Best Food for Giant African Land Snails

Lissachatina fulica, better known as the Giant African Land Snail (G.A.L.S), ranks among the largest snail species globally. When kept in captivity, these snails necessitate meticulous care encompassing a specialized diet and regulated heating. So, what is the best food for Giant African Land Snails?

The best food for Giant African Land Snails includes vegetables, fruits, and grains. Avoid salt, spices, processed sugars, dairy, and acidic foods. Ensuring a supply of calcium is essential for healthy shell growth. Remember, these adaptable creatures can consume almost any organic matter.

Let us look at the best feeding patterns for Giant African Land Snails.

Fascinating Facts About G.A.L.S

Native to the tropical climates of East Africa, specifically Tanzania and Kenya, the Giant African Land Snail (G.A.L.S) is now found across many parts of the globe. The methods it uses to endure in colder sub-tropical climates are intriguing; the snail can hibernate extensively (aestivation) when temperatures drop too low. The G.A.L.S. is a terrestrial species that breathes through a lung.

Its subspecies may vary in color and size but are generally quite large. As herbivorous species, these snails consume only plant-based materials, feeding on any part of a plant – seeds, leaves, bark, and even the stem during food shortages.

The G.A.L.S. is known for its extensive environmental impact, feeding on almost 500 species of plants. These snails can wreak substantial environmental havoc due to their considerable size, voracious appetite, and rapid reproduction rate.

Furthermore, G.A.L.S. is a known host for the African rat lungworm, which can cause meningitis in humans. Consequently, some states have restricted the movement and sale of this snail species. Nonetheless, they remain widely available in pet stores.

The Natural Diet of Giant African Land Snails

Despite its reputation as a predominantly herbivorous creature, the Giant African Land Snail (G.A.L.S) is more accurately described as a voracious generalist species, willing to consume almost any organic matter it encounters.

This flexibility extends to detritus and even animal protein, as observed in terrarium environments. In their natural habitat, G.A.L.S thrives on a diverse diet that includes: 

  • Vegetables
  • Plants and flowers
  • Fresh leaves and fruits
  • Nuts
  • Dying plants
  • Decaying leaves
  • Bark
  • Seeds
  • Grains
  • Mushrooms
  • Smaller snails
  • Insects 

In terrariums, while the snail adapts to consume whatever food is available, it’s important to note that not all foods are equally beneficial for them. Given their natural inclination towards a herbivorous diet, certain foods are more suitable than others.

To provide optimal care for this snail species, understanding its dietary needs is key. This will enable you to curate a diet that effectively meets its nutritional requirements.

Nutritional Needs of Giant African Land Snails

Like other snails, a G.A.L.S requires a balanced diet to fulfill its nutritional needs. These essential nutrients include: 

  • Energy
  • Protein
  • Vitamins
  • High levels of calcium to support shell growth

It’s crucial to ensure that your Giant African Land Snail’s diet encompasses all these vital components.

As mentioned, G.A.L.S requires significant calcium to facilitate healthy shell growth. Since 98% of a snail’s shell comprises calcium, it is essential to incorporate ample calcium sources in their diet.

Some beneficial calcium sources for your snails include: 

  • Ground coral
  • Ground egg shells
  • Shells of dead snails
  • Cuttlebone

A calcium deficiency can lead to several issues for snails, including: 

  • Slow growth rate.
  • Poor immune function, resulting in reduced healing and regeneration abilities.
  • Snails gnawing on their own shells.
  • Lower reproduction rates.
  • Cracked or malformed shells.

Foods Harmful to Your G.A.L.S

Here’s a list of foods and substances you should never give to your Giant African Land Snails: 

  • Salt: Salt draws water from the snail’s body, potentially leading to dehydration.
  • Spices: These can cause inflammation and drying out.
  • Flour: It’s difficult for snails to digest.
  • Fried Food: There’s a risk that salt, garlic, spices, or onions may have been used during preparation, which can disrupt digestion. The oils used in frying can also harm snails.
  • Smoked Food: Smoke is harmful to snails, potentially causing allergic reactions.
  • Sugary Processed Foods Like Candy: Starches are hard for snails to digest.
  • Dairy Products: They cause digestive issues.
  • Boiled Eggs: The yolk of a boiled egg doesn’t ferment, complicating digestive processes.
  • All Citruses and Lemonades: These are acidic, and snails cannot tolerate acidity.
  • Potato Plant Stem and Leaves: While the potato tuber is okay, the stem and leaves contain solanine, a highly toxic chemical to snails.

How Much Should G.A.L.S Eat?

These large-sized snails are voracious eaters. It’s recommended to feed them at least once a day.

Typically, a snail will consume food equivalent to about 10% of its weight. However, for optimal growth, a snail should eat until it’s full.

An ideal serving for an adult G.A.L.S would be around 0.2 ounces (6 grams) of food per day, with vegetables constituting the largest portion of the diet. Blanch your vegetables, but avoid frying them. Additionally, grains or nuts should not be boiled or cooked.

Closing Remarks
