The Pintail Platy, known in English as Platy Pintail, is a selective breeding form of the common Platy, not found in the wild. A distinctive feature of this fish is the unusual structure of its caudal fin, the central rays of which are elongated, resembling a small brush. Since this is an inherited trait, it can be passed on to hybrid offspring resulting from crosses with other varieties of Platies. Consequently, fish of the most diverse colors are offered under the same name.

Frequently asked questions

The essentials: size, tank volume, water parameters and care

How big does Pintail Platy get?

An adult reaches 5–7 cm in length. Plan the tank around the maximum size: the fish quickly outgrows a cramped setup.

What size aquarium does Pintail Platy need?

The minimum recommended volume is 60 L. A smaller tank speeds up nitrate build-up and raises stress levels.

What water parameters does Pintail Platy need?

Temperature 20–28 °C, pH 7–8.2, hardness 9–20 dGH. Stability matters more than exact values: sudden swings are harder on the fish than a small deviation from the ideal.

How long does Pintail Platy live?

Around 4 years when kept properly. Lifespan depends directly on tank volume, water quality and a varied diet.

Is Pintail Platy aggressive?

Temperament: peaceful (regular). Keep this in mind when choosing tank mates.

How many Pintail Platy should be kept together?

Recommended setup: mixed (solitary / pair / group). Ignoring this is a common cause of stress and disease.

What does Pintail Platy eat?

Diet type: any (universal). Feed small portions that are finished within a couple of minutes — overfeeding does more harm than underfeeding.

What is the scientific name of Pintail Platy?
