Physical Characteristics of a Boxy Guppy

The Boxy Guppy, also known as the Triangle Tail Guppy, is a unique and sought-after breed among guppy enthusiasts. This fascinating fish boasts several distinctive physical characteristics that set it apart from other guppy varieties. In this blog post, we will explore the physical characteristics of a Boxy Guppy in detail.

Body Shape:

The most distinguishing feature of a Boxy Guppy is its boxy or triangular-shaped body. Unlike the common round-bodied guppies, this variety has a more angular and elongated body shape. The square or triangular shape is most prominent when viewed from the top.


Boxy Guppies are not particularly large fish. They typically grow to an average size of 2 to 2.5 inches (5 to 6.3 centimeters) in length. However, some individuals may reach up to 3 inches (7.6 centimeters) in length, depending on their genetics and environmental conditions.


One of the striking physical features of a Boxy Guppy is its elaborate finnage. The males, in particular, possess long and flowing fins that enhance their overall beauty. The dorsal fin is large and can be triangular or fan-shaped, while the caudal fin is often elongated and resembles a triangle. The anal and ventral fins also tend to be long and flowing.


Boxy Guppies come in a variety of colors and patterns. The base coloration can range from solid colors like red, blue, and black to more intricate combinations of multiple colors. The fins often display vibrant and contrasting hues, further enhancing the fish's visual appeal. It is important to note that the intensity of coloration can vary considerably between individuals and is influenced by factors such as genetics, diet, and water conditions.

Body Pattern:

Aside from color, Boxy Guppies can exhibit various body patterns. Some individuals may have a solid color throughout their body, while others may display patterns such as stripes, spots, or even intricate mosaic-like designs. These patterns can be present on the body, fins, or a combination of both.

Swim Bladder:

One unique characteristic of the Boxy Guppy is its modified swim bladder. The swim bladder is an organ that helps fish control their buoyancy. In the case of the Boxy Guppy, the swim bladder is situated closer to the anterior part of the body. This placement contributes to the fish's distinctively boxy shape.

Overall, the Boxy Guppy is a visually stunning fish with its boxy body shape, elaborate fins, vibrant colors, and intricate body patterns. Whether you are an experienced guppy breeder or a hobbyist looking to add a touch of elegance to your aquarium, the Boxy Guppy is a captivating addition that is sure to impress.
