Molly Balloon - Platinum Lyretail

Platinum Lyretail Balloon Molly (Poecilia sphenops)

The Platinum Lyretail Balloon Molly is a selectively bred variety of Poecilia sphenops, prized for its stunning metallic silver coloration, elegant lyre-shaped tail, and distinctive rounded body form. This livebearing fish is popular among aquarists for its peaceful temperament, lively swimming behaviour, and shimmering appearance that adds brightness to any aquarium.

The “balloon” body shape results from a genetic modification that shortens the spine, giving the fish its compact, arched profile.

Aquarium Setup for Platinum Lyretail Balloon Molly

Filtration

Use a gentle yet efficient internal or hang-on-back filter. Mollies produce moderate waste, so effective biological and mechanical filtration is important.

• Keep ammonia and nitrite at 0 ppm

• Maintain nitrates below 30 ppm

Plants

Live plants such as Java Fern, Anubias, Vallisneria, and Hornwort work well.
Plants provide shade, improve water quality, and offer hiding places for fry.

Lighting

Moderate lighting is ideal to highlight their reflective platinum coloration and support healthy plant growth.
Avoid excessively bright lighting that may stress the fish or promote algae growth.

Heating

Maintain a steady temperature between 24–27 °C.
Use a reliable heater with a thermostat and prevent sudden temperature changes.

Substrate

Choose fine gravel or sand as the substrate.
The smooth texture prevents fin damage and creates a natural-looking environment.

Decorations

Add smooth rocks, driftwood, and live plants to create a balanced and visually appealing aquascape.
Avoid sharp decorations that may injure their fins or delicate body shape.
Provide open swimming areas, particularly in the middle and upper regions of the tank.
