When the fry are around 3 weeks old, you can determine their genders in one rather unusual way: by overfeeding them. When the female guppy gets fat, her belly will round out while the rest of her body remains trim. In the male, the chest area will swell instead, leaving the rest of the guppy streamlined.
At what age do baby guppies get their color?
Typically, they will begin to get some color when they are between 1 week and 6 weeks old.
How often should guppies be fed?
Mature Guppies
Feed adult guppies once or twice a day. At least one meal should consist of live food. Unlike young fish, whose frequent meals support rapid development, adults function well with fewer meals.
What are the rarest guppies?
Rare Champions
Guppies from the snakeskin class produce some of the most rare offspring. Fish who carry the snakeskin genetic trait, and show a rosette pattern on the body, are exceptional. A solid blue tail snakeskin would be an example of a rare fish, a matching dorsal and tail color, is rarer still.
Will guppies overeat?
If you have guppy fish (Poecilia reticulata) in your aquarium, never overfeed them. Inordinate amounts of food can often be detrimental to the health and well-being of these freshwater fish, so take note.
