However, several factors influence their growth, including tank size, water parameters, food availability, and even genetics. While reaching the one-inch mark is possible, it’s more common for them to average around half an inch to three-quarters of an inch in length in a typical home aquarium environment.

Malaysian Trumpet Snails: Care, Feeding, Size & Lifespan

Malaysian Trumpet Snails are a popular choice for freshwater aquariums due to their hardiness, ease of care, and beneficial role in the tank ecosystem. They are detritivores, meaning they eat decomposing organic matter, which helps to keep the tank clean.


  • Malaysian Trumpet Snails are very adaptable and can thrive in a wide range of water conditions. However, they prefer a neutral pH (between 6.5 and 7.5) and a temperature range of 70-80 degrees Fahrenheit.
  • They are also sensitive to copper, so avoid using medications or treatments containing copper in a tank with Malaysian Trumpet Snails.
  • Malaysian Trumpet Snails are burrowers and need a substrate of sand or gravel to thrive. The substrate should be at least a few inches deep so that the snails can burrow into the substrate comfortably.
  • Malaysian Trumpet Snails are generally peaceful community tank inhabitants and will not bother other tank mates or invertebrates. However, they may be eaten by some larger fish, such as puffers and loaches.


  • Malaysian Trumpet Snails are scavengers and will eat a variety of detritus, including leftover fish food, decaying plant matter, and algae.
  • They can also be supplemented with sinking algae wafers, blanched vegetables, or flakes.
  • It is important to avoid overfeeding the tank, as this can lead to an overpopulation of snails and poor water quality.

Size & Lifespan

  • Malaysian Trumpet Snails can grow to be about 1-2 inches long.
  • They have a relatively long lifespan for freshwater snails, with some individuals living up to 5 years in captivity.

Benefits of Malaysian Trumpet Snails

  • Malaysian Trumpet Snails are beneficial for aquariums in several ways.
  • They help to keep the tank clean by eating detritus.
  • They also aerate the substrate as they burrow, which helps to keep the roots of live plants healthy.
  • In addition, red-rimmed melania can help control detritus-eating worms, such as nematodes, in the aquarium.

Breeding Malaysian Trumpet Snails

  • Malaysian Trumpet Snails are livebearers, meaning they give birth to live young.
  • They can reproduce quickly, so it is important to control their population if you do not want them to take over your tank.
  • One way to control the population is to limit the amount of food available to them. You can also remove some of the snails from the tank regularly.
