Goldmolly

Beschreibung

The Goldmolly is a popular aquarium fish, primarily a cultivated color morph or hybrid derived from species within the genus Poecilia, most commonly Poecilia latipinna (Sailfin Molly) and Poecilia sphenops (Shortfin Molly). These fish are livebearers, meaning they give birth to live young rather than laying eggs. They are known for their robust nature and adaptability, making them a favorite among aquarists. Wild forms typically exhibit more subdued coloration, while captive breeding has led to a vast array of colors and fin shapes, with 'Goldmolly' specifically referring to a golden-yellow coloration.

Besondere Merkmale

Livebearer (gives birth to live young), Sexual dimorphism: Males are generally smaller, more slender, and possess a modified anal fin called a gonopodium for reproduction. Females are larger and rounder., Varied fin shapes due to selective breeding (e.g., lyretail, balloon body forms, though these can lead to health issues).

Rückenflosse

Single dorsal fin, often large and sail-like in P. latipinna and its hybrids, smaller and more rounded in P. sphenops. Can have up to 13-14 rays in P. latipinna.

Schwanzflosse

Rounded to slightly emarginate caudal fin.

Brustflosse

Paired pectoral fins, typically clear or slightly colored.

Auffällige Flossen

Anal fin of males is modified into a gonopodium for internal fertilization.

Bestimmungstipps

Lebensraum

Wassertyp

brackish

Tiefe

Shallow waters, typically less than 1-2 meters.

Umgebung

Coastal freshwaters, brackish estuaries, salt marshes, and even hypersaline lagoons. They prefer slow-moving or still waters with dense vegetation for cover and feeding. Can tolerate a wide range of salinities.

Geografische Verbreitung

Native to the southeastern United States (P. latipinna, from North Carolina to Veracruz, Mexico) and Central America (P. sphenops, from Mexico to Colombia). Introduced populations exist worldwide due to their popularity as aquarium fish.

Aquarieninformationen

• Pflegeaufwand: beginner
• Temperament: peaceful
• Ernährung: omnivore
• Mindestbeckengröße: 30 gallons (for a small group)
• Temperatur: 22-28°C (72-82°F)
• pH-Wert: 7.0-8.5
• Härte: 10-25 dGH
• Verträglichkeit: Generally compatible with other peaceful, similarly sized community fish. Avoid fin-nippers or overly aggressive species.
• Besondere Anforderungen: Mollies appreciate well-planted tanks with open swimming areas. They benefit from slightly brackish water conditions (1-2 teaspoons of aquarium salt per gallon) which can help prevent diseases, though they can thrive in pure freshwater. A varied diet is crucial for their health and vibrant coloration.
