Water Parameters:

  • Water Temperature: Maintain a stable temperature between 22-28°C (72-82 Degrees Fahrenheit).
  • pH Level: Aim for a slightly alkaline pH between 7.0 and 8.0.
  • Water Hardness: Moderately hard water is ideal, providing a natural source of calcium for shell development. If your water is soft, consider adding calcium supplements or a cuttlebone.

Filtration and Aeration:

  • A reliable filter is essential for maintaining water quality and removing waste. Choose a filter that provides gentle water flow, as strong currents can be challenging for snails.
  • Ensure adequate aeration to maintain oxygen levels and prevent stagnant areas within the tank.


  • Moderate lighting is sufficient for Trumpet Snails and their plant companions. Avoid excessive light that can promote excessive algae growth.


  • While Trumpet Snails are efficient algae eaters, they supplement their diet with sinking algae wafers, blanched vegetables like zucchini or spinach, and calcium-rich foods like cuttlebone.


  • Regular water changes (20-30% weekly) should be performed to maintain water quality and prevent the buildup of waste products.
  • Monitor the snail population and take steps to control breeding if necessary.

By providing a suitable environment and meeting their basic needs, you’ll create a thriving haven for your Malaysian Trumpet Snails, allowing them to contribute their algae-eating and substrate-aerating talents to your aquarium ecosystem.

Malaysian Trumpet Snail Care

Malaysian trumpet snails are part of the Thiaridae family, which also includes the Melania snail. These freshwater snail melanoides tuberculata species, also known as Melanois tuberculata, are native to tropical and subtropical regions.

The Malaysian trumpet snail reproduces very quickly in a suitable environment. They breed in a variety of water conditions and can reach sexual maturity in a short amount of time.

Malaysian trumpet snails are slightly larger than males and are known to be motionless at times. They are commonly used in aquariums to help control algae growth, but they also need to be fed plant fertilizers.

If not controlled, the number of snails in an aquarium can quickly increase, causing potential issues for other tank inhabitants.

These snails also serve as an intermediate host for parasites like Melanois tuberculata, which can be transmitted to other tank residents like bamboo shriParasitesites, such as red-rim Melanias, lay eggs in snail’s operculum and can cause harm once Therefore, It’s important to monitor and control the snail population to prevent any potential outbreaks.

Overall, proper care for Malaysian trumpet snails involves maintaining the aquarium water quality, monitoring their reproduction rate, and ensuring they have the necessary nutrients to thrive in a tank environment.

Malaysian Trumpet Snails and Trematodes: A Complex Relationship

The connection between Malaysian Trumpet Snails and trematodes, a type of parasitic flatworm, often raises concerns among aquarium hobbyists. Understanding this relationship is crucial for maintaining a healthy and balanced aquatic environment.

The Trematode Life Cycle:

  • Trematodes have a complex life cycle that typically involves multiple hosts, including snails. Malaysian Trumpet Snails can act as intermediate hosts for certain trematode species.
  • Larval stages of trematodes infect snails, using them as a host to develop and multiply.
  • The trematodes eventually leave the snail and seek a definitive host, usually a fish or bird, to complete their life cycle.

Potential Risks:

  • While Malaysian Trumpet Snails themselves are not directly harmful to fish or humans, the trematodes they carry can pose a risk to fish populations.
  • If infected snails are present in an aquarium with susceptible fish species, the trematodes can infect the fish, causing health problems or even death.

Minimizing Risks:

  • Quarantine New Snails: Before introducing new Malaysian Trumpet Snails to your main tank, quarantine them in a separate aquarium for several weeks to observe for any signs of parasites or disease.
  • Source from Reputable Suppliers: Purchase snails from reputable sources that are known to maintain healthy and parasite-free stock.
  • Maintain a Healthy Aquarium Environment: A clean and well-maintained aquarium with optimal water conditions helps reduce the risk of parasite outbreaks.
  • Observe Fish for Symptoms: Monitor your fish for any signs of illness, such as lethargy, loss of appetite, or unusual behavior, which could indicate a parasitic infection.

Important Note:

  • It’s important to distinguish between different trematode species. Not all trematodes that infect snails pose a risk to fish. Some species have specific host requirements and may not be able to complete their life cycle in a typical aquarium setting.

By understanding the relationship between Malaysian Trumpet Snails and trematodes and taking appropriate precautions, aquarium hobbyists can minimize the risks associated with these parasites and maintain a healthy environment for both snails and fish.
