Golden Apple Snail - L

Species Profile

• Scientific Name: Pomacea bridgesii
• Common Name: Apple Snail (includes color morphs such as blue, gold, ivory, purple, and jade)
• Adult Size: 4–6 cm (1.5–2.5 inches) in shell diameter
• Life Expectancy: 1 to 3 years in captivity, depending on water quality and diet
• Habitat: Native to South America, primarily the Amazon River basin. Found in slow-moving freshwater habitats like swamps, ponds, and rice paddies.

Tank Requirements

• Minimum Tank Size: 10 gallons for one snail; larger tanks recommended for multiple individuals
• Ideal Temperature: 22–28°C (72–82°F)
• pH Range: 7.0–8.0
• Water Hardness: 6–18 dGH (moderate to hard water needed for proper shell development)
• Temperament: Peaceful, solitary, and non-aggressive. Ideal for community aquariums with similarly peaceful tank mates. They may become inactive or float if stressed or if water conditions are poor.

Diet & Nutrition

• Omnivorous: Yes.

  • Eats algae, biofilm, and detritus
  • Supplement with algae wafers, blanched vegetables (zucchini, spinach, cucumber), and calcium-rich foods (e.g., cuttlebone)
  • May nibble on delicate plants if underfed, but usually plant-safe when well-fed
  • Requires calcium for strong shell growth—supplement if necessary

Appearance

• Shell Color: Varies widely – common morphs include gold, blue, ivory, purple, brown, and even striped patterns
• Body Color: Usually ranges from light to dark grey or black, depending on morph
• Size: Grows to the size of a golf ball when fully mature
• Operculum: Has a hard trapdoor to protect itself when retracted into its shell

Distinctive Features

• Air Breather: Has both gills and a lung; can breathe air and may be seen extending a siphon above the waterline
• Egg Laying: Lays pink to white egg clutches above the waterline; easy to spot and remove if population control is needed
• Non-Pest Species: Unlike Pomacea canaliculata (a banned pest species in some regions), P. bridgesii is considered safe and is commonly kept in aquaria
• Excellent Algae Cleaners: Helps control algae and detritus, but not a substitute for proper tank maintenance
