Origin:

The Platy is native to the East coast of Central America.

Up to 3 inches

Aquarium Size:

45 litres/10 gal

Preferred water conditions:

  • Temp: 20 – 27°C
  • pH: 7 – 8.5
  • Hardness: Hard

Diet:

Platy are omnivorous and will happily accept a wide range of aquarium foods. This can be supplemented with meaty treats such as blood worms and brine shrimp.

Behaviour:

Platy are a peaceful fish but are prolific breeders. Males may harass females in attempts to impress them with their colours, for this reason, it is best to keep 2 females to every male, to spread out the male’s attention.

An alternative is to keep only male fish, without females they will have no-one to harrass. However, be aware that adding any female livebearer, even of a different species (eg molly or swordtail) may attract the male’s attention.

Sexing:

The anal fin of a male will appear narrow and pointed. The females anal fin will be broad or wider.

Males are slender-bodied whilst females tend to be a little rounder.

Breeding:

Breeding Platy is extremely easy and they will breed constantly without encouragement.

Platy are livebearers which means they give birth to live fry.

Females will become larger and will develop a dark patch on their back end known as a gravid spot. This spot will become darker as their pregnancy progresses.

Parents and other fish are likely to eat the fry. A densely planted tank will provide lots of hiding places for them to hide and grow. Alternatively consider a separate fry tank.

Notes:

Platy are one of the most popular aquarium fish. They are very beginner-friendly as they are quite hardy and can be an interesting first breeding project.
