Guppy males are usually 1.5-3.5 cm (1.6-1.4 in) long, while the female is about 3-6 cm (1.2-2.4 in) long. Likewise, the average body weight for a male is 0.07 ± 0.1 g, while females weigh 0.13 ± 0.1 g. Lastly, the mean height clocks in at 9mm.
Guppies can be born with a bent spine, develop it suddenly or progressively as they reach adulthood. It’s characterized by a curvature in the spine that looks like the letter S. Guppy bent spine is caused either by scoliosis or fish tuberculosis, both of which are untreatable.
