrimp, though it multiplies quickly enough to need regular thinning. A charming, low-effort floater.
