Grass
Variety
A grass guppy is recognized by fine speckling or seed-like dots, most often across the tail and dorsal fin. The pattern can appear in blue grass, red grass, yellow grass, and other color directions, with the best fish showing a dense but readable scatter rather than muddy blotches. It is a pattern strain, so body color and tail shape may vary between breeding lines.
Grass guppies reward patient selection because the pattern can thin out, merge, or become uneven in later generations. Breeders usually grow out many males before choosing those with clean dotting and balanced fins. In a display tank, the fine pattern looks best against plants and dark backgrounds, but ordinary livebearer care still comes first: stable water, regular feeding, and enough room to separate breeding groups when the line matters.
