Platy

Undemanding livebearers in nearly every color. Like guppies, they breed freely; keep groups with both sexes and plants for fry cover.

• Minimum footprint: 10 gallons; a 15+ gallon tank gives real swimming room.
• Preferred swimming zone: middle of the water column.
• Social — keep a group of at least 3.
• Care level: easy.

• Temperature: 68–79°F
• pH: 7–8.2
• Hardness: 10–25 dGH (Hard)

Stable parameters matter more than perfect ones — aim for consistency before chasing an exact number.

An omnivore — offer a staple flake or pellet plus regular frozen or live foods (daphnia, bloodworm, brine shrimp) and some vegetable matter for balance.

A further 1 species pair with Platy as conditional — workable with the right tank and precautions.

Standard tanks at or above the recommended 15 gallons:

• 15 gallon 24 × 12 × 12″
• 20 gallon High 24 × 12 × 16″
• 20 gallon Long 30 × 12 × 12″
• All tank sizes

• Start from a 10 gallon minimum and plan the full group size (3+) before you buy.
• Activity level is moderate, which affects how much of the tank it uses and how much it adds to the bioload.
• Zoning matters: this species lives mostly in the middle zone, so choose tank mates that occupy other levels.

Compatibility depends on tank size, water chemistry, temperament, and adult size. Run a full check against any species in our database.
