Guppy Grass (Najas guadalupensis)

Guppy Grass (Najas guadalupensis)

Guppy Grass is a fast-growing, fine-leaved aquatic plant known for its dense, bushy appearance. Its delicate stems create a natural-looking thicket that provides excellent cover for shrimp, fry, and small fish.

It is a versatile plant that can be planted into the substrate or simply left floating. As it grows quickly and branches freely, regular trimming helps maintain a compact and attractive shape.

Aquarium Use

Guppy Grass is particularly useful in breeding and shrimp aquariums, where its dense foliage offers shelter for fry and small aquatic life. It can also be used as a temporary or fast-growing filler plant while an aquascape develops.

Care

Provide adequate light and nutrients for healthy growth. Because it grows rapidly, occasional trimming is recommended to prevent it from becoming overly dense or shading other plants. Cut stems can be replanted or left floating to produce new growth.
