Assorted Mollies

Overview

• Common Species: Poecilia sphenops (short-finned molly), Poecilia latipinna (sailfin molly), Poecilia velifera (giant sailfin molly).
• Varieties: These fish come in a range of colors and patterns, including black, dalmatian, gold dust, and balloon molly.

Size

• Standard Mollies: Typically reach 3-4 inches in length.
• Jumbo Mollies: Can grow up to 5-6 inches, though sizes vary depending on the specific variety and environmental conditions.

Lifespan

• On average, mollies live for 3-5 years, but in optimal conditions, Jumbo Mollies can live up to 6 years.

Behavior

• Mollies are peaceful, social fish that thrive in community tanks.
• They are livebearers, meaning they give birth to free-swimming fry rather than laying eggs.

Habitat & Tank Setup

• Tank Size: Jumbo mollies need a tank of at least 30 gallons due to their larger size.
• Water Parameters: Mollies prefer slightly brackish water with a pH of 7.5-8.5 and a temperature range of 72°F to 82°F (22-28°C).
• Aquarium Setup: They appreciate densely planted tanks with plenty of swimming space.

Diet

• Mollies are omnivores. They thrive on a varied diet, including algae, high-quality flake food, brine shrimp, and vegetables like blanched zucchini or spinach.
• They also enjoy snacking on algae growing in the aquarium.

Breeding

• Mollies are prolific breeders. A single female can give birth to 20-100 fry every 30-45 days.
• If you're breeding Jumbo mollies, separate the adults after the fry are born, as they may eat their young.

Tank Mates

• Mollies are compatible with peaceful community fish like tetras, guppies, platies, and some smaller catfish.
• They also pair well with other livebearers but avoid aggressive or fin-nipping species.

Water Tolerance

• Mollies are known for their adaptability, able to live in freshwater, brackish, and even saltwater conditions. Adding a small amount of aquarium salt can improve their overall health.

 Health and Common Issues

• Mollies are generally hardy but can be susceptible to diseases like Ich, fin rot, and fungal infections, particularly if water quality deteriorates.
• Regular water changes and good filtration are essential for keeping them healthy.
