Najas guadalupensis, commonly known as Guppy Grass, is a fast-growing and extremely practical floating or mid-water stem plant producing dense masses of very fine, narrow, bright green leaves. Its exceptional utility as a refuge and spawning habitat for fish fry, shrimp, and invertebrates has made it one of the most popular functional plants in breeding, shrimp, and community aquariums worldwide.
It is extremely easy and undemanding, growing rapidly without CO2 under low to medium light across a very wide range of water conditions including both hard and soft water. It can be used floating, submerged in mid-water, or lightly anchored to the substrate — it adapts readily to any position. Fast-growing and requiring periodic thinning to prevent it overcrowding the tank.
Supplied as a Tropica 1-2-GROW! tissue culture cup, this plant arrives completely free from snails, pest algae, and pesticide residue. Rinse the gel and simply float or submerge the plant as desired. Suits aquariums from 20 litres upward — a fast-growing, versatile functional plant that is fully shrimp safe and invaluable in breeding and shrimp set-ups.
